Question

这是我的代码-

公共类DataBaseConnection {

    public static void main(String[] args) throws ClassNotFoundException, SQLException {

        Class.forName("com.mysql.cj.jdbc.Driver");

        Connection con= DriverManager.getConnection("jdbc:mysql://localhost:3306/nitya", "username", "password");

        Statement s=con.createStatement();

        ResultSet r=s.executeQuery("select * from employee");

        while(r.next()) {
        System.out.println(r.getInt(1));
        }


    }

}

我遇到的错误-

Exception in thread "main" java.sql.SQLException: Access denied for user 'ss'@'localhost' (using password: YES)

MS SQL已在本地安装并且可以正常工作。但是在默认端口localhost：3306中，它没有打开。您能否分享我应该在getconnect方法中提供的网址？ @CrazyMerlin 14
