hibernate与spring整合实现transaction

实现transaction时出现了大大小小的问题，这里会一一详解。

先贴出applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

           http://www.springframework.org/schema/aop

           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd

           http://www.springframework.org/schema/tx

         http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

    <context:annotation-config />

    <context:component-scan base-package="com.bjsxt"/>

    <!-- <aop:aspectj-autoproxy></aop:aspectj-autoproxy> -->

    <!-- <bean id="logInterceptor" class="com.bjsxt.aop.LogInterceptor"></bean>

    <aop:config>

        <aop:aspect id="logAspect" ref="logInterceptor">

        </aop:aspect>

    </aop:config> -->

    <bean

        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

        <property name="locations">

            <value>classpath:jdbc.properties</value>

        </property>

    </bean>

    <bean id="dataSource" destroy-method="close"

        class="org.apache.commons.dbcp.BasicDataSource">

        <property name="driverClassName"

            value="${jdbc.driverClassName}" />

        <property name="password" value="${jdbc.password}" />

    </bean>

    <bean id="sessionFactory"

        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

        <property name="dataSource" ref="dataSource" />

        <property name="annotatedClasses">

            <list>

                <value>com.bjsxt.model.User</value>

                 <value>com.bjsxt.model.Logs</value>

            </list>

        </property>

        <property name="hibernateProperties">

            <props>

                <prop key="hibernate.dialect">

                    org.hibernate.dialect.MySQLDialect

                </prop>

                <prop key="hibernate.show_sql">true</prop>

            </props>

        </property>

    </bean>

     <!-- enable the configuration of transactional behavior based on annotations -->

     <tx:annotation-driven transaction-manager="txManager"/>

   <bean id="txManager"

            class="org.springframework.orm.hibernate4.HibernateTransactionManager">

    <property name="sessionFactory" ref="sessionFactory"/>

  </bean>

</beans>

这里注意，一定要加上

xmlns:tx="http://www.springframework.org/schema/tx"

  http://www.springframework.org/schema/tx

         http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

否则会报找不到annotation-driven的错误

贴出service

package com.bjsxt.service;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.beans.factory.annotation.Qualifier;

import org.springframework.stereotype.Component;

import org.springframework.transaction.annotation.Transactional;

import com.bjsxt.dao.LogsDAO;

import com.bjsxt.dao.UserDAO;

import com.bjsxt.model.Logs;

import com.bjsxt.model.User;

@Component("userService")

public class UserService {

    private UserDAO userDAO;

    private LogsDAO logsDAO;

    public LogsDAO getLogsDAO() {

        return logsDAO;

    }

    @Resource(name="thelogs")

    public void setLogsDAO(LogsDAO logsDAO) {

        this.logsDAO = logsDAO;

    }

    public void init() {

        System.out.println("init");

    }

    @Transactional

    public void add(User user) {

        userDAO.save(user);

        Logs thelogs=new Logs();

        thelogs.setMsg("add a user");

        logsDAO.sava(thelogs);

    }

    public UserDAO getUserDAO() {

        return userDAO;

    }

    @Resource(name="u")

    public void setUserDAO( UserDAO userDAO) {

        this.userDAO = userDAO;

    }

    public void destroy() {

        System.out.println("destroy");

    }

}

贴出LogsDAOImpl和UserDAOImpl其中的LogsDAOImpl

package com.bjsxt.dao.impl;

import javax.annotation.Resource;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.springframework.stereotype.Component;

import com.bjsxt.dao.LogsDAO;

import com.bjsxt.model.Logs;

@Component("thelogs")

public class LogsDAOImpl implements LogsDAO {

    private SessionFactory sessionFactory;

    public SessionFactory getSessionFactory() {

        return sessionFactory;

    }

    @Resource

    public void setSessionFactory(SessionFactory sessionFactory) {

        this.sessionFactory = sessionFactory;

    }

    @Override

    public void sava(Logs logs) {

        // TODO Auto-generated method stub

        Session s=sessionFactory.getCurrentSession();

        s.save(logs);

    }

}

测试类

ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");

        UserService service = (UserService)ctx.getBean("userService");

        System.out.println(service.getClass());

        service.add(new User("22","22"));

        ctx.destroy();

执行结果

class com.bjsxt.service.UserService$$EnhancerByCGLIB$$6dcce04e

session factory class:class org.hibernate.internal.SessionFactoryImpl

Hibernate: insert into User (password, username) values (?, ?)

user saved!

Hibernate: insert into Logs (msg) values (?)

注意的是本次使用的是spring3.1.1和hibernate4.0

如果使用的是hibernate4.3以上的话会报org.hibernate.engine.spi.sessionFactoryImplementor.getConnectinoProvider()这个类找不到。是版本的问题
