Connection Java – MySQL : Public Key Retrieval is not allowed

You should add client option to your mysql-connector allowPublicKeyRetrieval=true to allow the client to automatically request the public key from the server. Note that allowPublicKeyRetrieval=True could allow a malicious proxy to perform a MITM attack to get the plaintext password, so it is False by default and must be explicitly enabled.

https://mysql-net.github.io/MySqlConnector/connection-options/

you could also try adding useSSL=false when you use it for testing/develop purposes

example:

jdbc:mysql://localhost:3306/db?allowPublicKeyRetrieval=true&useSSL=false
