Spencer Gibb 727d8be2dc Change from @Autowired to context.getBean.
Solves problems where FeignClientFactoryBean is run before auto-configuration.

fixed gh-441
2015-10-14 11:52:11 -06:00
Dave Syer f98a7d5bc5 Take into account secure port settings when looking for config server
When the config server is located via discovery
(spring.cloud.config.discovery.enabled=true) the discovery process
should attempt to establish whether the config server prefers to
be accessed securely (e.g. it registered with Eureka as
nonSecurePortEnabled=false). This change ensures that this happens.

Fixes gh-450
2015-09-25 13:09:33 +01:00
Dave Syer 5dccd03d73 Fix broken test
This test made wrong assumptions about the content of the child
context when trying to simulate autoconfiguration. It needed
an extra EurekaClientAutoConfiguration.
2015-09-25 13:04:52 +01:00
Dave Syer f904b52a1d Tweak eureka lifecycle so it re-registers after a refresh
This version of Eureka is a bit of a singleton pig, so it's hard
to control the lifecycle, but this seems to work for all the tests
and also the eureka-first and ribbon-eureka samples.

Fixes gh-551 for 1.0.x

# Contributing
Spring Cloud is released under the non-restrictive Apache 2.0 license,
and follows a very standard Github development process, using Github
tracker for issues and merging pull requests into main. If you want
to contribute even something trivial please do not hesitate, but
follow the guidelines below.
## Sign the Contributor License Agreement
Before we accept a non-trivial patch or pull request we will need you to sign the
[Contributor License Agreement](https://cla.pivotal.io/sign/spring).
Signing the contributor's agreement does not grant anyone commit rights to the main
repository, but it does mean that we can accept your contributions, and you will get an
author credit if we do. Active contributors might be asked to join the core team, and
given the ability to merge pull requests.
## Code of Conduct
This project adheres to the Contributor Covenant [code of
conduct](https://github.com/spring-cloud/spring-cloud-build/blob/main/docs/src/main/asciidoc/code-of-conduct.adoc). By participating, you are expected to uphold this code. Please report
unacceptable behavior to spring-code-of-conduct@pivotal.io.
## Code Conventions and Housekeeping
None of these is essential for a pull request, but they will all help. They can also be
added after the original pull request but before a merge.
* Use the Spring Framework code format conventions. If you use Eclipse
you can import formatter settings using the
`eclipse-code-formatter.xml` file from the
[Spring Cloud Build](https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/main/spring-cloud-dependencies-parent/eclipse-code-formatter.xml) project. If using IntelliJ, you can use the
[Eclipse Code Formatter Plugin](https://plugins.jetbrains.com/plugin/6546) to import the same file.
* Make sure all new `.java` files to have a simple Javadoc class comment with at least an
`@author` tag identifying you, and preferably at least a paragraph on what the class is
for.
* Add the ASF license header comment to all new `.java` files (copy from existing files
in the project)
* Add yourself as an `@author` to the .java files that you modify substantially (more
than cosmetic changes).
* Add some Javadocs and, if you change the namespace, some XSD doc elements.
* A few unit tests would help a lot as well -- someone has to do it.
* If no-one else is using your branch, please rebase it against the current main (or
other target branch in the main project).
* When writing a commit message please follow [these conventions](https://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html),
if you are fixing an existing issue please add `Fixes gh-XXXX` at the end of the commit
message (where XXXX is the issue number).

"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works

attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must

pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

image::https://travis-ci.org/spring-cloud/spring-cloud-netflix.svg?branch=master[Build Status, link=https://travis-ci.org/spring-cloud/spring-cloud-netflix]
This project provides Netflix OSS integrations for Spring Boot apps through autoconfiguration
and binding to the Spring Environment and other Spring programming model idioms. With a few
simple annotations you can quickly enable and configure the common patterns inside your
application and build large distributed systems with battle-tested Netflix components. The
patterns provided include Service Discovery (Eureka).
patterns provided include Service Discovery (Eureka), Circuit Breaker (Hystrix),
Intelligent Routing (Zuul) and Client Side Load Balancing (Ribbon).
== Features
* Service Discovery: Eureka instances can be registered and clients can discover the instances using Spring-managed beans
* Service Discovery: an embedded Eureka server can be created with declarative Java configuration
* Circuit Breaker: Hystrix clients can be built with a simple annotation-driven method decorator
* Circuit Breaker: embedded Hystrix dashboard with declarative Java configuration
* Declarative REST Client: Feign creates a dynamic implementation of an interface decorated with JAX-RS or Spring MVC annotations
* Client Side Load Balancer: Ribbon
* External Configuration: a bridge from the Spring Environment to Archaius (enables native configuration of Netflix components using Spring Boot conventions)
* Router and Filter: automatic regsitration of Zuul filters, and a simple convention over configuration approach to reverse proxy creation
== Building
:jdkversion: 17
:jdkversion: 1.8
=== Basic Compile and Test
To build the source you will need to install JDK {jdkversion}.
To build the source you will need to install
http://maven.apache.org/run-maven/index.html[Apache Maven] v3.0.6 or above and JDK {jdkversion}.
Spring Cloud uses Maven for most build-related activities, and you
should be able to get off the ground quite quickly by cloning the
project you are interested in and typing
----
$ ./mvnw install
$ mvn install -s .settings.xml
----
NOTE: You can also install Maven (>=3.3.3) yourself and run the `mvn` command
in place of `./mvnw` in the examples below. If you do that you also
might need to add `-P spring` if your local Maven settings do not
contain repository declarations for spring pre-release artifacts.
NOTE: You may need to increase the amount of memory available to Maven by setting
a `MAVEN_OPTS` environment variable with the value `-Xmx512m -XX:MaxPermSize=128m`
NOTE: Be aware that you might need to increase the amount of memory
available to Maven by setting a `MAVEN_OPTS` environment variable with
a value like `-Xmx512m -XX:MaxPermSize=128m`. We try to cover this in
the `.mvn` configuration, so if you find you have to do it to make a
build succeed, please raise a ticket to get the settings added to
source control.
The `.settings.xml` is only required the first time (or after updates
to dependencies). It is there to provide repository declarations so
that those do not need to be hard coded in the project poms.
The projects that require middleware (i.e. Redis) for testing generally
require that a local instance of [Docker](https://www.docker.com/get-started) is installed and running.
For hints on how to build the project look in `.travis.yml` if there
is one. There should be a "script" and maybe "install" command. Also
look at the "services" section to see if any services need to be
running locally (e.g. mongo or rabbit). Ignore the git-related bits
that you might find in "before_install" since they will be able git
credentials and you already have those.
If you need mongo, rabbit or redis, see the README in the https://github.com/spring-cloud-samples/scripts[scripts
demo repository] for
instructions. For example consider using the "fig.yml" with
http://www.fig.sh/[Fig] to run them in Docker containers.

any changes in the README it will then show up after a Maven build as
a modified file in the correct place. Just commit it and push the change.
=== Working with the code
If you don't have an IDE preference we would recommend that you use
https://www.springsource.com/developer/sts[Spring Tools Suite] or
https://eclipse.org[Eclipse] when working with the code. We use the
https://eclipse.org/m2e/[m2eclipse] eclipse plugin for maven support. Other IDEs and tools
should also work without issue as long as they use Maven 3.3.3 or better.
==== Activate the Spring Maven profile
Spring Cloud projects require the 'spring' Maven profile to be activated to resolve
the spring milestone and snapshot repositories. Use your preferred IDE to set this
profile to be active, or you may experience build errors.
==== Importing into eclipse with m2eclipse
We recommend the https://eclipse.org/m2e/[m2eclipse] eclipse plugin when working with
eclipse. If you don't already have m2eclipse installed it is available from the "eclipse
marketplace".
NOTE: Older versions of m2e do not support Maven 3.3, so once the
projects are imported into Eclipse you will also need to tell
m2eclipse to use the right profile for the projects. If you
see many different errors related to the POMs in the projects, check
that you have an up to date installation. If you can't upgrade m2e,
add the "spring" profile to your `settings.xml`. Alternatively you can
copy the repository settings from the "spring" profile of the parent
pom into your `settings.xml`.
==== Importing into eclipse without m2eclipse
If you prefer not to use m2eclipse you can generate eclipse project metadata using the
following command:
[indent=0]
----
$ ./mvnw eclipse:eclipse
----
The generated eclipse projects can be imported by selecting `import existing projects`
from the `file` menu.
NOTE: To build the module `spring-cloud-netflix-hystrix-contract` along with the entire Netflix project run the
`build.sh` script in the `scripts` directory.

==== Sign the Contributor License Agreement
Before we accept a non-trivial patch or pull request we will need you
to sign the
https://support.springsource.com/spring_committer_signup[contributor's
agreement]. Signing the contributor's agreement does not grant anyone
commit rights to the main repository, but it does mean that we can
accept your contributions, and you will get an author credit if we do.
Active contributors might be asked to join the core team, and given
the ability to merge pull requests.
==== Code Conventions and Housekeeping
None of these is essential for a pull request, but they will all help. They can also be
added after the original pull request but before a merge.
* Use the Spring Framework code format conventions. If you use Eclipse and you follow
the ``Importing into eclipse'' instructions below you should get project specific
formatting automatically. You can also import formatter settings using the
`eclipse-code-formatter.xml` file from the `eclipse` folder. If using IntelliJ, you can
use the http://plugins.jetbrains.com/plugin/6546[Eclipse Code Formatter Plugin]
to import the same file.
* Make sure all new `.java` files to have a simple Javadoc class comment with at least an
`@author` tag identifying you, and preferably at least a paragraph on what the class is
for.
* Add the ASF license header comment to all new `.java` files (copy from existing files
in the project)
* Add yourself as an `@author` to the .java files that you modify substantially (more
than cosmetic changes).
* Add some Javadocs and, if you change the namespace, some XSD doc elements.
* A few unit tests would help a lot as well -- someone has to do it.

shouldn't cause any problems, but in an IDE you need to add an agent
to the JVM. Full instructions can be found in the Lombok website. The

=== Checkstyle
Spring Cloud Build comes with a set of checkstyle rules. You can find them in the `spring-cloud-build-tools` module. The most notable files under the module are:
.spring-cloud-build-tools/
----
└── src
   ├── checkstyle
   │   └── checkstyle-suppressions.xml <3>
   └── main
   └── resources
   ├── checkstyle-header.txt <2>
   └── checkstyle.xml <1>
----
<1> Default Checkstyle rules
<2> File header setup
<3> Default suppression rules
==== Checkstyle configuration
Checkstyle rules are *disabled by default*. To add checkstyle to your project just define the following properties and plugins.
.pom.xml
----
<properties>
<maven-checkstyle-plugin.failsOnError>true</maven-checkstyle-plugin.failsOnError> <1>
<maven-checkstyle-plugin.failsOnViolation>true
</maven-checkstyle-plugin.failsOnViolation> <2>
<maven-checkstyle-plugin.includeTestSourceDirectory>true
</maven-checkstyle-plugin.includeTestSourceDirectory> <3>
</properties>

<artifactId>spring-javaformat-maven-plugin</artifactId>
</plugin>
<plugin> <5>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-checkstyle-plugin</artifactId>
</plugin>

<plugins>
<plugin> <5>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-checkstyle-plugin</artifactId>
</plugin>
</plugins>
</reporting>
</build>
----
<1> Fails the build upon Checkstyle errors
<2> Fails the build upon Checkstyle violations
<3> Checkstyle analyzes also the test sources
<4> Add the Spring Java Format plugin that will reformat your code to pass most of the Checkstyle formatting rules
<5> Add checkstyle plugin to your build and reporting phases
If you need to suppress some rules (e.g. line length needs to be longer), then it's enough for you to define a file under `${project.root}/src/checkstyle/checkstyle-suppressions.xml` with your suppressions. Example:
.projectRoot/src/checkstyle/checkstyle-suppresions.xml
----
<?xml version="1.0"?>
<!DOCTYPE suppressions PUBLIC
"-//Puppy Crawl//DTD Suppressions 1.1//EN"
"https://www.puppycrawl.com/dtds/suppressions_1_1.dtd">
<suppressions>
<suppress files=".*ConfigServerApplication\.java" checks="HideUtilityClassConstructor"/>
<suppress files=".*ConfigClientWatch\.java" checks="LineLengthCheck"/>
</suppressions>
----
It's advisable to copy the `${spring-cloud-build.rootFolder}/.editorconfig` and `${spring-cloud-build.rootFolder}/.springformat` to your project. That way, some default formatting rules will be applied. You can do so by running this script:
```bash
$ curl https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/.editorconfig -o .editorconfig
$ touch .springformat
```
=== IDE setup
==== Intellij IDEA
In order to setup Intellij you should import our coding conventions, inspection profiles and set up the checkstyle plugin.
The following files can be found in the https://github.com/spring-cloud/spring-cloud-build/tree/master/spring-cloud-build-tools[Spring Cloud Build] project.
.spring-cloud-build-tools/

.Code style
image::https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/{spring-cloud-build-branch}/docs/src/main/asciidoc/images/intellij-code-style.png[Code style]
Go to `File` -> `Settings` -> `Editor` -> `Code style`. There click on the icon next to the `Scheme` section. There, click on the `Import Scheme` value and pick the `Intellij IDEA code style XML` option. Import the `spring-cloud-build-tools/src/main/resources/intellij/Intellij_Spring_Boot_Java_Conventions.xml` file.
.Inspection profiles
image::https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/{spring-cloud-build-branch}/docs/src/main/asciidoc/images/intellij-inspections.png[Code style]
Go to `File` -> `Settings` -> `Editor` -> `Inspections`. There click on the icon next to the `Profile` section. There, click on the `Import Profile` and import the `spring-cloud-build-tools/src/main/resources/intellij/Intellij_Project_Defaults.xml` file.
.Checkstyle
To have Intellij work with Checkstyle, you have to install the `Checkstyle` plugin. It's advisable to also install the `Assertions2Assertj` to automatically convert the JUnit assertions
image::https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/{spring-cloud-build-branch}/docs/src/main/asciidoc/images/intellij-checkstyle.png[Checkstyle]
Go to `File` -> `Settings` -> `Other settings` -> `Checkstyle`. There click on the `+` icon in the `Configuration file` section. There, you'll have to define where the checkstyle rules should be picked from. In the image above, we've picked the rules from the cloned Spring Cloud Build repository. However, you can point to the Spring Cloud Build's GitHub repository (e.g. for the `checkstyle.xml` : `https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/main/resources/checkstyle.xml`). We need to provide the following variables:
- `checkstyle.header.file` - please point it to the Spring Cloud Build's, `spring-cloud-build-tools/src/main/resources/checkstyle-header.txt` file either in your cloned repo or via the `https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/main/resources/checkstyle-header.txt` URL.
- `checkstyle.suppressions.file` - default suppressions. Please point it to the Spring Cloud Build's, `spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml` file either in your cloned repo or via the `https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml` URL.
- `checkstyle.additional.suppressions.file` - this variable corresponds to suppressions in your local project. E.g. you're working on `spring-cloud-contract`. Then point to the `project-root/src/checkstyle/checkstyle-suppressions.xml` folder. Example for `spring-cloud-contract` would be: `/home/username/spring-cloud-contract/src/checkstyle/checkstyle-suppressions.xml`.
IMPORTANT: Remember to set the `Scan Scope` to `All sources` since we apply checkstyle rules for production and test sources.
=== Duplicate Finder
Spring Cloud Build brings along the `basepom:duplicate-finder-maven-plugin`, that enables flagging duplicate and conflicting classes and resources on the java classpath.
==== Duplicate Finder configuration
Duplicate finder is *enabled by default* and will run in the `verify` phase of your Maven build, but it will only take effect in your project if you add the `duplicate-finder-maven-plugin` to the `build` section of the projecst's `pom.xml`.
.pom.xml
[source,xml]
----
<build>
<plugins>
<plugin>
<groupId>org.basepom.maven</groupId>
<artifactId>duplicate-finder-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
----
For other properties, we have set defaults as listed in the https://github.com/basepom/duplicate-finder-maven-plugin/wiki[plugin documentation].
You can easily override them but setting the value of the selected property prefixed with `duplicate-finder-maven-plugin`. For example, set `duplicate-finder-maven-plugin.skip` to `true` in order to skip duplicates check in your build.
If you need to add `ignoredClassPatterns` or `ignoredResourcePatterns` to your setup, make sure to add them in the plugin configuration section of your project:
[source,xml]
----
<build>
<plugins>
<plugin>
<groupId>org.basepom.maven</groupId>
<artifactId>duplicate-finder-maven-plugin</artifactId>

This project provides Netflix OSS integrations for Spring Boot apps through autoconfiguration
and binding to the Spring Environment and other Spring programming model idioms. With a few
simple annotations you can quickly enable and configure the common patterns inside your
application and build large distributed systems with battle-tested Netflix components. The
patterns provided include Service Discovery (Eureka), Circuit Breaker (Hystrix),
Intelligent Routing (Zuul) and Client Side Load Balancing (Ribbon).
== Features
* Service Discovery: Eureka instances can be registered and clients can discover the instances using Spring-managed beans
* Service Discovery: an embedded Eureka server can be created with declarative Java configuration
* Circuit Breaker: Hystrix clients can be built with a simple annotation-driven method decorator
* Circuit Breaker: embedded Hystrix dashboard with declarative Java configuration
* Declarative REST Client: Feign creates a dynamic implementation of an interface decorated with JAX-RS or Spring MVC annotations
* Client Side Load Balancer: Ribbon
* External Configuration: a bridge from the Spring Environment to Archaius (enables native configuration of Netflix components using Spring Boot conventions )
* Router and Filter: automatic registration of Zuul filters, and a simple convention over configuration approach to reverse proxy creation

|Name | Default | Description
|eureka.client.eureka-connection-idle-timeout-seconds | `30` | Indicates how much time (in seconds) that the HTTP connections to eureka server can stay idle before it can be closed. In the AWS environment, it is recommended that the values is 30 seconds or less, since the firewall cleans up the connection information after a few mins leaving the connection hanging in limbo.
|eureka.client.eureka-server-connect-timeout-seconds | `5` | Indicates how long to wait (in seconds) before a connection to eureka server needs to timeout. Note that the connections in the client are pooled by org.apache.http.client.HttpClient and this setting affects the actual connection creation and also the wait time to get the connection from the pool.
|eureka.client.eureka-server-d-n-s-name | | Gets the DNS name to be queried to get the list of eureka servers.This information is not required if the contract returns the service urls by implementing serviceUrls. The DNS mechanism is used when useDnsForFetchingServiceUrls is set to true and the eureka client expects the DNS to configured a certain way so that it can fetch changing eureka servers dynamically. The changes are effective at runtime.
|eureka.client.eureka-server-port | | Gets the port to be used to construct the service url to contact eureka server when the list of eureka servers come from the DNS.This information is not required if the contract returns the service urls eurekaServerServiceUrls(String). The DNS mechanism is used when useDnsForFetchingServiceUrls is set to true and the eureka client expects the DNS to configured a certain way so that it can fetch changing eureka servers dynamically. The changes are effective at runtime.
|eureka.client.eureka-server-read-timeout-seconds | `8` | Indicates how long to wait (in seconds) before a read from eureka server needs to timeout.
|eureka.client.eureka-server-total-connections | `200` | Gets the total number of connections that is allowed from eureka client to all eureka servers.
|eureka.client.eureka-server-total-connections-per-host | `50` | Gets the total number of connections that is allowed from eureka client to a eureka server host.
|eureka.client.eureka-server-u-r-l-context | | Gets the URL context to be used to construct the service url to contact eureka server when the list of eureka servers come from the DNS. This information is not required if the contract returns the service urls from eurekaServerServiceUrls. The DNS mechanism is used when useDnsForFetchingServiceUrls is set to true and the eureka client expects the DNS to configured a certain way so that it can fetch changing eureka servers dynamically. The changes are effective at runtime.
|eureka.client.eureka-service-url-poll-interval-seconds | `0` | Indicates how often(in seconds) to poll for changes to eureka server information. Eureka servers could be added or removed and this setting controls how soon the eureka clients should know about it.
|eureka.client.prefer-same-zone-eureka | `true` | Indicates whether or not this instance should try to use the eureka server in the same zone for latency and/or other reason. Ideally eureka clients are configured to talk to servers in the same zone The changes are effective at runtime at the next registry fetch cycle as specified by registryFetchIntervalSeconds
|eureka.client.register-with-eureka | `true` | Indicates whether or not this instance should register its information with eureka server for discovery by others. In some cases, you do not want your instances to be discovered whereas you just want do discover other instances.
|eureka.server.peer-eureka-nodes-update-interval-ms | `0` |
|eureka.server.peer-eureka-status-refresh-time-interval-ms | `0` |
|ribbon.eureka.enabled | `true` | Enables the use of Eureka with Ribbon.
|spring.cloud.loadbalancer.eureka.approximate-zone-from-hostname | `false` | Used to determine whether we should try to get the `zone` value from host name.

The idea of this script is to update gh-pages branch with the generated docs. Without any options
the script will work in the following manner:
- if there's no gh-pages / target for docs module then the script ends
- for main branch the generated docs are copied to the root of gh-pages branch
- for any other branch (if that branch is allowed) a subfolder with branch name is created
and docs are copied there
- if the version switch is passed (-v) then a tag with (v) prefix will be retrieved and a folder
with that version number will be created in the gh-pages branch. WARNING! No allow verification will take place
- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
switch to gh-pages of that repo and copy the generated docs to `docs/<project-name>/<version>`
- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
switch to gh-pages of that repo and copy the generated docs to `docs/<project-name>/<version>`
USAGE:
You can use the following options:
-v|--version - the script will apply the whole procedure for a particular library version
-d|--destination - the root of destination folder where the docs should be copied. You have to use the full path.
E.g. point to spring-cloud-static folder. Can't be used with (-c)
-b|--build - will run the standard build process after checking out the branch
-c|--clone - will automatically clone the spring-cloud-static repo instead of providing the destination.
Obviously can't be used with (-d)

Spring Cloud Netflix provides Netflix OSS integrations for Spring Boot apps through autoconfiguration and binding to the Spring Environment and other Spring programming model idioms. With a few simple annotations you can quickly enable and configure the common patterns inside your application and build large distributed systems with battle-tested Netflix components. The patterns provided include Service Discovery (Eureka).
## Features
Spring Cloud Netflix features:
* Service Discovery: Eureka instances can be registered and clients can discover the instances using Spring-managed beans
* Service Discovery: an embedded Eureka server can be created with declarative Java configuration
## Getting Started
As long as Spring Cloud Netflix and Eureka Core are on the
classpath any Spring Boot application with `spring-cloud-starter-netflix-eureka-client` in dependencies will try to contact a Eureka
server on `http://localhost:8761` (the default value of
`eureka.client.serviceUrl.defaultZone`):
```java
@SpringBootApplication
@RestController
public class Application {
@RequestMapping("/")
public String home() {
return "Hello World";
}
public static void main(String[] args) {
