使用原来基于MySQL 5.1的JDBC代码运行时，报错：

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JDBC所在的系统时差引起，在jdbc连接的url后面加上参数serverTimezone=GMT可解决问题，如果使用gmt+8时区，需要对gmt+8转码，写成GMT%2B8。

最后将url改成类似于下面得样子：

jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8//test后的即是要添加的
