struts2的学习之

struts2学习的简单实例

web.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
 http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

 <filter>
  <filter-name>struts2</filter-name>
  <filter-class>
   org.apache.struts2.dispatcher.FilterDispatcher
  </filter-class>
 </filter>
 <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>
</web-app>
只需配置一个FilterDispatcher的过滤器而已

 

 

在struts.xml类似Struts1.2中的struts-config.xml配置文件信息

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
  <include file="struts-default.xml"/>
  <constant name="struts.devMode" value="false"/>
  <constant name="struts.enable.DynamicMethodInvocation" value="false"/>
   <package name="struts2"  extends="struts-default">
  
  
     <action name="HelloWord" class="cn.com.unutrip.struts2.HelloWord">

       <result name="error">/error.jsp</result>

    <action name="Timer" class="cn.com.unutrip.struts2.TimerInterceptorAction">
       <interceptor-ref name="timer"/>
       <result>/timer.jsp</result>
    </action>
   </package>
</struts>
