java - 如何处理 "Transaction was marked for rollback only; cannot commit; "问题？

Question

public class A{
    @Async
    public void methodA(){
        someService.methodB();
    }
}

public class someServiceImpl implements someService{

    @Transactional(noRollbackFor = Exception.class)
    public void methodB(){

        try{

        //to do
        }catch(Exception e){
            log.error(e.getMessage());
        }
    }
}

例如，我使用'@Transactional'来标记我的方法希望在发生错误时提交事务。但是问题仍然发生如下:

我该如何解决这个问题？谢谢。

我猜您的服务调用了用 @Transactional 注释的其他组件，对吗？如果调用此其他组件时发生异常并在 SomeServiceImpl 中捕获，那么当事务系统尝试在 methodB 中提交事务时，您将遇到您所描述的异常。任何传递 @Transactional 边界的异常都会将周围事务标记为仅回滚，除非您明确告诉系统否则。

如果您希望周围事务(即为 methodB 创建的事务)“幸存”此异常，则需要更改目标组件(即抛出异常的组件)带有noRollbackFor。
