When a request fails, you may want to have the request be retried automatically.
To do so when using Sping Cloud Netflix, you need to include <a class="link" href="https://github.com/spring-projects/spring-retry" target="_top">Spring Retry</a> on your application&#8217;s classpath.
When Spring Retry is present, load-balanced <code class="literal">RestTemplates</code>, Feign, and Zuul automatically retry any failed requests (assuming your configuration allows doing so).</p><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="_backoff_policies" href="#_backoff_policies"></a>10.1&nbsp;BackOff Policies</h2></div></div></div><p>By default, no backoff policy is used when retrying requests.
If you would like to configure a backoff policy, you need to create a bean of type <code class="literal">LoadBalancedBackOffPolicyFactory</code>, which is used to create a <code class="literal">BackOffPolicy</code> for a given service, as shown in the following example:</p><pre class="programlisting"><em><span class="hl-annotation" style="color: gray">@Configuration</span></em>
If you would like to configure a backoff policy, you need to create a bean of type <code class="literal">LoadBalancedRetryFactory</code> and override the <code class="literal">createBackOffPolicy</code> method for a given service, as shown in the following example:</p><pre class="programlisting"><em><span class="hl-annotation" style="color: gray">@Configuration</span></em>
