类 JsonViewRequestBodyAdvice

java.lang.Object

cn.taketoday.web.handler.method.JsonViewRequestBodyAdvice

所有已实现的接口:

RequestBodyAdvice

public class JsonViewRequestBodyAdvice
extends Object
implements RequestBodyAdvice

A RequestBodyAdvice implementation that adds support for Jackson's @JsonView annotation declared on 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.
