@Transactional 的默认传播行为

Question

I have the following code:

@Component
public class A{ 

 @Transactional
 public void classa(){
     //logic
 }

}

I don't specify any propagation behaviour for @Transactional annotation. So I want to know what is the default propagation beahaviour for @Transactional in spring?

Answer 1

REQUIRED is the default propagation

REQUIRED public static final Propagation REQUIRED Support a current transaction, create a new one if none exists. Analogous to EJB transaction attribute of the same name. This is the default setting of a transaction annotation .
