建立WEB-INF/web.xml

web.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <display-name>ssh</display-name>
    <!-- spring配置檔案位置 -->
<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- spring核心監聽器 -->
<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- struts核心控制器 -->
<filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>
    <!-- 歡迎頁面 -->
<welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

啟動成功

注意事項：

    struts2 約定要求，將JSP頁面 放入WEB-INF 下

           struts2攔截器，攔截 Action的訪問 

    問題： Filter 和 Interceptor 有何區別？

           Filter可以攔截所有web 資源

           Interceptor 只能攔截Action

<!-- 需要進行許可權控制的頁面訪問 -->

<action name="page_*_*">

<result type="dispatcher">

                /WEB-INF/pages/{1}/{2}.jsp

        </result>

</action>

訪問 page_a_b.action  對映到/WEB-INF/pages/a/b.jsp
