Question

我正在使用spring-boot，Hibernate和MsSql。我将应用程序部署到服务器后，它正常工作了一段时间，之后它的数据库将断开连接并且无法重新连接。在日志中，它显示Hikari正在尝试连接但无法连接。

我正在从外部文件中读取数据库属性，并获得数据库连接。我是否需要在某个地方同时指定Hikari数据库属性，否则它将自动使用。

in application.properties specified
spring.datasource.hikari.connection-timeout = 20000 
spring.datasource.hikari.minimum-idle= 10 
spring.datasource.hikari.maximum-pool-size= 10
spring.datasource.hikari.idle-timeout=600000
spring.datasource.hikari.max-lifetime=1800000
spring.datasource.hikari.auto-commit =true

Spring Boot 2.0 Hikari自动连接不起作用
