【踩坑】环境问题

SpringBoot+JDK 8+ MySQL 8 +druid

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

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

注意mysql8，上面这两个serverTimezone=UTC 和 com.mysql.cj.jdbc.Driver 对比之前是不同的~
