REQUIRES_NEW：Spring 外部事務回滾，而不是在內部回滾時持久化

Question

我有一個 Spring 引導應用程序，其中我在 Controller 和服務之間有一個薄層，該服務僅用於 try-catch 並且如果拋出異常，則使用 JpaRepository 保留失敗的實體，以便后續檢查。 我設計了我的“攔截器”，如：

    @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;
       }
   }

我的服務方法如下：

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

我期望的是，如果服務中拋出異常，內部事務將被回滾，異常將彈出，外部事務將保留我的數據，但 hibernate 日志顯示由於某種原因外部事務也回滾並且失敗數據不會被持久化。 我還需要外層的另一個傳播級別嗎？

問題是 Spring 在運行時異常上默認回滾，所以我需要一個

@Transactional(noRollbackFor = Exception.class)

在我的攔截器上讓它按我預期的那樣運行。
