java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed

mysql8.x版本的数据库在连接的时候报错java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed 只要在url的后边加上allowPublicKeyRetrieval=true即可 

jdbc:mysql://localhost:3306/test?useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true
