休眠嵌套條件為空結果

Question

問題是當我應該獲取一些元素時，我在查詢中得到空結果。 這是代碼：

DetachedCriteria criteria = DetachedCriteria.forClass(Article.class);
DetachedCriteria authorCriteria = criteria.createCriteria("author");
authorCriteria.add(Restrictions.eq("id",((User)session.getAttribute("user")).getId()));
List<Article> articles = articleManager.findArticleByCriteria(criteria);


@Entity
@Table(name = "ARTICLES")
public class Article {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    Integer id;
    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "author_fk")
    Writer author;
    @Column(length = 10000)
    String content;
    String title;
    @Transient
    String shortContent;
    ... 
}

我希望獲得特定作者的文章。

好的，我發現了問題：

public List<Article> findByCriteria(DetachedCriteria criteria){
    List<Article> articles = null;
    articles = criteria.getExecutableCriteria(HibernateUtil.getSession()).list();
//return value wasn't assignet do articles
    return articles;


}

謝謝大家的承諾:)

您正在通過作者標准，而不是通過根標准。 代碼應為：

List<Article> articles = articleManager.findArticleByCriteria(criteria);
