类 ModelMethodProcessor

java.lang.Object

cn.taketoday.web.bind.resolver.ModelMethodProcessor

所有已实现的接口:

ParameterResolvingStrategy, ReturnValueHandler

public class ModelMethodProcessor
extends Object
implements ReturnValueHandler, ParameterResolvingStrategy

Resolves Model arguments and handles Model return values.

A Model 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.
