struts2 实例 demo 源码登录

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 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

<%@ 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

<%@ 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

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

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

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 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:

Horse_Chasing 写道

我完全下载您的代码，放在我本地，发现报404错误，该怎么办？

注意在浏览器里面输入的路径.是否与web.xml和structs.xml路径对应.

struts2路径匹配,struts.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>
	<constant name="struts.devMode" value="true" />
	<!-- 改变url现实的后缀,默认是action -->
    <constant name="struts.action.extension" value="xhtml" />
    
    <!-- http://localhost:8080/struts2login/user/UserLogin.xhtml -->
	<package name="user" extends="struts-default" namespace="/user" >	
	    <!-- 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>
	
	<!-- http://localhost:8080/struts2login/front/index.xhtml -->
	<package name="front" extends="struts-default" namespace="/front" >	
	    <!-- 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="index">
			<result name="success" >/index.jsp</result>	
			<!-- name="success"
			<result>/index.jsp</result>	
			-->
		</action>				
	</package>
	
	
	<!-- http://localhost:8080/struts2login/front/ssssllll/sssss/s/sss/index.xhtml -->
	<package name="main" extends="struts-default" namespace="" >	
	    <!-- 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="index">
			<result name="success" >/index2.jsp</result>	
			<!-- name="success"
			<result>/index.jsp</result>	
			-->
		</action>				
	</package>
</struts>
