在我使用MySQL8.0搭建javaweb项目时遇到了 idea给我报MySQL了时区的问题
Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value '???ú±ê×??±??' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

然后我们有几种解决的方法：
方法一：
set time_zone = "+8:00";
set global time_zone = "+8:00";
这两个都可以第一个设置了不行的话再设置第二句代码
方法二：
加上这句?serverTimezone=GMT修改时区
然后再次执行项目启动
部署完毕：么么么么么哒
