spring4和hibernate4.0.0的整合

1.在myeclipse以下创建一个javaproject或者webproject，我创建的时webproject，用的myeclipse2013

2.导入spring的依赖包

3.导入hibernate的依赖包

 

4.在src文件夹以下配置hibernate的核心文件hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>

        <!-- Database connection settings -->
        <property name="connection.driver_class">org.gjt.mm.mysql.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/test</property>
        <property name="connection.username">root</property>
        <property name="connection.password">root</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <!-- <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> -->

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">update</property>

        <mapping resource="org/hibernate/domain/Event.hbm.xml"/>
        <!-- annotation的配置方式 -->
        <mapping class="org.hibernate.domain.Teacher"/>

    </session-factory>

</hibernate-configuration>

5.在WEB-INFO文件夹以下配置spring的核心配置文件applicationContext

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd">
 <!-- <bean id="..." class="..."> collaborators and configuration for this
  bean go here </bean> <bean id="..." class="..."> collaborators and configuration
  for this bean go here </bean> more bean definitions go here -->
 <!-- 配置sessionFactory -->

 <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
  <property name="configLocation">
   <value>classpath:hibernate.cfg.xml</value>
  </property>
 </bean>

 <bean id="DaoImp" class="com.persistent.DaoImp">
  <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>

 

</beans>

6.编写持久化类

package org.hibernate.domain;

import javax.persistence.Entity;
import javax.persistence.Id;
//定义一个实体类
@Entity
public class Teacher {

 private int id;//id
 private String title;//职场
 private String name;//姓名
 //定义一个主键
 @Id
 public int getId() {
  return id;
 }
 public void setId(int id) {
  this.id = id;
 }
 public String getTitle() {
  return title;
 }
 public void setTitle(String title) {
  this.title = title;
 }
 public String getName() {
  return name;
 }
 public void setName(String name) {
  this.name = name;
 }
 
}

7.编写保存之久话的类和方法

package com.persistent;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.domain.Teacher;

public class DaoImp {

 private SessionFactory sessionFactory;
 
 public SessionFactory getSessionFactory() {
  return sessionFactory;
 }

 public void setSessionFactory(SessionFactory sessionFactory) {
  this.sessionFactory = sessionFactory;
 }

 public void save(){
  Session session=sessionFactory.getCurrentSession();
  session.beginTransaction();
        Teacher teacher = new Teacher();
        teacher.setId(6);
        teacher.setName("hibernate!!");
        teacher.setTitle("we will");
        session.save(teacher);//利用annotation进行插入操作
        session.getTransaction().commit();
 }
}

8.在hibernate.cfg.xml文件里配置

 <!-- annotation的配置方式 -->
        <mapping class="org.hibernate.domain.Teacher"/>

9.进行測试

package com.demo.test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

import com.persistent.DaoImp;

public class TestMain2 {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  
      
  
 
  
  ApplicationContext context =
       new FileSystemXmlApplicationContext("WebRoot/WEB-INF/applicationContext.xml");
        /*Hello hello=(Hello) context.getBean("hello");
        hello.display();*/
  DaoImp di = (DaoImp)context.getBean("DaoImp");
  di.save();
  
 }

}

10.能够看查看数据库，已经有数据了，控制台也打印出了sql语句
