数据库loginusers表
1、新建javaWeb Porject项目spring_hibernate,添加com.dao包(放置数据库操作类)、com.pojo包(放置hibernate生成的POJO类)
2、右击项目添加spring开发功能，注意这里需把spring Persistence类库勾选
3、接下来是添加hibernate组件，与单独部署时不同的是这里不生成hibernate.cfg.xml文件，而是将数据库配置当成bean,
分配id值，统一交由spring进行配置管理
4、配置映射数据库表生成POJO类，com.pojo包如下
package com.pojo;
/**
* AbstractLoginusers entity provides the base persistence definition of the Loginusers entity. @author MyEclipse Persistence Tools
*/
public abstract class AbstractLoginusers implements java.io.Serializable {
// Fields
private Integer id;
private String userName;
private String password;
// Constructors
/** default constructor */
public AbstractLoginusers() {
}
/** minimal constructor */
public AbstractLoginusers(Integer id) {
this.id = id;
}
/** full constructor */
public AbstractLoginusers(Integer id, String userName, String password) {
this.id = id;
this.userName = userName;
this.password = password;
}
// Property accessors
public Integer getId() {
return this.id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUserName() {
return this.userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return this.password;
}
public void setPassword(String password) {
this.password = password;
}
}package com.pojo;
/**
* Loginusers entity. @author MyEclipse Persistence Tools
*/
public class Loginusers extends AbstractLoginusers implements java.io.Serializable {
// Constructors
/** default constructor */
public Loginusers() {
}
/** minimal constructor */
public Loginusers(Integer id) {
super(id);
}
/** full constructor */
public Loginusers(Integer id, String userName, String password) {
super(id, userName, password);
}
}
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!--

<hibernate-mapping>
<class name="com.pojo.Loginusers" table="loginusers" catalog="mydb">

<column name="userName" />
</property>
<property name="password" type="java.lang.String">
<column name="password" />
</property>
</class>
</hibernate-mapping>
5、在WebRoot下新建、编写login.jsp登录主页
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>spring Hibernate login</title>
</head>
<body>
<h3>User Login</h3>
<form action="validate.jsp" method="post">
<label>Account: </label>
<input type="text" name="userName"/><br>
<label>Password:</label>
<input type="password" name="password"/><br><br>
<input type="reset" value="reset"/>
<input type="submit" value="submit"/>
</form>
</body>
</html>
6、在持久层com.dao包下编写数据库操作类完成BaseDao基类(提供SessionFactory获取Session)、InterUserDao接口类、
UserDaoImpl接口实现类，实现用户验证
package com.dao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
public class BaseDao {
//Dao持久层访问SessionFactor获取session对象的中间组件
//解耦Dao层与SessionFactory
private SessionFactory sessionFactory;
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public Session getSession(){
Session session=sessionFactory.openSession();
return session;
}
}
package com.dao;
import com.pojo.Loginusers;
public interface InterUserDao {
public Loginusers validate(String name,String password); //提供数据库操作方法：验证用户名密码
}
package com.dao;
import java.util.Iterator;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import com.pojo.Loginusers;
public class UserDaoImpl extends BaseDao implements InterUserDao {
@Override
public Loginusers validate(String name,String password) {
// TODO Auto-generated method stub
Session session=getSession(); //从BaseDao继承的方法中得到session
Query query=session.createQuery("from Loginusers where userName=? and password=?");
query.setParameter(0, name);
query.setParameter(1, password);
List list=query.list();
Iterator it=list.iterator();
while(it.hasNext()){
if(list.size()!=0){
Loginusers user=(Loginusers)it.next();//创建持久化对象
return user;
}
}
session.close();
return null;
}
}
7、修改applicationContext.xml文件添加BaseDao、UserDaoImpl的bean组件,在数据库配置bean中没有
数据库驱动DriverClass属性需手动添加。完成如下
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd" xmlns:tx="http://www.springframework.org/schema/tx">
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource">
<!-- 配置数据库驱动 -->
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://localhost:3306/"></property>
<property name="username" value="root"></property>
<property name="password" value="root123"></property>
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>com/pojo/Loginusers.hbm.xml</value>
</list>
</property>
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="baseDao" class="com.dao.BaseDao">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
<bean id="userDaoImpl" class="com.dao.UserDaoImpl" lazy-init="false" parent="baseDao"></bean>
<tx:annotation-driven transaction-manager="transactionManager" />
</beans>
8、在WebRoot下新建编写validate.jsp完成验证业务
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%@ page import="org.springframework.context.*,org.springframework.context.support.*" %>
<%@ page import="com.dao.*,com.pojo.*" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>验证业务方法</title>
</head>
<body>
<%
request.setCharacterEncoding("utf-8");
String name=request.getParameter("userName");
String password=request.getParameter("password");
boolean flag=false; //验证标识符
Loginusers user=null;
user=(Loginusers)session.getAttribute("user");
if(user==null){ //判断第一次登录
ApplicationContext context=new FileSystemXmlApplicationContext(
"file:D:/JAVA-Develop/Workspaces/MyEclipse 2017 CI/spring_hibernate/src/applicationContext.xml");
InterUserDao interUserDao=(InterUserDao)context.getBean("userDaoImpl");
user=interUserDao.validate(name,password);
if(user!=null){
session.setAttribute("user",user);//保存user对象
flag=true;
}
}else{
flag=true;
}
if(flag)
response.sendRedirect("success.jsp");
else
response.sendRedirect("error.jsp");
%>
</body>
</html>
9、在WebRoot下编写success.jsp成功页、error.jsp失败页
<%@ page language="java" import="java.util.*" import="com.pojo.Loginusers" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title> success login</title>
</head>
<body>
<%
Loginusers user=(Loginusers)session.getAttribute("user");
System.out.print(user);
String uName=user.getUserName();
%>
<h2 style="text-align:center;margin:200xp auto">Welcome <%=uName %>,Login Success</h2>
</body>
</html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title> error login </title>
</head>
<body>
<h2 style="text-align:center;margin:100px auto">Login Error</h2>
</body>
</html>
10、保存启动Tomcat，浏览器测试
