Spring异步作业中的异常 - InvalidDataAccessApiUsageException：没有正在进行的事务

标签： hibernate spring-boot jpa asynchronous spring-batch

场景是，我有一个弹簧批处理作业的弹簧启动应用程序。我尝试使用@EnableAsync和ThreadPoolTaskExecutor使批处理作业异步，然后将此taskExecutor分配给JobLauncher。在此更改之后，作业以异步方式运行，但我遇到了持久化或更新数据库的问题：

感谢您的帮助！

3 个答案:

答案 0 :(得分：0)

用@Transactional(propagation = Propagation.REQUIRES_NEW)注释处理数据库访问逻辑的作业方法。

答案 1 :(得分：0)

JobExecution#beforeJob未在Spring Batch管理的事务范围内执行。您可能希望将@Transactional添加到WriteToFileJobExecutionListener#beforeJob方法。

答案 2 :(得分：0)

我已经在其他环境中遇到过这种问题，只有一种有效的方法可以找到来源： 在org.hibernate.internal.SessionImpl.checkTransactionNeeded中放置断点 在org.springframework.transaction.interceptor.TransactionAspectSupport.invokeWithinTransaction中 然后尝试理解为什么后来创建的事务（假设确实如此）不会被第一个人识别。
