struts-入门登陆 maven 构建

接触到别人的新的项目, 不得不研究下Struts2了. 用struts2写了一个登录例子, 大致了解了一下.

1. web.xml代码:

   Xml代码  
   
  
 <?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">  
       
     <!-- 配置struts2的过滤器 -->  
     <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>  
       
     <welcome-file-list>  
         <welcome-file>login.jsp</welcome-file>  
     </welcome-file-list>  
 </web-app>  

2.登录页面login.jsp

   Html代码  
   
  
 <%@ page pageEncoding="utf-8"%>  
 <%@ taglib prefix="s" uri="/struts-tags" %>  
   
 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">  
 <html>  
   <head>      
     <title>Struts2 Person Login Test</title>  
   </head>  
     
   <body>  
     <s:form action="UserLogin">  
         <s:textfield name="per.username" label="username"></s:textfield>  
         <s:password name="per.password" label="password"></s:password>  
         <s:submit></s:submit>  
     </s:form>  
   </body>  
 </html>  

3.登录成功页面login_s.jsp

   Html代码  
   
  
 <%@ page language="java"  pageEncoding="UTF-8"%>  
 <%  
 String path = request.getContextPath();  
 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";  
 String username = (String)session.getAttribute("user");  
 %>  
   
 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">  
 <html>  
   <head>  
     <base href="<%=basePath%>">  
     <title>Struts2 Person Login Result</title>  
   </head>  
     
   <body>  
     Hi:<br>  
     <%=username%><br>  
     Welcome... <br>  
   </body>  
 </html>  

4. Action代码PersonAction.java

   Java代码  
   
  
 package com.greatwqs.action;  
   
 import java.util.Map;  
   
 import com.greatwqs.dao.PersonDao;  
 import com.greatwqs.entity.Person;  
 import com.opensymphony.xwork2.ActionContext;  
 import com.opensymphony.xwork2.ActionSupport;  
 /*** 
  *  
  * @author greatwqs.iteye.com 
  * @data 2011-12-01 
  */  
 public class PersonAction extends ActionSupport {  
   
     private Person per;  
   
     private static final long serialVersionUID = 1L;  
   
     public String execute() throws Exception {  
         PersonDao dao = new PersonDao();  
         boolean flag = dao.isPersonCanLogin(per.getUsername(), per.getPassword());  
         if(flag){  
             Map session=(Map)ActionContext.getContext().get(ActionContext.SESSION);  
             session.put("user", per.getUsername());  
             return SUCCESS;  
         } else {  
             return INPUT;  
         }  
     }  
   
     public Person getPer() {  
         return per;  
     }  
   
     public void setPer(Person per) {  
         this.per = per;  
     }  
 }  

5. 实体代码Person.java

   Java代码  
   
  
 package com.greatwqs.entity;  
 /*** 
  *  
  * @author greatwqs.iteye.com 
  * @data 2011-12-01 
  */  
 public class Person {  
   
     private String username;  
       
     private String password;  
   
     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;  
     }     
 }  

6. 数据库持久层代码PersonDao.java

   Java代码  
   
  
 package com.greatwqs.dao;  
 /*** 
  *  
  * @author greatwqs.iteye.com 
  * @data 2011-12-01 
  */  
 public class PersonDao {  
   
     /*** 
      * 根据用户名和密码,判断用户是否能登陆! 
      * @param username 
      * @param password 
      * @return 
      */  
     public boolean isPersonCanLogin(String username, String password) {  
         return username.equals(password);  
     }  
 }  

7. struts.xml

   Xml代码  
   
  
 <?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>  
     <!-- 改变url现实的后缀,默认是action -->  
     <constant name="struts.action.extension" value="xhtml" />  
       
     <package name="struts2login" extends="struts-default">  
         <!-- 这里的Class是由Spring里面制定的ID,如果单独用struts2,则这里是包名+类名 -->  
         <action name="UserLogin" class="com.greatwqs.action.PersonAction">  
             <result name="success" >/login_s.jsp</result>  
             <result name="input">/login.jsp</result>  
         </action>       
     </package>  
 </struts>  

保存起,后面再接触这个,再翻翻!

classpath:

   Xml代码

     <classpathentry kind="src" path="src"/>  
     <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
