      配置文件内容:

#数据库连接池设置
dataSource.driver=com.mysql.jdbc.Driver
dataSource.url=jdbc:mysql://localhost:3306/dwz
dataSource.username=root
dataSource.password=root

dataSource2.driver=oracle.jdbc.driver.OracleDriver
dataSource2.url=jdbc:oracle:thin:@192.168.10.43:1521:test
dataSource2.username=test
dataSource2.password=test

 

 

      Service类代码:

package org.zhuc.mybatis.service;

import org.springframework.transaction.annotation.Transactional;

/**
 * 基础mysql Service抽象类
 * 使用isap数据源及回滚
 * @author zhuc
 * @create 2013-3-11 下午4:27:33
 */
@Transactional(value = "isap", rollbackFor = Exception.class)
public abstract class BaseMySqlService {

}

 

package org.zhuc.mybatis.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.zhuc.mybatis.domain.User;
import org.zhuc.mybatis.mapper.UserMapper;

/**
 * @author zhuc
 * @create 2013-3-11 下午1:19:03
 */
@Service("userService")
//@Transactional(value = "isap", rollbackFor = Exception.class)
public class UserService extends BaseMySqlService {

	@Autowired
	private UserMapper userMapper;

	/**
	 * @param id
	 * @return
	 */
	public User get(Integer id) {
		return userMapper.get(id);
	}

	/**
	 * @param id
	 * @return
	 */
	public User get2(Integer id) {
		return userMapper.get2(id);
	}

	/**
	 * @return
	 */
	public List<User> findAll() {
		return userMapper.findAll();
	}

	/**
	 * @param user
	 * @throws Exception 
	 */
	public void insert(User user) throws Exception {
		userMapper.insert(user);
		throw new Exception("testException");
	}
}

 

package org.zhuc.mybatis.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import org.zhuc.mybatis.domain2.Flow;
import org.zhuc.mybatis.mapper2.FlowMapper;

/**
 * @author zhuc
 * @create 2013-3-11 下午1:19:03
 */
@Service("flowService")
@Transactional(value = "insurance", rollbackFor = Exception.class)
public class FlowService {

	@Autowired
	private FlowMapper flowMapper;

	/**
	 * @param id
	 * @return
	 */
	public Flow get(String id) {
		return flowMapper.get(id);
	}

}

 

 

      客户端测试类如下:

package spring;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.zhuc.mybatis.service.FlowService;
import org.zhuc.mybatis.service.UserService;

/**
 * @author zhuc
 * @create 2013-3-11 下午1:47:03
 */
public class MultiTest {

	/**
	 * @param args
	 * @throws Exception 
	 */
	public static void main(String[] args) throws Exception {
		ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
		UserService userService = (UserService) ac.getBean("userService");
		System.out.println(userService.get(1));
		System.out.println(userService.get2(1));

		FlowService flowService = (FlowService) ac.getBean("flowService");
		System.out.println(flowService.get("94003d29-a7b0-42f0-839c-fa609b209ff1"));

		//		User user = new User();
		//		user.setId(100);
		//		user.setUserName("admin100");
		//		user.setPassword("password100");
		//		user.setTrueName("小李4");
		//		user.setCreateTime(new Date());
		//
		//		userService.insert(user);	//受事务管理,抛出Exception时将回滚  (rollbackFor)
	}

}

 

 

      输出结果:

应该只适用于不同数据源的表结构也不同的情况,如果是多个数据源表结构相同就不行了

您好,我也用到同样的功能了,但是我的

你好,我也想请教一下,如果每一个service是独立的事务,那要想在一个service里面完成对2个数据库的操作该如何做
2 楼 zhuchengzzcc 2013-03-22  
asgab 写道
同一个service修改两个数据库的数据,事务怎么控制?


不是,每一个service是独立的事务,请注意看
@Transactional(value = "insurance", rollbackFor = Exception.class)
@Transactional(value = "isap", rollbackFor = Exception.class)

注解式的事务声明,
对应的insurance代表Oracle,  isap代表Mysql
