Java Spring boot 2属性Spring.jpa.open in view=true导致非法状态异常：EntityManager在关机时关闭

我用h2数据库创建了一个示例SpringBoot2.1.5.Release项目

当我试图关闭应用程序时，它抛出了

非法状态异常：EnityManager已关闭

我将

@PersistantContext

与

@Transactional

一起使用

我的应用程序不支持任何异步任务。我甚至为

ThreadPoolTaskExecutor

尝试了

WaitForTasksToCompleteOnShutdown=true

，但在关机时仍然显示相同的异常

后来我找到了这个jpa属性和post，然后我尝试了

spring.jpa.open in view=false

并解决了

IllegalStateException

。 在这里我了解到，建议将

spring.jpa.openin view

设置为false

但是我仍然不理解spring引导的默认设置

spring.jpa.open in view=true

，为什么我的应用程序会抛出异常

如何使用

spring.jpa.open in view=true

处理此场景，而它没有抛出

IllegalStateException:EntityManager已关闭

你可以在github上引用我上传的代码

应用程序关闭时的Stacktrace：

如有可能，请考虑提供。这样，志愿者就更有可能帮助你。你能把stacktrace包括进来吗？你是怎么关机的？看起来在关机期间仍有一个请求正在处理。它失败了，因为关机已经开始关闭应用程序上下文并销毁bean。@M.Deinum我试图通过关闭进程来关机。我也用执行器试过。执行器在

/shutdown

？无论是否有请求传入，是否启用了监视功能？或者尤里卡或者？。所有这些都使用Web请求周期性地对应用程序进行轮询，即使应用程序正在关闭（外部进程不知道）。请考虑提供一个可能的情况。这样，志愿者就更有可能帮助你。你能把stacktrace包括进来吗？你是怎么关机的？看起来在关机期间仍有一个请求正在处理。它失败了，因为关机已经开始关闭应用程序上下文并销毁bean。@M.Deinum我试图通过关闭进程来关机。我也用执行器试过。执行器在
