[英]spring jpa @transaction doesn't rollback
My project encountered the problem that Spring JPA transactions would not roll back. 我的项目遇到了Spring JPA事务不会回滚的问题。 The project framework is spring MVC + Spring + spring data JPA + oracle.
该项目框架是spring MVC + spring + spring data JPA + oracle。 I searched a lot of information on the Internet, but still could not solve my problem.
我在Internet上搜索了很多信息,但仍然无法解决我的问题。
I've tried many ways, such as setting the method to public or adding rollbackFor = Exception.class
in @Transactional
, but it still can't be solved. 我尝试了很多方法,例如将方法设置为public或在
@Transactional
添加rollbackFor = Exception.class
,但仍然无法解决。
Here's my code 这是我的代码
Controller 调节器
@RequestMapping(value = {"addUser"}, method = RequestMethod.GET)
@ResponseBody
public Boolean insertUser() throws Exception{
User user = new User();
user.setId(10);
userServiceI.addUser(user);
return true;
}
Service 服务
Service Interface 服务介面
public interface UserServiceI {
void addUser(User user);
}
Service Implementation class 服务实施类
@Service
public class UserService implements UserServiceI {
@Autowired
public UserDao userDao;
@Autowired
PersonService personService;
@Override
@Transactional(propagation= Propagation.REQUIRED,rollbackFor=Exception.class)
public void addUser(User user){
User user1 = userDao.saveAndFlush(user);
System.out.println(1/0);
}
}
Dao 道
public interface UserDao extends JpaRepository<User,Integer> {
}
My @Transactional
method loads my implementation class Service, which writes an error-prone 1/0. 我的
@Transactional
方法加载了我的实现类Service,该类写入容易出错的1/0。 I expect the transaction to roll back after the error, but it doesn't. 我希望错误发生后事务会回滚,但事实并非如此。
Adding @Repository
in your UserDao can be a possible fix of that error. 添加
@Repository
在你的UserDAO可以是错误的可能修复。
Not sure but it can work. 不确定,但是它可以工作。
Oh, I solved it because I omitted in applicationContext.xml. 哦,我解决了它,因为我在applicationContext.xml中省略了。 I only wrote in spring-mvc.xml.
我只写了spring-mvc.xml。 I always thought that I only need to write this in one of them.
我一直以为我只需要用其中之一写这个。 Until I saw this article labreeze.iteye.com/blog/2359957.
直到我看到这篇文章labreeze.iteye.com/blog/2359957。 I am too happy and negligent.
我太高兴了,疏忽了。
if you are in a springboot project context you have to add @EnableTransactionManagement in your configuration class 如果您在springboot项目上下文中,则必须在配置类中添加@EnableTransactionManagement
if it's a non springboot project, add in your xml configuration file (where is declared your component-scan) the annotation-driven tag 如果它是非springboot项目,则在xml配置文件(声明为组件扫描)中添加注释驱动的标签
