SpringMVC MultiActionController 默认方法名解析器

MultiActionController默认方法名解析器
是指在请求的地址中加入指定方法名称

MultiActionController类具有一个属性methodNameResolver,方法名解析器：其具有默认值InternalPathMethodNameResolver,该解析器将方法名作为资源名称进行解析，那就意味着，我们提交请求时，要将方法名作为资源名称出现。

方法名解析器： PropertiesMethodNameResolver  是 <bean id="myMultiController" class="cn.kitty.controller.MyMultiController">的属性。

默认方法名：MultiActionController
