步骤1：新建web project项目Struts2Demo

步骤2：导入struts2所需要的jar包

步骤3：在src下新建struts2核心配置文件struts.xml

   
   	
    		
     			
      
       /WEB-INF/jsp/user/login.jsp
      		
     				
     			
      
       /WEB-INF/jsp/user/loginSuccess.jsp
      			
      
       /WEB-INF/jsp/user/loginFailure.jsp
      		
     			
    
   

步骤4：新建包com.cn.vo,并在该包下新建实体类UserVO

package com.cn.vo;public class UserVO {	private int id;	private String username;	private String password;	public int getId() {		return id;	}	public void setId(int id) {		this.id = id;	}	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;	}}

步骤5：新建包com.cn.action，并在该包下新建控制器类LoginAction

package com.cn.action;import com.cn.vo.UserVO;public class LoginAction {	private UserVO userVO;		/**	 * 登录跳转	 * */	public String login(){		return "loginStr";	}		/**	 * 登录处理	 * */	public String toLogin(){		String username=userVO.getUsername()!=null ? userVO.getUsername():"";		String password=userVO.getPassword()!=null?userVO.getPassword():"";		if("admin".equals(username) && "123456".equals(password)){			return "loginSucc";		}else{			return "loginFail";		}	}	public UserVO getUserVO() {		return userVO;	}	public void setUserVO(UserVO userVO) {		this.userVO = userVO;	}		}

步骤6：在WEB-INF下新建文件夹jsp，然后在jsp文件下新建user文件,然后在user文件下新建三个视图

登录视图：login.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%>                  	
   	
   	
       	
   	
   	
             
   
    	
    
    		     
      
    			       
用户名：
    			       
    				    			
    		      
    		      
    			       
密  码：
    			       
    				    			
    		      
    		      
    			       
    				    			
    		      
    	     
    
    
   
  

登录成功跳转视图：loginSuccess.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ taglib prefix="s" uri="/struts-tags" %><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%>                  	
   	
   	
       	
   	
   	
             登录成功,欢迎您${userVO.username}  

登录失败跳转视图：loginFailure.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%>                  	
   	
   	
       	
   	
   	
              登录失败,错误的用户名${userVO.username}
     返回  

步骤7：在web.xml中配置struts2的核心过滤器Struts

   
     
    	  
        
     
      index.jsp
       
      
      
      	
     
      struts2
       	
     
      org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
       
      
      	
     
      struts2
       	
     
      *.action
       
    
   

步骤8：测试

在浏览器地址栏中输入：http://localhost:8080/Struts2Demo/loginAction.action测试

注：上面的struts2配置为最 基本的配置，实际开发中struts.xml配置用通配符进行配置
