これが私のクラスです：

 public class DataModel implements ApiConstants, 

 DataConstants,IDataModelWrapper {     
  }

ApiConstants、DataConstants、IDataModelWrapperは単純なインターフェイスです。シリアル化可能なインターフェイスを実装する必要がありますか？

どんな助けでもありがたいです。

オブジェクトをセッションに追加するときはいつでも、常にそれを作成する必要がありますSerializable。

これには次の 2 つの目的があります。

  • 頻繁にアクセスされない場合、コンテナはセッションをディスクに保存できます
  • コンテナが同じクラスタのノード間でセッション データを共有できるようにします
