[MySQL] Loading class 'com.mysql.jdbc.Driver'. This is deprecated.

오류메세지

public static Connection getConnection() {
        try {
            Class.forName("com.mysql.cj.jdbc.Driver").newInstance();
            return DriverManager.getConnection("jdbc:mysql://localhost:3306/db", 
                    "id", "pw");
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
