|--spring-tx-4.3.2.RELEASE.jar
2.配置框架文件
bean.xml
hibernate.cfg.xml（或省略）
3.搭建环境
1）编写实体类Dept.java
public class Dept { private int id; private String name; 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; } }
2）编写对应的Dept.hbm.xml
<?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 package="cn.itcast.entity"> <class name="Dept" table="t_dept"> <id name="id" column="deptId"> <generator class="native"></generator> </id> <property name="name" column="deptName"></property> </class> </hibernate-mapping>
3）编写DeptDao.java
public class DeptDao { // Spring与Hibernate整合： IOC容器注入 private SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } // 保存一个记录 // Spring与Hibernate整合：事务管理交给Spring public void save(Dept dept) { sessionFactory.getCurrentSession().save(dept); } }
4）编写DeptService.java
public class DeptService { private DeptDao deptDao; public void setDeptDao(DeptDao deptDao) { this.deptDao = deptDao; } public void save(Dept dept){ deptDao.save(dept); } }
5）编写测试类App.java
public class App { // 容器 private ApplicationContext ac = new ClassPathXmlApplicationContext("bean.xml"); @Test public void testApp() throws Exception { DeptService deptServie = (DeptService) ac.getBean("deptService"); System.out.println(deptServie.getClass()); deptServie.save(new Dept()); } }
6）配置bean.xml
<?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" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 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.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- dao 实例 --> <bean id="deptDao" class="包名.DeptDao"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- service 实例 --> <bean id="deptService" class="包名.DeptService"> <property name="deptDao" ref="deptDao"></property> </bean> <!-- 数据源配置 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver"></property> <property name="jdbcUrl" value="jdbc:mysql:///hib_demo"></property> <property name="user" value="root"></property> <property name="password" value="root"></property> <property name="initialPoolSize" value="3"></property> <property name="maxPoolSize" value="10"></property> <property name="maxStatements" value="100"></property> <property name="acquireIncrement" value="2"></property> </bean> <!-- ###########Spring与Hibernate整合 start########### --> <!-- 方式（1）直接加载hibernate.cfg.xml文件的方式整合 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> </bean>
