mysql.cj.exceptions.UnableToConnectException: Public Key Retrieval is not allowed

mysql.cj.exceptions.UnableToConnectException: Public Key Retrieval is not allowed 是一个MySQL连接异常。这个异常表示无法进行公钥检索。为了解决这个问题，可以在MySQL的连接URL中增加参数allowPublicKeyRetrieval=true。例如，jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true。这样设置后，就能够允许公钥检索，解决了异常问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
