启动项目时报错：java.sql.SQLException: The server time zone value ‘�й���ʱ��‘ is unrecognized or represents
报错信息：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.
解决方案：
1、尝试了网上说的修改本地mysql的市区，没用
2、尝试在mysql连接的url地址后面加上 &serverTimezone=Asia/Shanghai，没用
后来发现pom文件中mysql-connector-java 对应的版本和我电脑本地安装的mysql版本不一致，将版本修改成我本地安装的版本后重启服务，就可以了
