The server time zone value '' is unrecognized or represents more than one ti

使用hibernate保存数据到mysql时，报错"The server time zone value 'xxxxxxx' is unrecognized or represents more than one time zone.

<property name="hibernate.connection.url">jdbc:mysql:///test3?characterEncoding=utf8&amp;serverTimezone=GMT</property>

这是由于数据库和系统时区差异所造成的，解决方式是在数据库url地址后面加上serverTimezone=GMT
