　　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)
}
}
