SpringApplication.exit() 返回 java.lang.InterruptedException: null

如何解决SpringApplication.exit() 返回 java.lang.InterruptedException: null

最近我把spring boot版本从2.3.4升级到了2.4.2。我有以下代码可以正常关闭应用程序。

taskScheduler.schedule(() -> SpringApplication.exit(applicationContext,() -> 0),Instant.Now().plus(30,ChronoUnit.SECONDS));

这段代码在升级前运行良好。现在它给出了以下异常并且应用程序继续运行（不终止）。

知道如何解决这个问题吗？

更新：

根据@vvs 的回答，我更改了代码以首先关闭 Hikari 数据源。现在 InterruptedException 不存在。令人惊讶的是，该应用程序仍在运行。我可以看到下面的日志经常记录。意思是，这些线程没有终止。

解决方法

认为这是您的应用程序终止逻辑中的一个问题。 请在 HikariCP 上查看此问题 https://github.com/brettwooldridge/HikariCP/issues/1295

决议说

看起来像是在 SpringApplication.exit() 修复问题之前调用了 hikariDataSource.close()
