在数据库连接的地方，加上

allowPublicKeyRetrieval=true

下面是我的全量配置

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/door?autoReconnect=true&useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false&allowMultiQueries=true&allowPublicKeyRetrieval=true
    username: root
    password: 123456
