struts2.3.5整合hibernate3.2.0 实例详解

简单用户登录页面struts2整合hibernate3演示步骤：

第一步先加入struts2框架，引入struts2.3.5文档库，

在src 下创建struts.xml 文件

struts.xml文件内容如下：

<?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">

manager.xml文件内容如下

<?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">

<package name="manager" extends="default">

<interceptors>
<interceptor name="loginInterceptor" class="com.hrbkejia.interceptor.LoginInterceptor"/>
</interceptors>


<global-results>
<result name="login" type="redirect">/welcom_UserLogin.action</result>
</global-results>

<action name="welcom_*" class="com.hrbkejia.Action.UserLoginAction" method="{1}">
<result name="login">/WEB-INF/jsp/Login.jsp</result>
<result name="success">/WEB-INF/jsp/maina.jsp</result>
 
 
</action>
</package>

</struts>
创建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>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<base href="<%=basePath%>">

<title>网站后台 - 登录 </title>

<link rel="stylesheet" type="text/css" href="js/jqueryEasyUI132/themes/default/easyui.css">
<link rel="stylesheet" type="text/css" href="js/jqueryEasyUI132/themes/icon.css">
<link rel="stylesheet" type="text/css" href="js/jqueryEasyUI132/demo/demo.css">
<script type="text/javascript" src="js/jqueryEasyUI132/jquery-1.8.0.min.js"></script>
<script type="text/javascript" src="js/jqueryEasyUI132/jquery.easyui.min.js"></script>

</head>

<body>

<div style="font-size: 14px;text-align: center;">网站后台登录</div>
<table width="56%" align="center" border="0" cellpadding="5"
cellspacing="0">
<tr>
<td width="10%" align="right">登录账号：</td>
<td width="20%" align="left">
<input class="easyui-validatebox" type="text" name="userName" data-options="required:true" style="width: 200px" missingMessage="用户名必须填写"/>
</td>
</tr>
<tr>
<td align="right">登录密码：</td>
<td align="left">

<input class="easyui-validatebox" type="password" name="passWord" data-options="required:true" style="width: 200px" missingMessage="密码必须填写"/>
</td>
</tr>
<tr>
<td align="center" colspan="2">
<a href="javascript:void(0)" class="easyui-linkbutton" onclick="submitForm()">登录</a>
<a href="javascript:void(0)" class="easyui-linkbutton" onclick="clearForm()">清除</a>

</tr>
</table>
</form>
</td>
</tr>
<tr>
<td height="29" align="right" valign="bottom">
<div align="center" style="height:20px;">

</div>
</td>
</tr>
</table>
</td>
</tr>
</table>
</td>
</tr>
</table>
</td>
</tr>
</table>
<script>
//登录提交验证
function submitForm(){

$('#loginForm').form('submit', {
url:'welcom_login.action',
onSubmit: function(param){
var isValid = $(this).form('validate'){

return isValid;// return false will stop the form submission
},
success:function(data){
var data = eval('(' + data + ')');
if (data.success){
var indexUrl="welcom_loginSuccess.action";
var appPath ="/"+location.pathname.split("/")[1] +"/";
alert(appPath+ indexUrl);
window.location.href =appPath+ indexUrl;
return;
}else {
$.messager.show({
title:'登录提示',
msg:data.message,
timeout:5000,
showType:'slide'
});
}
}
});
}

//登录输入清除
function clearForm(){
$('#loginForm').form('clear');
}
</script>
</body>

</html>

创建bean类

User类内容如下：

package com.hrbkejia.bean;

public class UserManager {
private String userId;
private String userName;
private String passWord;

public UserManager(){}

public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
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;
}

}
创建hibernate3.2.0 ，引入hibernate3.2.0文档库

在src下加入hibernate.cfg.xml文件

hibernate.cfg.xml文件内容：

<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://××××××××/××××××</property>
<property name="connection.username">root</property>
<property name="connection.password">root</property>
<property name="show_sql">true</property>
<property name="format_sql">true</property>


<mapping resource="com/hrbkejia/bean/User.hbm.xml"/>

</session-factory>
</hibernate-configuration>

在User类同包下，加入User类关系映射文件User.hbm.xml文件内容如下

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>

接下来编写SessionFactory工厂类

HibernateSessionFactory.java文件内容：

package com.hrbkejia.util;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.cfg.Configuration;

public class HibernateSessionFactory {
private static Log log = LogFactory.getLog(HibernateSessionFactory.class);

//Hibernate 默认配置文件路径，此处为classPath
private static String CONFIG_FILE_LOCALTION = "/hibernate.cfg.xml";

//使用ThreadLocal控制Session对象
private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();

private static Configuration configuration = new Configuration();

private static org.hibernate.SessionFactory sessionFactory;

//配置文件路径
private static String configFile = CONFIG_FILE_LOCALTION;

/**
* 获取Session
* @param args
*/
public static Session getSession()throws HibernateException{
//从ThreadLocal中获取已有的Session对象
Session session = (Session)threadLocal.get();
//如果ThreadLocal中不存在session,则重新建立Session对象
if(session == null || !session.isOpen()){
if(sessionFactory == null){
rebuildSessionFactory();
}
session = (sessionFactory != null)?sessionFactory.openSession():null;

//Session对象获取后，植入ThreadLocal中
threadLocal.set(session);
}
return session;
}

/**
* 建立SessionFactory对象
* @param args
*/
public static void rebuildSessionFactory(){
try{
configuration.configure(configFile);
sessionFactory = configuration.buildSessionFactory();

}catch(Exception e){
log.fatal("创建SessionFactory失败");
e.printStackTrace();
}
}

/**
* 关闭Session对象
* @param args
*/
public static void closeSession()throws HibernateException{
Session session = (Session)threadLocal.get();
threadLocal.set(null);
//如果该线程中存在Session对象，则关闭它
if(session != null){
session.close();
}
}

}

添加HibernateCallback.java 类，内容如下：

package com.hrbkejia.util;

import org.hibernate.Session;

public interface HibernateCallback {
public Object doInSession(Session session);
}

添加UserDao接口：

package com.hrbkejia.dao;

import java.util.List;

import com.hrbkejia.bean.UserManager;

public interface UserManagerDao {
public List queryAllUserManager()throws Exception;
public List queryAllUserManager(int startNum, int endNum)throws Exception;
public UserManager queryUserManager(final UserManager userManager)throws Exception;
public boolean saveUserManager(UserManager userManager)throws Exception;
}

添加UserDaoImpl类

package com.hrbkejia.dao.impl;

import java.util.ArrayList;
import java.util.List;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

import com.hrbkejia.bean.UserManager;
import com.hrbkejia.dao.UserManagerDao;
import com.hrbkejia.util.HibernateCallback;
import com.hrbkejia.util.HibernateSessionFactory;

public class UserManagerDaoImpl implements UserManagerDao{

private Object execute(HibernateCallback action)throws Exception{
Object ret = null;
Session session = HibernateSessionFactory.getSession();

// 定义事务Transaction对象
Transaction tx = null;
try {
tx = session.beginTransaction();

ret = action.doInSession(session);

tx.commit();
} catch (Exception e) {
if (tx != null) {
tx.rollback();
}
throw e;
} finally {
session.close();
}
return ret;
}
/**
* 按照用户名和密码查询登录用户实例
*/
public UserManager queryUserManager(final UserManager userManager) throws Exception {

return (UserManager)execute(new HibernateCallback(){
public Object doInSession(Session session) {
Query query =
session.createQuery
("from com.hrbkejia.bean.UserManager as user where user.userName=? and user.passWord=?");
query.setString(0, userManager.getUserName());
query.setString(1, userManager.getPassWord());
List list = query.list();
if(list != null && list.size() >= 1){
return list.get(0);
}
return null;
}
});

}

public static void main(String [] args){
UserManagerDaoImpl s = new UserManagerDaoImpl();
UserManager userManager = new UserManager();
userManager.setUserName("adming");
userManager.setPassWord("admin");
try {
//s.saveUserManager(userManager);
UserManager u = (UserManager)s.queryUserManager(userManager);
System.out.println(u.getUserName());

} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

public boolean saveUserManager(final UserManager userManager) throws Exception {
// TODO Auto-generated method stub

execute(new HibernateCallback(){
public Object doInSession(Session session) {
session.save(userManager);
return true;
}
});
return false;
}

public List queryAllUserManager(UserManager userManager) throws Exception {
// TODO Auto-generated method stub
return null;
}
public List queryAllUserManager() throws Exception {
// TODO Auto-generated method stub
return null;
}
public List queryAllUserManager(int startNum, int endNum) throws Exception {
// TODO Auto-generated method stub
return null;
}

}

添加ManagerSupport.java类

package com.hrbkejia.Action;

import com.opensymphony.xwork2.ActionSupport;

public class ManagerSupport extends ActionSupport{

}

添加UserAction类：

package com.hrbkejia.Action;

import java.io.PrintWriter;
import java.util.UUID;

import org.apache.struts2.ServletActionContext;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.json.simple.JSONObject;

import com.hrbkejia.bean.UserManager;
import com.hrbkejia.dao.UserManagerDao;
import com.hrbkejia.dao.impl.UserManagerDaoImpl;
import com.opensymphony.xwork2.ModelDriven;

public class UserLoginAction extends ManagerSupport implements ModelDriven<UserManager>{

private UserManagerDao userManagerDao = new UserManagerDaoImpl();

private UserManager userManager = new UserManager();

public UserManager getModel() {

return userManager;
}

/**
* 返回到登录页面
* @return 登录
* @throws Exception
*/
public String UserLogin() throws Exception {

return this.LOGIN;
}

/**
* 使用jquery 登录输入验证
* @throws Exception
*/
public void login() throws Exception{
System.out.println("-----1------");

ServletActionContext.getResponse().setCharacterEncoding("UTF-8"); //防止jsp页面乱码
ServletActionContext.getResponse().setContentType("text/html;charset=UTF-8"); //防止jsp页面乱码

System.out.println("-----2------");
JSONObject json = new JSONObject();
System.out.println("-----3------");
PrintWriter writer = null;
writer = ServletActionContext.getResponse().getWriter();
System.out.println("-----2------");
String userName = getModel().getUserName();
String passWord = getModel().getPassWord();
System.out.println("-----3------");

if((userName == null || userName.trim().equals("")) ||
(passWord == null || passWord.trim().equals(""))){
System.out.println("-----4------");
try{

json.put("success", false);
json.put("message", "请检查用户名和密码是否填写了？");
System.out.println(json);
writer.print(json);
}catch(Exception e){
e.printStackTrace();
}finally {
if(writer != null){
writer.close();
}
}
return ;
}

UserManager user = userManagerDao.queryUserManager(getModel());
if(user == null){
System.out.println("-----5------");
try{
System.out.println("userName="+userName);

json.put("success", false);
json.put("message", "用户名或密码错误，请重新登录！");
System.out.println(json);
writer.print(json);
}catch(Exception e){
e.printStackTrace();
}finally {
if(writer != null){
writer.close();
}
}
}else {
System.out.println("-----6------");
try{
System.out.println("登录成工userName="+userName);
ServletActionContext.getContext().getSession().put("user", user);
json.put("success", true);
writer.print(json);
}catch(Exception e){
e.printStackTrace();
}finally {
if(writer != null){
writer.close();
}
}
}
}

/**
* 成功页面
* @return
* @throws Exception
*/
public String loginSuccess()throws Exception{
if(ServletActionContext.getContext().getSession().get("user") == null){
return this.LOGIN;
}
return this.SUCCESS;
}
}
