struts.xml
<struts>
<!-- 常量配置 -->
<constant name="struts.i18n.encoding" value="utf-8"></constant>
<constant name="struts.action.extension" value="action,do,"></constant>
<!-- 当前框架处于开发状态，易于调试。上线时改为false -->
<constant name="struts.devMode" value="true"></constant>
<include file="struts-*.xml"></include>
<!-- 项目基础包 -->
<package name="base" extends="struts-default" >
<interceptors>
<!-- 定义拦截器 -->
<interceptor name="mylg" class="com.it.intercp.MyLogger"></interceptor>
<!-- 定义拦截器栈-->
<interceptor-stack name="tk">
<interceptor-ref name="defaultStack"></interceptor-ref>
<interceptor-ref name="mylg"></interceptor-ref>
</interceptor-stack>
</interceptors>
</package>
</struts>
syruts-user.xml
<!-- 建立用户业务逻辑包 -->
<package name="userLogic" namespace="/users" extends="base">
<!-- 定义一拦截器 -->
<default-interceptor-ref name="tk"></default-interceptor-ref>
<!-- 添加Action -->
<action name="add" class="com.it.action.UserOptAction" method="addUser">
<result name="ok" type="chain">show</result>
<!-- 令牌拦截器，防止重复提交 -->
<result name="invalid.token" type="redirect">/users/x.html</result>
</action>
<!-- 删除Action -->
<action name="del" class="com.it.action.UserOptAction" method="delUser">

</action>
<!-- 修改Action -->
<action name="upd" class="com.it.action.UserOptAction" method="updUser">

</action>
<!-- 查询一个User,Action -->
<action name="findOne" class="com.it.action.UserFindAction" method="findOne" >
