私は多くの場所を検索しましたが、以下のエラーの解決策が見つかりませんでした：

例外は、次のSpringxmlファイル構成からのものです。

あなたからまだ連絡がありませんが、私はここで手足を出すつもりです

通常、Hibernate DAO オブジェクトの場合、dataSource ではなく sessionFactory が必要です。そのため、DAO に sessionFactory を設定する方法を提供します (たとえば、セッターまたはコンストラクター - 変更可能である必要がないため、コンストラクターを好みます)。

public class HibernateDaoImpl implements HibernateDao
{
   private SessionFactory sessionFactory;

   public HibernateDaoImpl(SessionFactory sessionFactory)
   {
     this.sessionFactory = sessionFactory;
   }
}

設定

 <bean id="hibernateDaoImpl" class="com.springhibernate.example.HibernateDaoImpl">
   <constructor-arg ref="sessionFactory"/>
 </bean>
