SpringBoot项目连接mysql数据库时产生

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.

这是由于数据库和系统时区差异所造成的，在jdbc连接的url后面加上serverTimezone=GMT

在jdbc连接的url后面加上?serverTimezone=GMT

添加前

jdbc:mysql://localhost:3306/springboot

添加后

jdbc:mysql://localhost:3306/springboot?serverTimezone=GMT
