sPRing與hibernate的整合目的就是為了讓 IOC 容器來管理 Hibernate 的核心接口sessionFactory以及讓 Hibernate 使用上 Spring 的聲明式事務(wù)來進行事務(wù)操作. spring整合hibernate 有兩種方式 1、注解方式 2、xml方式實現(xiàn) 1、注解方式實現(xiàn)： applicationContext.xml配置文件：
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="Oracle.jdbc.driver.OracleDriver"></property> <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:XE"></property> <property name="username" value="iotek"></property> <property name="passWord" value="iotek"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="packagesToScan" value="com.iotek.bean"></property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> </props> </property> </bean> <bean id="person" class="com.iotek.daoImpl.PersonImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> </beans>2.xml方式實現(xiàn) applicationContext.xml配置：
<?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:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd"> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property> <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:XE"></property> <property name="username" value="iotek"></property> <property name="password" value="iotek"></property> </bean> <!-- session:::sessionFactory 相當(dāng)于 hibernate.cfg.xml --> <!-- 配置SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="mappingResources"> <list> <value>com/iotek/bean/person.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> </props> </property> </bean> <bean id="person" class="com.iotek.daoImpl.PersonImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> </beans>兩種配置最大的區(qū)別就是注解方式不用在寫O/R映射配置文件而xml方式實現(xiàn)的要配置O/R映射配置文件 采用注解的方式是：（掃描指定的包）
<property name="packagesToScan" value="com.iotek.bean"></property>采用xml方式是：（配置**.hbm.xml文件）
<property name="mappingResources"> <list> <value>com/iotek/bean/person.hbm.xml</value> </list> </property>實體類
package com.iotek.bean;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;@Entitypublic class Person {@Id@GeneratedValue(strategy=GenerationType.AUTO)private int id;@Column(length=11)private String name;private int age;public int getId() { return id;}public void setId(int id) { this.id = id;}public String getName() { return name;}public void setName(String name) { this.name = name;}public int getAge() { return age;}public void setAge(int age) { this.age = age;}}package com.iotek.daoImpl;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.springframework.beans.factory.annotation.Autowired;import com.iotek.bean.Person;import com.iotek.dao.PersonDao;public class PersonImpl implements PersonDao { /*@Autowired*/ private SessionFactory sessionFactory; public SessionFactory getSessionFactory() { return sessionFactory; } public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } @Override public void savePerson(Person p) { Session session = sessionFactory.openSession(); if(session==null){ System.out.println("null"); }else{ System.out.println("not null"); } Transaction tran = null; try{ System.out.println(p.getName()); tran = session.beginTransaction(); session.save(p); tran.commit(); System.out.println("提交"); }catch(Exception e){ tran.rollback(); }finally{ session.close(); } }}測試類：
package com.iotek.demo;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.iotek.bean.Person;import com.iotek.dao.PersonDao;import com.iotek.daoImpl.PersonImpl;public class Demo { public static void main(String[] args) { // TODO Auto-generated method stub ApplicationContext context =new ClassPathXmlApplicationContext("applicationContext.xml"); PersonImpl person=context.getBean("person", PersonImpl.class); Person p = new Person(); p.setId(10); p.setName("xiaoming"); p.setAge(22); person.savePerson(p); System.out.println("成功"); }}通過.properties文件寫入驅(qū)動，賬號等信息（jdbc.properties）
