springboot 事务自调用失效

---

springboot 事务自调用失效

 

产生原因：spring事务底层使用动态代理，若同一个类中的方法吊用另一个方法，则不存在对象之间的代理关系，被调用方法的事务失效

解决方法：在另一个类中调用需要调用的方法

示  例

 

*****************

service 层

 

public interface CustomPersonService {

    void update(Person person);

    void insert(Person person);

    void insertList(List personList);
}

*********************

serviceImpl 层

 

@Service
public class CustomPersonServiceImpl implements CustomPersonService {

    @Autowired
    private PersonMapper personMapper;

    @Override
    @Transactional(propagation = Propagation.REQUIRED)
    public void update(Person person) {
        personMapper.updateById(person);
    }

    @Override
    @Transactional(propagation = Propagation.NESTED)
    public void insert(Person person) {
        personMapper.insert(person);
    }

    @Override
    @Transactional(propagation = Propagation.REQUIRES_NEW)
    public void insertList(List personList) {
        for(Person person:personList){
            insert(person);
        }
    }
}

 

*******************

controller 层

 

@RestController
@RequestMapping("/person")
public class PersonController {

    @Autowired
    private PersonService personService;

    @Autowired
    private CustomPersonService customPersonService;

    @RequestMapping("/save")
    public String save(){
        List list=new ArrayList<>();
        for(int i=0;i<10;i++){
            Person person=new Person();
            person.setName("瓜田李下"+i);
            person.setAge(i);

            list.add(person);
        }

        customPersonService.insertList(list);

        return "success";
    }
}

可以看出，被调用方法的事务没有创建
