java - @Transactional 的默认传播行为

Question

我有以下代码:

@Component
public class A{ 

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

}

我没有为 @Transactional 注释指定任何传播行为。所以我想知道 Spring 中 @Transactional 的默认传播行为是什么？

Answer 1

REQUIRED是默认传播

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.
