报错: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.
原因及解决方案:
可能是使用了当前最新的mysql-connector-java MySQL驱动包，新的驱动包中com.mysql.jdbc.Driver类已经过时，新的是:com.mysql.cj.jdbc.Driver通过SPI自动注册，不再需要手动加载驱动类,把版本换低一点就好了
