需要新的:spring外部事务回滚,而不是在内部回滚时持久化

我有一个spring-boot应用程序,在控制器和服务之间有一个薄层,它的唯一目的是尝试捕获,如果抛出异常,用jparepository持久化失败的实体,以便后续检查。我的“拦截器”是这样设计的:

@Transactional
    public void upload(byte[] bytes) {
       try {
          service.upload(bytes);
       } catch (Exception e) {
           failRepo.save(new Failure(bytes, e)); // code trimmed for brevity 
           throw e;
       }
   }

我的服务方法是:

@Transactional(propagation = Propagation.REQUIRES_NEW, rollbackFor = Exception.class)
public void upload(byte[] bytes);

我所期望的是,在服务中抛出异常的情况下,内部事务将被回滚,异常将弹出,外部事务将持久化我的数据,但是hibernate日志显示,由于某种原因,外部事务也会回滚,失败数据不会持久化。我还需要在外层上的另一个传播级别吗?

问题是spring在运行时异常时默认回滚,所以我需要一个

@Transactional(noRollbackFor = Exception.class)

在我的拦截器上让它像我预期的那样运行。
