HikariCP初始关闭

Question

首先，我不是Java开发人员。但是，我有一个用Java开发的服务，一直到今天都能正常工作。我们的数据库服务器得到一个磁盘错误，所以我们返回VMVare备份。

我的服务在不同的机器上，没有像预期的那样工作(或者看起来工作但不工作)。

上一个Java代码是在一年多前开发的。因此，任何配置都已更改。我拿到了那根木头，我被挤压了。

Java版本: 1.8.0_151

Answer 1

这里没有错误，至少在Hikari的意义上没有错误。日志所说的是您的基于spring的应用程序正在关闭，这在这里是可见的：

DEBUG 28/05/2019 12:28:58 [main] [] [] [] HHH000031: Closing

DEBUG 28/05/2019 12:28:58 [main] [] [] [] Implicitly destroying Boot-strap registry on de-registration of all child ServiceRegistries

Spring正在关闭其应用程序上下文中的所有bean。作为一个副作用，你还会在你的连接池上得到一个shutdown命令。但这不仅仅是连接池。这就是一切。

从我在关闭spring服务之前的日志中可以看到，您的hibernate会话已经关闭。这在您的日志中的前一行中可见。

你需要弄清楚为什么你的spring应用程序要关闭，为什么你的hibernate会话被关闭，Hikari关闭只是一个副作用。
