public interface ResponseBodyAdvice<T>
```
Allows customizing the response after the execution of an @ResponseBody or a ResponseEntity controller method but before the body is written with an HttpMessageConverter.
Implementations may be registered directly with RequestMappingHandlerAdapter and ExceptionHandlerExceptionResolver or more likely annotated with @ControllerAdvice in which case they will be auto-detected by both.
