HikariCP 最初关闭

Question

首先，我不是Java开发人员。 但是，我有一个用 Java 开发的服务，直到今天都按预期工作。 我们的数据库服务器出现磁盘错误，因此我们返回 VMVare 备份。
我在不同机器上的服务没有按预期工作（或看起来工作但不工作）。
一年多以前开发的最后一个 Java 代码。 所以任何配置都改变了。 我得到那个日志，我被挤压了。

Answer 1

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

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，您还会在连接池上收到关闭命令。 但这不仅仅是连接池。 它就是一切。

从我在启动 spring 服务关闭之前的日志中可以看到，您的休眠会话已关闭。 这在日志的前一行中可见。

您需要弄清楚为什么您的 spring 应用程序关闭以及您的休眠会话为什么关闭，Hikari 关闭只是一个副作用。
