解决：Hikari - Exception during pool initialization.

记录一下解决方法

首先确保pom.xml文件中有Haikari的坐标

        
            mysql
            mysql-connector-java
            8.0.16
        
  
        
           com.zaxxer
           HikariCP
        

然后启动项目，正常。

执行数据库操作：Hikari - Exception during pool initialization.

哎，肯定是哪配置出问题了，百度了一下，发现是mysql连接的问题，URL连接后面追加   useSSL=false

贴出我的配置

server:
  port: 8080
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/test?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=false
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.zaxxer.hikari.HikariDataSource
    hikari:
      minimum-idle: 10
      maximum-pool-size: 50
      auto-commit: true
      idle-timeout: 30000
      pool-name: MyHikari

我的问题解决！ 成功取出数据
