java.sql.SQLException: The server time zone value '�й���׼ʱ��' is unrecognized or represents more than one time zone

报错信息：
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.

解决方法（修改application.yml配置文件）：

在url后面添加?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC

spring:

  datasource:
#   数据源基本配置
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/nnluck?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
