Class ResponseEntityReturnValueHandler

java.lang.Object

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

All Implemented Interfaces:

org.springframework.web.method.support.HandlerMethodReturnValueHandler

public class ResponseEntityReturnValueHandler
extends Object
implements org.springframework.web.method.support.HandlerMethodReturnValueHandler

Handler for return values of type ResponseEntity that delegates to one of the following:

• HttpEntityMethodProcessor for responses with a concrete body value
• ResponseBodyEmitterReturnValueHandler for responses with a body that is a ResponseBodyEmitter or an async/reactive type.

Use of this wrapper allows for late check in handleReturnValue(Object, MethodParameter, ModelAndViewContainer, NativeWebRequest) of the type of the actual body value in case the method signature does not provide enough information to decide via supportsReturnType(MethodParameter).

Since:

6.2.9
