无法在hibernate JPA中检索大孩子

Question

Configuration有article type个孩子，article types可能有article types个孩子。
我正在尝试检索所有configuration及其子级（article type的所有configuration）。
我不会在这里找到父母和孩子article type 我想通过使用配置实体来检索所有授予子项。

这是我的configuration实体： -

@Entity
@Table(name = "tbl_configuration")
@XmlRootElement
public class Configuration extends BaseEntity implements Serializable
{
    private static final long                   serialVersionUID    = 1L;

    @Id
    @Basic(optional = false)
    @Column(name = "config_index")
    private Integer                             configIndex;

    @Column(name = "config_nom")
    private String                              configNom;

    @Column(name = "config_revision")
    private String                              configRevision;

    @JsonManagedReference(value="configuration-article-type")
    @OneToMany(mappedBy = "artTypPcIndexConfig", fetch = FetchType.EAGER)
    private Collection<ArticleTypeParentChild>  articleTypeParentChildCollection;

    public Configuration()
    {
    }

    public Configuration(Integer configIndex)
    {
        this.configIndex = configIndex;
    }

    public Integer getConfigIndex()
    {
        return configIndex;
    }

    public void setConfigIndex(Integer configIndex)
    {
        this.configIndex = configIndex;
    }

    public String getConfigNom()
    {
        return configNom;
    }

    public void setConfigNom(String configNom)
    {
        this.configNom = configNom;
    }

    public String getConfigRevision()
    {
        return configRevision;
    }

    public void setConfigRevision(String configRevision)
    {
        this.configRevision = configRevision;
    }



    public Collection<ArticleTypeParentChild> getArticleTypeParentChildCollection()
    {
        return articleTypeParentChildCollection;
    }

    public void setArticleTypeParentChildCollection(Collection<ArticleTypeParentChild> articleTypeParentChildCollection)
    {
        this.articleTypeParentChildCollection = articleTypeParentChildCollection;
    }

}

ArticleTypeParentChild表实体

@Entity
@Table(name = "tbl_article_type_parent_child")

    private static final long   serialVersionUID    = 1L;

        this.artTypePcIndex = artTypePcIndex;
    }

    public Integer getArtTypePcIndex()
    {

    }

    public void setArtTypePcIndex(Integer artTypePcIndex)
    {
        this.artTypePcIndex = artTypePcIndex;
    }   

    public ArticleType getArtTypChildIndex()
    {
        return artTypChildIndex;
    }

    public void setArtTypChildIndex(ArticleType artTypChildIndex)
    {
        this.artTypChildIndex = artTypChildIndex;
    }

    public ArticleType getArtTypParentIndex()
    {
        return artTypParentIndex;
    }

    public void setArtTypParentIndex(ArticleType artTypParentIndex)
    {
