セッションを使用せずに、あるアクションから別のアクションにパラメーターを渡す必要があります。コードは次のとおりです。スコープインターセプターを使用しようとしています。これが私のコードです。何が間違っているのかわかりませんが、結果を得ることができません。

他のすべてのアクションでセッションオブジェクトをインスタンス化していますよね?

ServletActionContext から取得しているだけです。

セッションの入れ方

ServletActionContext.getContext().getSession().put("softuser", someUserObject);

セッションから取得する方法

ServletActionContext.getContext().getSession().get("softuser");
