Question

似乎Spring Batch在与它调用的ejbs相同的事务中运行。因此，当我们在ejbs中获得回滚时，Spring Batch无法在数据库中更新其状态。

我们得到的例外是：

如果步骤失败，我们如何确保Spring Batch能够更新其状态？这是Spring Batch中的错误，还是我们做错了什么？

Answer 1

批次是否也在ejb内运行？ ejbs的交易设置是什么？ BMT还是CMT？你在批处理中从哪里调用EJB？读者，处理器，作家？监听？您是否尝试通过代码中的常规catch（Exception e）处理导致ejb回滚的异常，跳过或重试？

Answer 2

似乎问题出现在我们的joblaunchers配置中。

我们有一些进程启动其他进程，当他们使用相同的taskExecutor实例时，回滚会回滚任务本身。

不是100％确定这是否修正了错误，但它现在正在运作： - ）

由于RollbackException，Spring Batch无法更新其状态
