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

Class ViewMethodReturnValueHandler

java.lang.Object

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

All Implemented Interfaces:

org.springframework.web.method.support.HandlerMethodReturnValueHandler

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

Handles return values that are of type View.

A null return value is left as-is leaving it to the configured RequestToViewNameTranslator to select a view name by convention.

A View return type has a set purpose. Therefore this handler should be configured ahead of handlers that support any return value type annotated with @ModelAttribute or @ResponseBody to ensure they don't take over.

3.1
