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.
### The error may exist in mappers/UserMapper.xml
### The error may involve com.jql.mybatis.mapper.UserMapper.getUser
### The error occurred while executing a query

解决办法：
在链接url后面添加?serverTimezone=UTC

注意：
