Annotation Type ServerResponseFilter

@Retention(value=RUNTIME)
 @Target(value=METHOD)
public @interface ServerResponseFilter

When used on a method, then an implementation of ContainerResponseContext is generated that calls the annotated method with the proper arguments The idea behind using this is to make it much to write a ServerResponseFilter as all the necessary information is passed as arguments to the method instead of forcing the author to use a mix of @Context and programmatic CDI look-ups.

An example filter could look like this:

 public class CustomContainerResponseFilter {

     private final SomeBean someBean;

     // SomeBean will be automatically injected by CDI as long as SomeBean is a bean itself
     public CustomContainerResponseFilter(SomeBean someBean) {
         this.someBean = someBean;
     }

     @ServerResponseFilter
     public void whatever(SimplifiedResourceInfo resourceInfo) {
         // do something
     }
 }
 

Methods annotated with ServerRequestFilter can declare any of the following parameters (in any order)

• ContainerRequestContext
• ContainerResponseContext
• ResourceInfo
• SimpleResourceInfo
• Throwable - The thrown exception - or null if no exception was thrown

The return type of the method must be either be of type void or Uni<Void>.

• void should be used when filtering does not need to perform any blocking operations.
• Uni<Void> should be used when filtering needs to perform a blocking operations.

Another important thing to note is that if ContainerRequestContext is used as a request parameter, calling abortWith is prohibited by the JAX-RS specification.
