[[rest-http-interface-adapter-decorator]]
=== Decorating the Adapter
`HttpExchangeAdapter` and `ReactorHttpExchangeAdapter` are contracts that decouple HTTP
Interface client infrastructure from the details of invoking the underlying
client. There are adapter implementations for `RestClient`, `WebClient`, and
`RestTemplate`.
Occasionally, it may be useful to intercept client invocations through a decorator
configurable in the `HttpServiceProxyFactory.Builder`. For example, you can apply
built-in decorators to suppress 404 exceptions and return a `ResponseEntity` with
`NOT_FOUND` and a `null` body:

----
// For RestClient
HttpServiceProxyFactory factory = HttpServiceProxyFactory.builderFor(restCqlientAdapter)
.exchangeAdapterDecorator(NotFoundRestClientAdapterDecorator::new)
.build();
// or for WebClient...
HttpServiceProxyFactory proxyFactory = HttpServiceProxyFactory.builderFor(webClientAdapter)
.exchangeAdapterDecorator(NotFoundWebClientAdapterDecorator::new)
.build();
