Spring三大URL路径解析器（附工程源代码）

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

最后工程的访问路径为

ParameterMethodNameResolver  http://localhost:9999/method/parameterMethodNameResolver?funcflg=getDate

InternalPathMethodNameResolver  http://localhost:9999/method/internalPathMethodController/getDate

PropertiesMethodNameResolver  http://localhost:9999/method/propertiesMethodController/suibian=getDate
