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，

struts2.3.5整合hibernate3.2.0 实例详解_hibernate

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">

</package>

</struts>

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">

</interceptors>

<global-results>

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

</global-results>

<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>

<!--

</head>

<body>

<tr>

<tablewidth="100%" height="100%" border="0" cellpadding="0" cellspacing="0">

//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

struts2.3.5整合hibernate3.2.0 实例详解_java_02

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>

</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>

</id>

</class>

</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;

}
