Troubleshooting "java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)"

The error "java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)" occurs when attempting to connect to a MySQL database using the root user with the provided credentials.

Cause:

This error is caused due to incorrect credentials or insufficient privileges for the root user on the specified host.

Solution:

To resolve this issue, you can try the following:

1. Verify Credentials: Ensure that the provided credentials, username (root) and password (rootpassword), are correct.
2. Grant Database Privileges: Grant the root user the necessary privileges on the target database. To do this, execute the following SQL statement:

<code class="sql">GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '%password%' WITH GRANT OPTION;</code>

Replace %password% with the actual password you want to use.

3. Reload Privileges: After granting the privileges, you need to reload the grant tables in MySQL. To do this, run the following command:

<code class="sql">FLUSH PRIVILEGES;</code>

4. Restart MySQL: Restart the MySQL service to apply the changes.
5. Update Connection String: Once privileges are granted to the root user, update your Java code to use the correct credentials and database name, as seen in the following example:

<code class="java">Class.forName("com.mysql.jdbc.Driver");
Connection m_connection = DriverManager.getConnection("jdbc:mysql://localhost/?user=root&password=rootpassword&database=databasename");</code>

By following these steps, you should be able to establish a successful connection to the MySQL database as the root user.
