问题概述
关于这个是在新开子工程中遇到的,本工程使用的Mysql 8.x的,拉取项目启动时遇见问题:
“ com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Public Key Retrieval is not allowed ”

解决办法
查了下官网的参数操作表,如下图:
意为:
如果用户使用了 sha256_password 认证,密码在传输过程中必须使用 TLS 协议保护,但是如果 RSA 公钥不可用,可以使用服务器提供的公钥;可以在连接中通过 ServerRSAPublicKeyFile 指定服务器的 RSA 公钥,或者 AllowPublicKeyRetrieval=True 参数以允许客户端从服务器获取公钥;但是需要注意的是 AllowPublicKeyRetrieval=True可能会导致恶意的代理通过中间人攻击(MITM)获取到明文密码,所以默认是关闭的,必须显式开启。
根据官方的描述,只需要在数据库的链接后面新增 “ allowPublicKeyRetrieval=true ” 即可解决,
内容如下:
spring:
datasource:
url:
jdbc:mysql://***.***.***.***:3306/database_name?useUnicode=true
&characterEncoding=UTF-8
&useSSL=false
&serverTimezone=Asia/Shanghai
&useSSL=false
&allowPublicKeyRetrieval=true
再次拉起项目即可成功启动了!!!
