Một trong những:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...và một trong những cái còn lại:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

Trong giao thức HTTP, bạn có thể giao tiếp trong mỗi đường dẫn sử dụng một (hoặc nhiều) trong các "phương thức này".

#### Operation

ここでの「オペレーション」とは、HTTPの「メソッド」の1つを指します。

以下のようなものの1つ:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...さらによりエキゾチックなもの:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

HTTPプロトコルでは、これらの「メソッド」の1つ（または複数）を使用して各パスにアクセスできます。

APIを構築するときは、通常、これらの特定のHTTPメソッドを使用して特定のアクションを実行します。

通常は次を使用します:

* `POST`: データの作成
* `GET`: データの読み取り
* `PUT`: データの更新

        // Both instances should be of the same class
        assertEquals(exception1.getClass(), exception2.getClass());
    }

        // Test that stack trace is properly populated
        InvalidAccessTokenException exception = new InvalidAccessTokenException("JWT", "Invalid signature");

                log.trace("Got subject " + s);

                + e.getClass().getName() + "\n" + "Message: "
