如何解决hikari连接使应用程序无响应
在企业网络上，我正在使用springboot应用程序，该应用程序默认具有Hikari连接池机制。启动应用程序时已建立数据库连接，以下是Hikari Pool配置：-

我遇到一个问题，即在启动了一天的负载后，Spring Boot服务突然运行了一天，由于我假设驱动程序与驱动程序试图访问的数据源之间的通信链接，应用程序突然变得无响应。应用程序执行某些操作时连接失败，导致以下日志和应用程序未执行任何其他操作。
有时错误是：-
WARN 98332 --- [ scheduling-1] com.zaxxer.hikari.pool.ProxyConnection : HikariPool-1 - Connection ConnectionID:1 ClientConnectionId: 91a118c1-e9c5-4bda-beae-bb8fba1ca9bf marked as broken because of sqlSTATE(08S01),ErrorCode(0)

有时在网络薄弱的时候，间歇性地看到该应用程序无响应，只有Hikari管家日志可以显示如下，而没有其他内容。

即使添加了新的连接，我们也只能看到active = 0。 我们如何使我们的Hikari连接正常关闭，并用另一个丢失数据的方式替换它。在此方面的任何帮助，我将不胜感激。谢谢！
