来源：互联网发布：大话设计模式java pdf 编辑：程序博客网时间：2024/06/05 19:39

Struts2资源包下载：http://struts.apache.org/

开发环境：

DB:MySQL5.0.67

Server:Tomcat6

IDE:MyEclipse6.5

开发步骤：

1.创建Web工程

2.添加Struts2所必须的架包(5个)：

Commons-logging-1.0.4.jar

freemarker-2.3.8.jar

ognl-2.6.11.jar

struts2-core-2.0.11.jar

xwork-2.0.4.jar

3.配置web.xml文件，添加Struts2过滤器：

<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>

4.编写LoginAction.java(Struts2的action)

在实际开发中action类继承ActionSupport

5.添加并配置Struts2的struts.xml配置文件(在src下创建)：

<?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>

<package name="struts2" extends="struts-default">

<action name="login" class="com.xyls.action.LoginAction">

<result name="success">/welcome.jsp</result>

</action>

</package>

</struts>

6.创建jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s" %>
<%
String path = request.getContextPath();
//System.out.println(path);
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <base href="<%=basePath%>">

    <title>My JSP 'login.jsp' starting page</title>
</head>

<body>
<center><h1>登录页面</h1>
     <form action="<%=path %>/xyls/login.action" method="post">
     <table>
       <tr>
        <td><label for="name">用户名:</label>
        <td><input type="text" id="name" name="username">
       <tr>
        <td><label for="pwd">密码:</label>
        <td><input type="password" id="pwd" name="password">
       <tr>
        <td><input type="submit" value="提交">
        <td><input type="reset" value="重置">
      </table>

     </form>
    </center>

    <s:form action="xyls/login.action">
    <s:textfield name="username" label="用户名"/>
    <s:password name="password" label="密码"/>
    <s:submit value="提交"/>
    </s:form>
</body>
</html>

7.部署、启动Tomcat6服务器，测试Struts2流程是否添加成功。
