我当前的配置如下：
使用spring-boot-starter-data-jpa版本2.2.4。发布 spring-cloud-dependencies Greenwhich.SR1
我已在application.properties中启用了以下属性
spring.datasource.hikari.maximum-pool-size = 30 spring.datasource.hikari.connection-timeout = 60000 spring.datasource.hikari.leak-detection-threshold = 20000
这是服务器启动时hikari的痕迹
