MySQL 8.0 运行项目时，报错 Public Key Retrieval is not allowed 的解决办法

com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Public Key Retrieval is not allowed

在数据库的配置文件中（yml，或者properties文件）中配置数据源的位置加上&allowPublicKeyRetrieval=true就可以了

spring:
  profiles: dev
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: mysql
    url: jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
    platform: mysql
    schema: classpath:db/schema.sql
    data: classpath:db/data.sql
    # 每次重启都会根据data.sql schema.sql重建表数据, 设置 NEVER 就不启动重建
    # Each restart will rebuild the table data according to data.sql schema.sql
    # setting NEVER will not start the reconstruction
    initialization-mode: always
  jpa:
    database: mysql
    show-sql: true
