idea连接mysql数据库报java.lang.RuntimeException: com.mysql.cj.exceptions.InvalidConnectionAttributeExcepti

出错场景：

使用idea连接mysql（5.2版本）报错：

java.lang.RuntimeException: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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.

大概原因：

 JDBC驱动程序的5.2版本与UTC时区配合使用，必须在连接字符串中明确指定serverTimezone。

解决方法：

jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
