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

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(java.lang.Object, org.springframework.core.MethodParameter, org.springframework.web.method.support.ModelAndViewContainer, org.springframework.web.context.request.NativeWebRequest) of the type of the actual body value in case the method signature does not provide enough information to decide via supportsReturnType(org.springframework.core.MethodParameter).
