配置Struts2的过程(样例)

you23hai45 分享于 2013-06-30

推荐:Struts2配置

 通常struts2加载struts2常量的顺序如下:   1. struts-default.xml:该文件保存在struts2-core-2.0.6.jar文件中。 2. struts-plugin.xml:该文件保存在struts2

1、首先,打开MyEclipse开发软件,新建一个Web Project,命名struts2;


2、配置Tomcat服务器



3、配置server.xml

server.xml:

<?xml version='1.0' encoding='utf-8'?>

     define subcomponents such as "Valves" at this level.
     Documentation at /docs/config/server.html

  <!-- A "Service" is a collection of one or more "Connectors" that share

    <!-- A "Connector" represents an endpoint by which requests are received

       <Context path="/struts2" docBase="D:\MyEclipse\workspace\struts2\WebRoot" reloadable="true"/>

      </Host>
    </Engine>
  </Service>
</Server>


4、打开struts2,在WebContent目录下新建一个login.jsp文件,源码如下:

login.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
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>登录界面</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<style type="text/css">
	 fieldset{
	      font-size: 12px;
	      font-weight: bold;
	      background-color: #807989;
	      text-align: center;
	      width:240px;
	      height: 100px;
	 }
	    form{
	      font-size:12px;
	      text-align:center;
	      background-color: #CCCCCC;
	      width:240px;
	      height: 90px;
	    }
	</style>

  </head>
  
  <body>
   <center>
    <fieldset>
         <legend>登录界面</legend>
         <form action="login.action" method="post">
                       用户名:<input type="text" name="username" id="username" value=""/><br/>
                       密  码:<input type="password" name="password" id="password" value=""/><br/>
         <input type="submit" name="submit" value="提交">   
         <input type="reset" name="reset" value="重置">
     </form>
    </fieldset>
   </center>
  </body>
</html>

5、配置web.xml

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">
	
<struts>
  <!-- 配置名为login的Action -->
  <package name="struts2" extends="struts-default">
        <action name="login" class="com.you.struts.LoginAction">
               <result name="success">/result.jsp</result>
        </action>
  </package>
</struts>

6、导入struts2夹包


推荐:Struts2的配置方法

一、本文适用者      本文适合刚开始接触struts2的用户,本文即教用户如何跑一个类似hello world 程序。 二、开发环境      操作系统:window xp sp2      开发

7、在src目录下新建一个包,并在该包下创建一个LoginAction类和struts.xml文件


8、编写LoginAction,它的源文件如下:

LoginAction.java:

/**
 * @Title:LoginAction.java
 * @Package:com.you.struts
 * @Description:登录的Action
 * @author:Youhaidong(游海东)
 * @date:2013-6-30 上午12:01:36
 * @version V1.0
 */
package com.you.struts;

/**
 * 类功能说明
 * 类修改者 修改日期
 * 修改说明
 * <p>Title:LoginAction.java</p>
 * <p>Description:游海东个人开发</p>
 * <p>Copyright:Copyright(c)2013</p>
 * @author:游海东
 * @date:2013-6-30 上午12:01:36
 * @version V1.0
 */
public class LoginAction {
	
	//用户名
	private String username;
	//密码
	private String password;
	
	/**
	 * execute方法
	 * @Title:execute
	 * @Description:execute
	 * @param:@return
	 * @param:@throws Exception
	 * @return:String
	 * @throws
	 */
	public String execute() throws Exception{
		return "success";
	}

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

}

9、配置struts.xml

struts.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">
	
<struts>
  <!-- 配置名为login的Action -->
  <package name="struts2" extends="struts-default">
        <action name="login" class="com.you.struts.LoginAction">
               <result name="success">/result.jsp</result>
        </action>
  </package>
</struts>

10、再次在WebContent目录下新建一个返回结果的result.jsp文件

result.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
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>返回结果界面</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<style type="text/css">
	   table{
	      font-size: 12px;
	      background-color: #A2BCD8;
	      border:1px solid #E8F2FE;
	   }
	   label{
	      font-size: 12px;
	      font-weight: bold;
	   }
	</style>

  </head>
  
  <body>
     <table>
        <tr>
          <td>
            <label>用户名:${requestScope.username}</label> <br>
            <label>密  码:${requestScope.password}</label>
          </td>
        </tr>
     </table>       
  </body>
</html>

11、运行Tomcat,在浏览器地址栏输入: http://localhost:8080/struts2/login.jsp

(1)按回车键,会显示如下图:


(2)输入用户名和密码后,点击“提交”,会跳到:http://localhost:8080/struts2/login.action
