Public Key Retrieval is not allowed error solution

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

after restarting the application when using MySQL 8.0

In the login function, after entering the correct account password, click login, instead of jumping to the corresponding interface, an error of http 500 is reported

The solution is to add allowPublicKeyRetrieval=true

to the url connecting to the database
