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) } }
