現在ログイン中のユーザーと一致する行の編集・削除ボタンを押下した場合エラーが出るようにしたい

実現したいこと

現在ログイン中のユーザーと一致する行の編集・削除ボタンを押下した場合エラーが出るようにさせたいです。

private boolean checkUser(HttpServletRequest request, HttpSession session) {

    boolean check = false;

    // ログイン中ユーザーの編集は不可
    UserMenteDto globalUserDto = (UserMenteDto)session.getAttribute("globalUser");

    if (globalUserDto.getShainNo().equals(Integer.valueOf(request.getParameter("shainNo")))) {
        request.setAttribute("message", "ログイン中のユーザーです");
        check = true;
    }

    return check;
}

こんなのも考えてみたのですが
しかしこの三つになんと記述していいかわかりません
HttpServletRequestを使えばできそうなんですが
なのでどなたかご指摘をお願いいたします。

現在ログイン中のユーザーと一致する行の編集・削除ボタンを押下した場合

とのことなので、削除処理と編集処理を実装している箇所に実装すれば良いでしょう。

実装されている内容を見た限りでは

java
1if (request.getParameter("deleteNo") != null && !request.getParameter("deleteNo").equals("")) {

の中が削除処理のようです。
