问题：
Spring异步作业中出现异常-InvalidDataAccessApiUsageException:没有正在进行的事务
元嘉木
场景是，我有一个带有spring批处理作业的spring启动应用程序。我正在尝试使用@EnableAsync和ThreadPoolTaskExecutor使批处理作业异步，然后将此taskExecutor分配给JobLauncher。更改后，作业会异步运行，但我在持久化或更新数据库方面遇到了问题：

我已经在其他上下文中遇到了这种问题，并且只有一种有效的方法可以找到来源：将断点放在org.hibernate.internal.SessionImpl.checkTransactionNeed和org.springframework.transaction.interceptor.TransactionAbulSupport.invokeAnd inTransaction中试着理解为什么后面创建的事务（应该是）第一个不能识别。

JobExecution#beforeJob不在Spring Batch管理的事务范围内执行。您可能需要将@Transactional添加到WriteToFileJobExecutionListener#beforeJob方法中。

用@Transactional（propagation=propagation.REQUIRES_NEW）注释负责数据库访问逻辑的作业方法。

我有一个JPA web应用程序，其中包含一些针对JPA存储库的集成测试。目前还没有针对Neo4J存储库的集成测试。 现在，我已经向这个现有的JPA web应用程序添加了一些Neo4J功能。 我现在使用Neo4J存储库和JPA存储库。我的实体和存储库的名称不同，并且位于不同的包中。 我的所有测试都扩展了以下类： 当应用程序配置没有任何配置时，测试可以正常运行 但在添加Neo4J配置时出现异常错误：

我已经阅读了Spring@Transactional-Isolation,propagation中的指令 但是我不明白我解释的这个特性是如何产生的：我有一个异步方法，像这样 此方法（setFlag）在调用异步方法之前通过1L调用一次 并且在异步方法中的所有操作结束时传递零 但是，如果异步方法因某些问题而失败，则catch分支中的调用将失败，因为 且标志保持为1。 所以，我希望我是清楚的，但是...

我正在Spring3和Hibernate3中进行产品构建，我已经更新了这个Hibernate5和Spring5。现在我可以部署应用程序了，但是当我尝试与数据库连接时，会得到“javax.persistence.TransactionRequiredException：no transaction is in progress”
