Annotation Type ClientExceptionMapper

@Retention(RUNTIME)
@Target(METHOD)
public @interface ClientExceptionMapper

Used to easily define an exception mapper for the specific REST Client on which it's used. This method is called when the HTTP response from the invoked service has a status code of 400 or higher. The annotation MUST be placed on a method of the REST Client interface that meets the following criteria:

• Is a static method
• Returns any subclass of RuntimeException
• Takes a single parameter of type Response

An example method could look like the following:

 
 @ClientExceptionMapper
 static DummyException map(Response response, Method method) {
     if (response.getStatus() == 404) {
         return new DummyException();
     }
     return null;
 }

 
 

If null is returned, Quarkus will continue searching for matching ResponseExceptionMapper.
