spring，hibernate配置事务

1. 新建java project

2. 引入jar

3. src下新建package：com.web.model, com.web.dao, com.web.service, bean.xml

4. model下新建User.java

package com.web.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Entity
public class User {
	@Id
	@GeneratedValue
	private int id;

	@Column(length=32)
	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;
	}
}

dao下新建interface  IUserDao.java

package com.web.dao;

import com.web.model.User;

public interface IUserDao {
	public void save(User user);
}

dao下新建接口的实现类 UserDao.java

注意：

1. @Repository

2. @Resource 植入sessionfactory

package com.web.dao;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;
import org.springframework.web.bind.annotation.SessionAttributes;

import com.web.model.User;

@Repository
public class UserDao implements IUserDao {

	@Resource
	private SessionFactory sessionFactory;
	public SessionFactory getSessionFactory() {
		return sessionFactory;
	}
	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}
	public void save(User user) {
		Session session = sessionFactory.getCurrentSession();
		session.save(user);
	}

}

service下新建接口IUserService.java

package com.web.service;
import com.web.model.User;
public interface IUserService {
	public void save(User user);
}

service下新建接口实现类UserService.java

package com.web.service;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.web.dao.UserDao;
import com.web.model.User;

@Service
@Transactional
public class UserService implements IUserService {
	@Resource
	private UserDao userDao;

	public void save(User user) {
		userDao.save(user);
		int i=1/0;
		userDao.save(user);
	}

}

beans.xml

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

	<bean id="dataSource"	class="org.apache.commons.dbcp.BasicDataSource" 	destroy-method="close">

	</bean>

	<bean id="txManager"

	</bean>

	<tx:annotation-driven transaction-manager="txManager"/>
	<!-- 	<aop:aspectj-autoproxy proxy-target-class="true"/>  -->
</beans>

5. 新建source folder：test  ，新建package：com.web.service,用于测试service

package com.web.service;

import static org.junit.Assert.*;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.web.model.User;

public class UserServiceTest {
	@Resource
	private SessionFactory sessionFactory;

	private ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");

	@Test
	public void testSessionFactory() {
		sessionFactory=(SessionFactory)ac.getBean("sessionFactory");
		System.out.println(sessionFactory);
	}

	@Test
	public void testUserService(){
		IUserService iuserService=(IUserService)ac.getBean("userService");
		System.out.println(iuserService);
		iuserService.save(new User());
	}
}
