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

所有已实现的接口:
RequestBodyAdvice
```
public class JsonViewRequestBodyAdvice
extends RequestBodyAdviceAdapter
```
A RequestBodyAdvice implementation that adds support for Jackson's @JsonView annotation declared on a Spring MVC @HttpEntity or @RequestBody method parameter.
The deserialization view specified in the annotation will be passed in to the MappingJackson2HttpMessageConverter which will then use it to deserialize the request body with.
Note that despite @JsonView allowing for more than one class to be specified, the use for a request body advice is only supported with exactly one class argument. Consider the use of a composite interface.
Jackson 2.5 or later is required for parameter-level use of @JsonView.
从以下版本开始:
4.2

    Invoked first to determine if this interceptor applies.
    参数:
    methodParameter - 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
    返回:
    whether this interceptor should be invoked or not

```
public HttpInputMessage beforeBodyRead(HttpInputMessage inputMessage,

    从类复制的说明: RequestBodyAdviceAdapter
    The default implementation returns the InputMessage that was passed in.
    指定者:
    beforeBodyRead 在接口中 RequestBodyAdvice
    覆盖:
    beforeBodyRead 在类中 RequestBodyAdviceAdapter

    selectedConverterType - the converter used to deserialize the body
    返回:
    the input request or a new instance, never null
    抛出:
    IOException
