出现的错误：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 propert

在application.yml数据源配置中url后面加上如下修改：
url: jdbc:mysql://127.0.0.1:3306/seckill?serverTimezone=UTC
