各种配置

<!-- 禁用DMI -->
<constant name="struts.enable.DynamicMethodInvocation" value="false"></constant>
<package name="global" namespace="/" extends="struts-default">
</servlet>
<servlet-mapping>
<servlet-name>QueryFilter</servlet-name>
<url-pattern>/query</url-pattern>
</servlet-mapping>
3:监听器：
servlet(servlet filter listener)组件 jsp组件
1.过滤器：
<filter>
<filter-name>MyFilter</filter-name> ====>>> 与下面的filter-name一致
<filter-class>com.cstp.filter.MyFilter</filter-class> ===>>>包名加类名
<action name="*" class="com.cstp.struts.action.MyAction"
method="{1}">
<!-- 引用拦截器站 -->
<interceptor-ref name="mystack"></interceptor-ref>
</action>
"/dtds/struts-2.0.dtd">
<struts>
<!-- 配置struts2框架中的常量 。即配置请求后缀名-->
<constant name="struts.action.extension" value="do"></constant>
<result name="success" type="redirectAction">skip(这里不需要加'/')</result>
</action>
</package>
<package name="skip" namespace="/" extends="global">
<description></description>
<display-name>QueryFilter</display-name>
<servlet-name>QueryFilter</servlet-name>
<servlet-class>com.cstp.servlet.QueryFilter</servlet-class>
</action>
</package>
<!--
====>>>从login跳转到action skip url位置不需要加'/'
<package name="user" namespace="/" extends="global">
<action name="login" class="com.cstp.struts.action.LoginAction">
</filter>
<filter-mapping>
<filter-name>MyFilter</filter-name>
<url-pattern>/query</url-pattern>
</filter-mapping>
2.servlet：
<servlet>
<struts>
<!-- 配置全局跳转 设置其abstract熟悉为true，则其它action继承该action就 可以实现跳转 -->
<package name="global" namespace="/" extends="struts-default"
abstract="true">
</package>
</struts>
