JDBC MySQL Error: Access Denied for User 'root' @ 'localhost'

Introduction:

The exception "java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)" occurs when attempting to establish a database connection using JDBC with MySQL. This can arise due to incorrect configuration or insufficient privileges granted to the user trying to connect.

Cause:

The exception often indicates that the specified user ('root' in this case) does not have the necessary permissions or privileges to access the database. Insufficient user credentials or incorrect password provided can also lead to this error.

Solution:

To resolve this issue, ensure the following steps:

1. Correct User Credentials: Verify that the user name ('root' in this example) and password ('root' by default unless changed) are correct. Replace %password% with the actual password in the example given.
2. Grant Privileges: Grant the user ('root' in this case) sufficient privileges to access the database. This can be achieved using the following command:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '%password%' WITH GRANT OPTION;

3. Update Connection String: If the connection string (e.g., "jdbc:mysql://localhost/?user=root&password=rootpassword") does not include the updated credentials, modify it accordingly to reflect the changes.

Additional Tips:

• Ensure the MySQL server is running and listening on the correct port.
• Check if firewalls or other network configurations are blocking access to the database.
• Use a GUI tool or MySQL command line to execute the GRANT command.
• If the issue persists, consider checking the MySQL configuration files and user privileges.
