私の問題は、テーブルユーザーとテーブルグループがあることです（このテーブルはユーザーの承認に使用されます-ユーザーが管理者のようなグループに属している場合、彼らはadmincpにログインでき、他のユーザーはグループメンバーに属しています。 admincp にログインできません) 各ユーザーは多くのグループに属している可能性があり、各グループには多くのユーザーが含まれており、関係は多対多です。

永続ストレージに休止状態を使用します。ビジネスロジックを処理するためのStruts 2。

Struts2 からログイン アクションを実装したい場合、所属するグループ メンバーの値を取得するにはどうすればよいですか? 知りたい値と比較するには？

例

ユーザー名とパスワードからユーザーを取得し、ユーザークラスからグループを取得しますが、ユーザーが属するグループの値を取得する方法がわかりません

これは、Groupid に属するユーザーが 1 で、グループ テーブルの列の adminpermission が 1 の場合、そのユーザーは admincp にログインできることを意味します。

私のコード:

You could fetch user's groups with the following query:

SELECT u FROM User u INNER JOIN FETCH u.groups WHERE u.username = :name AND u.password = :password

Thus, you could access which groups has a user with user.getGroups()

As for your second question, I don't really think an Interceptor is required to implement login, but you will need it in order to prohibit access to all your pages when a user is not logged in, so maybe thats what you have seen.

ユーザーがログインしていることを期待するアクションを呼び出すときに、インターセプターを使用してログインを強制することをお勧めします。ユーザーがログインしておらず、アクションでユーザーがログインする必要がある場合、インターセプターはユーザーをログイン ページにリダイレクトします。 . ログインに成功すると、元の場所にリダイレクトできます。

この回答は、認証側のビットを説明しています: struts2 アプリケーションのセッション
