にキャストすることはできませんが、私は春+休止状態に非常に新しいです、と私は私のDAOが動作しているかどうかを確認するためのテストを実行しています。私は次のエラーをGoogleで検索すると、多くの異なる答えを得ます（主に私がチェックしたタイプミス）。私はあなたがこの上で私を助けることができる願っています：エラーテストのDAO：sun.reflect.generics.reflectiveObjects.TypeVariableImplはjava.lang.Classの

これを引き起こす可能性がありますか？私がAbstractHibernateDAOとNominationHibernateDAOで編集しているかどうか教えてください。
ありがとうございました！ここ
編集スニペットです：
これはAbstractHibernateDAOためのスニペットで、ライン50は、コメントである：
：public abstract class AbstractHibernateDAO<T, K extends Serializable>
implements DAO<T, K> {
protected Logger logger = LoggerFactory.getLogger(this.getClass());
private SessionFactory sessionFactory;
private Class<T> persistentClass;
protected AbstractHibernateDAO(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
this.persistentClass = (Class<T>) ((ParameterizedType) //LINE 50
getClass().getGenericSuperclass()).getActualTypeArguments()[0];
}
ライン36はNominationHibernateDAOため、このスニペットにコメントが続いています
@Repository("nominationDao")
public class NominationHibernateDAO<T extends Nomination>
extends AbstractHibernateDAO<T,Integer>
implements NominationDAO<T> {
@Autowired(required = true)
public NominationHibernateDAO(SessionFactory sessionFactory) {
super(sessionFactory); //LINE 36
}
私はコードを見る必要があります.... – hvgotcodes
@hvgotcodesエラーが指し示していた箇所にスニペットを追加しました – Nimchip
あなたのjunitテストでアプリケーションコンテキストをどのように読み込んでいるかを表示できますか？ – dimitrisli
