### 配置详情 ###

spring:
        datasource:
            type: com.alibaba.druid.pool.DruidDataSource
            druid:
                driver-class-name: com.mysql.cj.jdbc.Driver
                url: jdbc:mysql://localhost:3306/xxx?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai

### 解决方案 ###

只需要加上`&useSSL=false`

### 效果检测 ###

真的运行起来了！看来
