註解方式

//註解主要是@Transactional("")
@Service("userService")
@Transactional("propagation=Propagation.REQUIRES_NEW")
public class UserServiceImpl implements UserService {

	@Autowired
	@Qualifier("userMapper")
	private UserMapper userMapper;
	public UserMapper getUserMapper() {
		return userMapper;
	}
	public void setUserMapper(UserMapper userMapper) {
		this.userMapper = userMapper;
	}
	@Override
	public List<User> findUsers(User user) {
		return userMapper.getUserList(user);
	}
	@Override
	public int addNewUser(User user){
		return userMapper.add(user);
	}
	@Override
	public int addNewUserList(List<User> users) {
		int count = 0;
		for(User user:users){
			count += addNewUser(user);
//			throw new RuntimeException("ERROR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
		}
		return count;
	}
