MySQL url问题

create connection SQLException, url: jdbc:mysql://localhost:3306/ems_thymeleaf?serverTimezone=CTT&amp;useUnicode=true&characterEncoding=utf-8&useSSL=false, errorCode 0, state 08001

里面的CJ是看网上评论添加上去的

 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
    spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

报错代码
