在Spring中是否可以从非事务方法中调用事务方法？

Question

Suppose I have a Repository class.

@Repository
class MyRepository {

    @Transactional
    void method1 () {
        // some logic here
    }

    void method2 () {
        // some logic here
        method1();
        // some logic here
    }
}

Is it possible to do that in String? And how this works?

Answer 1

This does not work, since this a self call . See
Spring @Transaction method call by the method within the same class, does not work?

Depending on your application and its responsibilities, you could create another bean for method2() . Apart from that, DAO methods should usually not be annotated @Transactional . See
Where does the @Transactional annotation belong?

Answer 2

This will not work because the method will go out of the scope of @Transaction when you will call the method2 . But you can apply a hack and call method2 using this from method1 in the following way.

this.method2();

Answer 3

You cannot do that because Spring wraps methods that will be called from another class (service). If you call annotated methods from withing the same class , Spring will do nothing as it cannot wrap them.

Answer 4

You should use self injection to call a Transactional method from a non Transactional one as in Spring you can't simply call @Transactional method from the same instance because of AOP-proxy thing

@Repository
class MyRepository {

    @Autowired
    MyRepository selfTxMyRepository;

    @Transactional
    void method1 () {
        // some logic here
    }

    void method2 () {
        // some logic here
        selfTxMyRepository.method1();
        // some logic here
    }
}
