页面报错：

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

启动器报错：

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：

在配置文件 application.propertice 或 application.yml 中，添加时区 “serverTimezone=UTC”。

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/qfedu?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC&useSSL=true

然后清除缓存：
