Hikari数据池在Spring启动应用程序中关闭

Question

我们在迁移时面临以下问题。

Spring Batch 4.0.x from 3.0.x.
1.5.x的Spring Boot 2.0.x.
Spring核心5.0.x来自4.3.x.

重新启动应用程序后，我可以在一分钟后看到它将日志作为SpringBootJPAHikariCP - Shutdown initiated...抛出。但是，当我们触发Job Hikari启动新连接并按预期工作时。但我不确定为什么第一个连接在一分钟后关闭。

我知道SpringBoot2.0使用Hikari作为数据库池，但不确定为什么我看到在理想时间一分钟后关闭信息日志。
