spring 事务 PROPAGATION_NESTED纠错

[1autodidact]

ROPAGATION_NESTED：如果当前存在事务，就在嵌套事务内执行；如果当前没有事务，就执行与PROPAGATION_REQUIRED类似的操作，子事务回滚外部主事务也会受到影响进行回滚

@Service
public class UserInvokeService {
    @Autowired
    private UserService userService;
    @Resource
    private UserMapper userMapper;

    @Transactional
    public void invokeUserService() {
        User user = new User();
        user.setName("zxx");
        user.setAge(333333);
        userMapper.insert(user);
        userService.insertData();

    }
}


@Service
public class UserService {

    @Resource
    private UserMapper userMapper;


    @Transactional(propagation = Propagation.NESTED)
    public void insertData() {
        User user = new User();
        user.setName("inserByNested");
        user.setAge(2222);
        userMapper.insert(user);
        int a = 1 / 0;
    }

}


@SpringBootTest
public class TransactionalTest {
    @Autowired
    UserService userService;
    @Autowired
    UserInvokeService userInvokeService;
    @Test
    public void testTransaction() {
        userInvokeService.invokeUserService();
    }
}
