- org.springframework.web.servlet.mvc.method.annotation.RequestBodyAdviceAdapter

All Implemented Interfaces:
RequestBodyAdvice
Direct Known Subclasses:
JsonViewRequestBodyAdvice
```
public abstract class RequestBodyAdviceAdapter
extends Object
implements RequestBodyAdvice
```
A convenient starting point for implementing ResponseBodyAdvice with default method implementations.
Sub-classes are required to implement RequestBodyAdvice.supports(org.springframework.core.MethodParameter, java.lang.reflect.Type, java.lang.Class<? extends org.springframework.http.converter.HttpMessageConverter<?>>) to return true depending on when the advice applies.

  - handleEmptyBody
```
public Object handleEmptyBody(Object body,
                              HttpInputMessage inputMessage,
                              MethodParameter parameter,
                              Type targetType,
                              Class<? extends HttpMessageConverter<?>> converterType)
```
    The default implementation returns the body that was passed in.
    Specified by:
    handleEmptyBody in interface RequestBodyAdvice
    Parameters:
    body - set to null before the first advice is called
    inputMessage - the request
    parameter - the method parameter
    targetType - the target type, not necessarily the same as the method parameter type, e.g. for HttpEntity<String>.
    converterType - the selected converter type
    Returns:
    the value to use or null which may then raise an HttpMessageNotReadableException if the argument is required.
  - beforeBodyRead
```
public HttpInputMessage beforeBodyRead(HttpInputMessage inputMessage,
                                       MethodParameter parameter,
                                       Type targetType,
                                       Class<? extends HttpMessageConverter<?>> converterType)
                                throws IOException
```
    The default implementation returns the InputMessage that was passed in.
    Specified by:
    beforeBodyRead in interface RequestBodyAdvice
    Parameters:
    inputMessage - the request
    parameter - the target method parameter
    targetType - the target type, not necessarily the same as the method parameter type, e.g. for HttpEntity<String>.
    converterType - the converter used to deserialize the body
    Returns:
    the input request or a new instance, never null
    Throws:
    IOException
  - afterBodyRead
```
public Object afterBodyRead(Object body,
                            HttpInputMessage inputMessage,
                            MethodParameter parameter,
                            Type targetType,
                            Class<? extends HttpMessageConverter<?>> converterType)
```
    The default implementation returns the body that was passed in.
    Specified by:
    afterBodyRead in interface RequestBodyAdvice
    Parameters:
    body - set to the converter Object before the 1st advice is called
    inputMessage - the request
    parameter - the target method parameter
    targetType - the target type, not necessarily the same as the method parameter type, e.g. for HttpEntity<String>.
    converterType - the converter used to deserialize the body
    Returns:
    the same body or a new instance
