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：
