*出現問題 logback
springcloud整合logback打印sql語句

*2.boot就會尋找是否有HikariCP可用

*2.1數據庫連接池 更替 HikariCP

*2.2 Loading class `com.mysql.jdbc.Driver’. This is deprecated.

    jdbc.driver=com.mysql.jdbc.Driver
    替換爲 ->
    jdbc.driver=com.mysql.cj.jdbc.Driver 
    # 具體更換
    spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver 
    spring.datasource.type=com.zaxxer.hikari.hikaridatasource
    
    
    # jdbc_config   datasource

    spring.datasource.username=M3LpmU1c
    spring.datasource.password=root
    # Hikari will use the above plus the following to setup connection pooling
    spring.datasource.type=com.zaxxer.hikari.HikariDataSource
    spring.datasource.hikari.minimum-idle=5

    # 坑 在類路徑上找到的Spring MVC，此時它與Spring Cloud網關不兼容。請刪除spring-boot-start-web依賴項。因爲spring cloud gateway是基於webflux的，如果非要web支持的話需要導入spring-boot-starter-webflux而不是spring-boot-start-web。
    
    將pom.xml中關於spring-boot-start-web模塊的jar依賴去掉。
