Spring Application Properties

refer to : https://docs.spring.io/spring-boot/docs/current/reference/html/application-properties.html#application-properties.data.spring.datasource.hikari

除了通过上面的网址，能够查询到application.properties中，可以配置哪些配置项，还可以通过查看spring-configuration-metadata.json文件，进行查询。

路径如下：
spring-boot-autoconfigure-2.7.12.jar!\META-INF\spring-configuration-metadata.json
