Class JsonViewResponseBodyAdvice

org.springframework.web.servlet.mvc.method.annotation.AbstractMappingJacksonResponseBodyAdvice

org.springframework.web.servlet.mvc.method.annotation.JsonViewResponseBodyAdvice

All Implemented Interfaces:

ResponseBodyAdvice<Object>

public class JsonViewResponseBodyAdvice
extends AbstractMappingJacksonResponseBodyAdvice

A ResponseBodyAdvice implementation that adds support for Jackson's @JsonView annotation declared on a Spring MVC @RequestMapping or @ExceptionHandler method.

The serialization view specified in the annotation will be passed in to the MappingJackson2HttpMessageConverter which will then use it to serialize the response body.

Note that despite @JsonView allowing for more than one class to be specified, the use for a response body advice is only supported with exactly one class argument. Consider the use of a composite interface.

Since:

4.1
