com.mysql.cj.jdbc.Driver和serverTimezone=GMT%2B8 数据库的配置

com.mysql.jdbc.Driver 和 com.mysql.cj.jdbc.Driver的区别与设置

spring:
  messages:
    encoding: UTF-8
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://172.16.17.103:3306/declaration?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8&useSSL=false
    username: root
    password: root

新的改变

spring:
  messages:
    encoding: UTF-8
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://172.16.17.103:3306/declaration?useUnicode=true&characterEncoding=utf-8&useSSL=false
    username: root
    password: root

serverTimezone

设定值为

serverTimezone=GMT%2B8

错误消失
