报错The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone.

原因是，你的application.properties里面的url末尾少写了

serverTimezone=GMT%2B8

比如我的Url原本是这样的： 

spring.datasource.url=jdbc:mysql://localhost:3306/hero?useUnicode=true&characterEncoding=utf8&useSSL=false

再末尾加上

&serverTimezone=GMT%2B8

变成

spring.datasource.url=jdbc:mysql://localhost:3306/hero?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8
