通过一定的规则讲url上的参数绑定到action。 可以匹配例如：info/{id}/{group}/{userName} ->info1/admin/joe.do，同时讲参数id，group，userName 绑定到action的对应的属性上。

使用：

<package name="base" extends="simplerest-default">

</package>

<package name="base" extends="struts-default">

<interceptors>

class="com.joe.struts2.plugin.simpleresturl.SimpleRestUrlInterceptor"/>

<interceptor-stack name="simpleRestUrlInterceptorStack">

<interceptor-ref name="simpleRestUrlInterceptor" />

<interceptor-ref name="defaultStack" />

</interceptor-stack>

</interceptors>

</package>

-->

<package name="userinfo" namespace="/userinfo" extends="base">

<default-interceptor-ref name="simpleRestUrlInterceptorStack"/>

<action name="info/{id}" class="com.demo.simpleresturl.module.action.UserAction" method="info">

<result >

/WEB-INF/user/user-info.jsp

</result>

</action>

<action name="info/{id}/{group}" class="com.demo.simpleresturl.module.action.UserAction" method="info">

<result >

/WEB-INF/user/user-info.jsp

</result>

</action>

<action name="info/{id}/{group}/{userName}" class="com.demo.simpleresturl.module.action.UserAction" method="info">

<result >

/WEB-INF/user/user-info.jsp

</result>

</action>

<action name="info/1" class="com.demo.simpleresturl.module.action.UserAction" method="info">

<result >

/WEB-INF/user/user-info.jsp

</result>

</action>

</package>
