Class ViewNameMethodReturnValueHandler
java.lang.Object
org.springframework.web.servlet.mvc.method.annotation.ViewNameMethodReturnValueHandler
- All Implemented Interfaces:
- org.springframework.web.method.support.HandlerMethodReturnValueHandler
public class ViewNameMethodReturnValueHandler
- extends java.lang.Object
- implements org.springframework.web.method.support.HandlerMethodReturnValueHandler
Handles return values of types void
and String
interpreting
them as view name reference.
A null
return value, either due to a void
return type or
as the actual return value is left as-is allowing the configured
RequestToViewNameTranslator
to select a view name by convention.
A String return value can be interpreted in more than one ways depending
on the presence of annotations like @ModelAttribute
or
@ResponseBody
. Therefore this handler should be configured after
the handlers that support these annotations.
