私のツアー ("tournee") に基づいて、クラスのトーナメント (profil_tournee) リストで自分のプロファイルを取得したいと考えています。ただし、私には例外があります。誰でも私を助けることができますか？

スレッド「AWT-EventQueue-0」の例外 java.lang.IllegalArgumentException: TypedQuery に指定された型 [fr.galettedebroons.domain.Profil] は、クエリの戻り値の型 [interface java.util.Collection] と互換性がありません

リクエスト：

 List<List<Profil>> listProfil = Arrays.asList(manager_.createQuery("select t.profil_tournee "
            + "FROM Tournee t WHERE t.nom LIKE :tournee", Profil.class)
            .setParameter("tournee", tournee)
            .getResultList());

モデル ：

あなたのエラーは、メソッドを呼び出すときに戻り値の型が宣言された型と一致している必要があるというヒントを与えてくれますEntityManager.createQuery(query, Type):

List<SomeType> em.createQuery("SELECT s FROM SomeType", SomeType.class);

ただし、実際の問題は、クエリが違法であることです。JPA では、コレクション値式を SELECT 句の一部にすることはできません。私の別の回答をご覧ください https://stackoverflow.com/a/25890863/3796586。

あなたの場合の解決策は、次のようにクエリを逆にすることです。

List<Profil> result = em.createQuery("SELECT p FROM Profil p WHERE" +
    "p.profil_tournee.norm LIKE :tournee", Profil.class)
        .setParameter("tournee", tournee)
        .getResultList());

期待される結果リストには、プロファイルではなく、プロファイルのリストである要素が含まれます。

クエリの作成のために、Profil.class を List.class に置き換えます。

List<List<Profil>> listProfil = Arrays.asList(manager_.createQuery("select t.profil_tournee "
        + "FROM Tournee t WHERE t.nom LIKE :tournee", List.class)
        .setParameter("tournee", tournee)
        .getResultList());
