Spring有三个方法名称解析器(MethodNameResolver):
(1)ParameterMethodNameResolver (2)InternalPathMethodNameResolver (3)PropertiesMethodNameResolver 关于三个的使用方法,不必多说,网上可以搜到很多,这里只是简单的提下 ParameterMethodNameResolver在给定的路径后会有一个指定调用哪个方法的参数跟随 例如:http://localhost:9999/method/parameterMethodNameResolver?funcflg=getDate getDate就是要调用的方法 InternalPathMethodNameResolver方法名包含在路径中 http://localhost:9999/method/internalPathMethodController/getDate getDate就是要调用的方法 PropertiesMethodNameResolver 调用的方法写在=后面
http://localhost:9999/method/propertiesMethodController/suibian=getDate getDate就是要调用的方法
相关的XML配置: web.xml
