java我在Eclipse和MySQL之间的连接上有错误

Question

我用Eclipse编写了这段代码。我不明白为什么会发生以下错误。请给我一些建议

package test;
import java.sql.*;
public class ConnectionTest {
    public static void main(String[] args) {
        Connection conn = null;

        String url = "jdbc:mysql://localhost:3306/sqldb?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC";
        String NAME = "root";
        String PASSWORD = "Ekarlekarl1!";
        try {

            Class.forName("com.mysql.cj.jdbc.Driver");
            conn = DriverManager.getConnection(url, NAME, PASSWORD);
            System.out.println("connected");

        
        } catch (ClassNotFoundException e) {
            System.out.println("Fail");
        } catch (SQLException e) {
            System.out.println("Error: " + e);
        }
    }
}
