【问题描述】：
我有一个 Spring Boot 应用程序，其中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，则使用 JpaRepository 保存失败的实体，以供后续检查。 我设计了我的“拦截器”：
@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;
}
}
我的服务方法如下：
@Transactional(propagation = Propagation.REQUIRES_NEW, rollbackFor = Exception.class)
public void upload(byte[] bytes);
我期望的是，如果服务中抛出异常，内部事务将被回滚，异常会弹出并且外部事务将保留我的数据，但是休眠日志显示由于某种原因外部事务也回滚并且失败数据不会被持久化。 我还需要外层的另一个传播级别吗？

【问题讨论】：
-
请提供日志。另外，能否在调试模式下检查代码流，看看是否捕获了异常？
-
@aksappy 是的，在 catch 子句中成功捕获了异常，Failure 对象创建得很好，异常被重新抛出。唯一的问题是失败没有持续存在。更新了问题以包含相关日志。
-
请提供您的源代码。我看不到您在外部事务中插入内容的位置
-
FailRepo 是一个 JpaRepository，我在其上调用默认的 save() 方法。编辑了问题。
