Spring Boot 启用数据源连接日志，例如连接 URL、用户名、密码等

Question

我正在使用 jenkin 和 kubernetes 将 boot-app 的 jar docker 映像部署到嵌入式 tomcat 服务器。它抛出一个异常 -

com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException：无法创建与数据库服务器的连接。尝试重新连接 3 次。放弃

应用程序已成功部署在我的区域设置上，对于我的本地设置，以下是相关属性-

spring.datasource.url=jdbc:mysql://localhost:3306/mydb?autoReconnect=true&useUnicode=true&CharSet=UTF-8&characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=password

我只想在部署 docker 映像时检查它尝试连接的 url、服务器上的用户和密码。Spring Boot 有什么方法可以在部署应用程序时启用此类日志吗？

我尝试了下面的许多可用选项 -
