Spring结合Hibernate实现数据库事务性操作范例

一、Vo（User.java）

package cn.edu.shnu.Vo;public class User {private Integer id;private String name;private Integer age;public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}二、Vo与数据库表的映射文件(User.hbm.xml)<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><hibernate-mapping>    <class name="cn.edu.shnu.Vo.User" table="user" catalog="test">        <id name="id" type="java.lang.Integer">            <column name="id" />            <generator class="native"></generator>        </id>        <property name="name" type="java.lang.String">            <column name="name" />        </property>        <propery name="age" column="age" />              </class></hibernate-mapping>三、IUserDAO接口(IUserDAO.java)package cn.edu.shnu.impl;public class IUserDAO {    public void insert(User user);    public User find(Integer id);}四、(UserDAO.java) 实现上面的接口package cn.edu.shnu.Daoimport org.hibernate.SessionFactory;import org.springframework.orm.hibernate3.HibernateTemplate;public class UserDAO implements IUserDAO {    private HibernateTemplate hibernateTemplate;    public void setSessionFactory(SessionFactory sessionFactory){        hibernateTemplate = new HibernateTemplate(sessionFactory);    }    public void insert(User user){        hibernateTemplate.save(user);    }    public User find(Integer id){        User user = ()hibernateTemplate.get(User.class, id);        return user;    }}五、(beans-config.xml)配置文件<?xml version="1.0" encoding="utf-8"?><beans xmlns="http://www.springframework.org/schema/beans"  xmlns:xsl="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">    <bean id="dataSource" class="org.springframework.jdbc.dataSource.DriverManagerDataSource">       <property name="driverClassName" value="com.mysql.jdbc.Driver" />       <property name="url" value="jdbc:mysql://localhost:3306/yourDBName" />       <property name="username" value="root" />       <property name="password" value="123456" />    </bean>    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" destroy-method="close">       <property name="dataSource" ref="dataSource" />       <property name="mappingResources">           <list>               <value>cn/edu/shnu/Vo/User.hbm.xml</value>           </list>       </property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop></props></property>   </bean>   <bean id="userDAO" class="cn.edu.shnu.Dao.UserDAO"><property name="sessionFactory" ref="sessionFactory"/>   </bean>   <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" />   </bean>   <bean id="userDAOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"><property name="transactionManager" ref="transactionManager"/><property name="proxyInterfaces"><list><value>cn.edu.shnu.impl.IUserDAO</value></list></property><property name="target" ref="userDAO"/><property name="transactionAttributes"><props><prop key="insert">PROPAGATION_REQUIRED</prop></props></property>  </bean></beans>六、测试(SpringHibernateTest.java)package cn.edu.shnu.test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class SpringHibernateTest {public static void main(String[] args){ApplicationContext context = new ClassPathXmlApplicationContext("beans-config.xml");//建立DAO对象IUserDAO userDAO = (IUserDAO)context.getBean("userDAOProxy");User user = new User();user.setName("Nemo");user.setAge(new Integer(26));userDAO.insert(user);user = userDAO.find(new Integer(1));System.out.println("name: " + user.getName());       }}
