IntelliJ IDEA中遇到服务器时区值‘�й���׼ʱ��‘ 无法识别或表示多个时区。_to use a more specifc time zone value if you want

显示代码错误如下： jdbc一直连接不成功

java.sql.SQLException: The server time zone value ‘�й���׼ʱ��’ 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. at

我试了有以下方法：

• 方法一：
  在pom.xml中加<scope>runtime</scope>，主要原因可能是版本太高导致的

• 方法二：
  不加版本号或者版本号为6以上，解决方式：在连接数据库的配置文件中加上以下，时区亚洲/上海 别的博主哪里看到的学习到的加时区的方法
  不过啦我也没有用到，应该对有些需要人用的到。
  
  mysql版本为8.0.17，是比较特殊的版本类型，所以我的mysql语句是这样的

• 方法三：
  更改一下mysql的时区即可
  
  查看时区配置：

show variables like '%time_zone%';
1

更改为当前时区：

set global time_zone='+8:00';
1

从这个博主哪里偷师过来的，我用第三种一下就成功啦啦！！！终于改出来bug了！撒花！！撒花！！
