```
public abstract class AbstractMappingJacksonResponseBodyAdvice
extends Object
implements ResponseBodyAdvice<Object>
```
A convenient base class for ResponseBodyAdvice implementations that customize the response before JSON serialization with AbstractJackson2HttpMessageConverter's concrete subclasses.

Method Summary

All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`Object`	`beforeBodyWrite(Object body, MethodParameter returnType, MediaType contentType, Class<? extends HttpMessageConverter<?>> converterType, ServerHttpRequest request, ServerHttpResponse response)`	Invoked after an `HttpMessageConverter` is selected and just before its write method is invoked.
`protected abstract void`	`beforeBodyWriteInternal(MappingJacksonValue bodyContainer, MediaType contentType, MethodParameter returnType, ServerHttpRequest request, ServerHttpResponse response)`	Invoked only if the converter type is `MappingJackson2HttpMessageConverter`.
`protected MappingJacksonValue`	`getOrCreateContainer(Object body)`	Wrap the body in a `MappingJacksonValue` value container (for providing additional serialization instructions) or simply cast it if already wrapped.
`boolean`	`supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType)`	Whether this component supports the given controller method return type and the selected `HttpMessageConverter` type.

public boolean supports(MethodParameter returnType,
                        Class<? extends HttpMessageConverter<?>> converterType)
```
    Description copied from interface: ResponseBodyAdvice
    Whether this component supports the given controller method return type and the selected HttpMessageConverter type.
    Specified by:
    supports in interface ResponseBodyAdvice<Object>
    Parameters:
    returnType - the return type
    converterType - the selected converter type
    Returns:
    true if ResponseBodyAdvice.beforeBodyWrite(T, org.springframework.core.MethodParameter, org.springframework.http.MediaType, java.lang.Class<? extends org.springframework.http.converter.HttpMessageConverter<?>>, org.springframework.http.server.ServerHttpRequest, org.springframework.http.server.ServerHttpResponse) should be invoked; false otherwise
  - beforeBodyWrite

                                    ServerHttpResponse response)
```
    Description copied from interface: ResponseBodyAdvice
    Invoked after an HttpMessageConverter is selected and just before its write method is invoked.
    Specified by:
    beforeBodyWrite in interface ResponseBodyAdvice<Object>
    Parameters:
    body - the body to be written
    returnType - the return type of the controller method
    contentType - the content type selected through content negotiation
    converterType - the converter type selected to write to the response
    request - the current request
    response - the current response
    Returns:
    the body that was passed in or a modified (possibly new) instance
  - getOrCreateContainer
```
protected MappingJacksonValue getOrCreateContainer(Object body)
```
    Wrap the body in a MappingJacksonValue value container (for providing additional serialization instructions) or simply cast it if already wrapped.
  - beforeBodyWriteInternal
```
protected abstract void beforeBodyWriteInternal(MappingJacksonValue bodyContainer,
                                                MediaType contentType,
                                                MethodParameter returnType,
                                                ServerHttpRequest request,
