Struts2 示例

Struts2必须的jar包

目录结构

配置文件

1.web.xml

(新建web项目时，点击next，到Web Module页勾选底部的Generate Web.xml deployment descriptor ，可自动生成；位置在WEB-INF下)

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns="http://java.sun.com/xml/ns/javaee" 
   xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
   http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
   id="WebApp_ID" version="3.0">
   
   <display-name>Struts 2</display-name>

   <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>
   
   <welcome-file-list>
      <welcome-file>index.jsp</welcome-file>
   </welcome-file-list>
</web-app>

2.struts.xml

（WebContent/WEB-INF/classes 的文件夹下，Eclipse并没有默认创建“classes”文件夹，需要自己创建）

<?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>
<constant name="struts.devMode" value="true" />
   <package name="helloworld" extends="struts-default">
     
      <action name="hello" 
            class="com.zhang.struts2.HelloWorldAction" 
            method="execute">
            <result name="success">/HelloWorld.jsp</result>
      </action>
   </package>
</struts>

创建Aciton类

3. HelloWorldAction.java

package com.zhang.struts2;

public class HelloWorldAction{
       private String name;

       public String execute() throws Exception {
          return "success";
       }
       
       public String getName() {
          return name;
       }

       public void setName(String name) {
          this.name = name;
       }
    }

界面文件

      <input type="text" name="name"/>
      <input type="submit" value="Say Hello"/>
   </form>
