JDBC连接M有SQL数据库报错The server time zone value '???ú±ê×??±??' is unrecognized or represents........

利用JDBC连接数据时，会报错误具：java.sql.SQLException: 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.具体错误如图所示：

解决办法：mysql返回的时间总有问题，一般总是早8小时。String url = "jdbc:mysql://localhost:3307/mysql_xy?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false";

即可。
