JAXB解組到實體錯誤

我解組XML流的實體的問題。我的外鍵永遠不會被設置爲具有正確主鍵的對象，它們只會被設置爲一個emtpy對象。JAXB解組到實體錯誤

與外鍵的類被稱爲ProductBase。它具有對品牌數據（字段pkId）和類別（字段pkId）的引用。當我解組並堅持時，我可以很好地處理BrandData和類別。我遇到了ProductBase的問題。

這裏是ProductBase：

@XmlAccessorType(XmlAccessType.PROPERTY)

    @NamedQuery(name = "ProductBase.findAll", query = "SELECT p FROM ProductBase p"),

    @NamedQuery(name = "ProductBase.findBySeriesName", query = "SELECT p FROM ProductBase p WHERE p.seriesName = :seriesName"), 
    @NamedQuery(name = "ProductBase.findByStatusCodes", query = "SELECT p FROM ProductBase p WHERE p.statusCodes = :statusCodes"), 
    @NamedQuery(name = "ProductBase.findByTs", query = "SELECT p FROM ProductBase p WHERE p.ts = :ts")}) 
public class ProductBase implements Serializable {

    public ProductBase(Integer pkId) {

    @XmlElement(name = "ts", required = true)

    @XmlTransient

    public void setProductEnhancementFeaturesCollection(Collection<ProductEnhancedFeatures> productEnhancementFeaturesCollection) { 
     this.productEnhancementFeaturesCollection = productEnhancementFeaturesCollection; 
    } 

    @XmlTransient 
    public Collection<SkuBasic> getSkuBasicCollection() { 
     return skuBasicCollection;

    @Override

     // TODO: Warning - this method won't work in the case the id fields are not set 
     if (!(object instanceof ProductBase)) { 
      return false; 
     } 
     ProductBase other = (ProductBase) object; 
     if ((this.pkId == null && other.pkId != null) || (this.pkId != null && !this.pkId.equals(other.pkId))) { 
      return false; 
     } 
     return true; 
    } 

    @Override 
    public String toString() { 
     return "entities.cmic.ajrs.com.ProductBase[pkId=" + pkId + "]"; 
    }

解組以下：

<ProductBase> 
<pkID>88294</pkID> 
<pkBrand>18</pkBrand> 
<pkCategory>35</pkCategory> 
<ColorsAvail>W</ColorsAvail> 
<StatusCodes/> 
<ts>1970-01-01T05:22:35.06</ts> 
</ProductBase>

我想用ProductBase對象，像這樣結束了：

ProductBase p1: 
p1.pkId=88294 
p1.brandData = (brandData object with pkId of 18) 
p1.categories = (Categories object with pkId of 35) 
p1.ts = (Date object with value 1970-01-01T05:22:35.06)

但是我得到

ProductBase p1： p1.pkId = 88294 p1.brandData =（品牌數據對象每個字段爲空） p1.categories =（類別對象每個字段爲空） p1.ts =（帶值爲1970-01-01T05的日期對象： 22：35.06）

所以，當我去堅持它與空值的問題ProductBase。

我希望這是由於在BradnData和分類實體不當引用。我嘗試使用@XmlInverseReference註釋，但沒有運氣。任何人都可以看到問題可能是什麼？

對於你將需要一個XmlAdapter這種使用情況。

import javax.xml.bind.annotation.adapters.XmlAdapter; 

public class BrandDataAdapter extends XmlAdapter<Integer, BrandData> { 

    @Override 
    public Integer marshal(BrandData arg0) throws Exception { 
     return arg0.getPkId(); 
    } 

    @Override 
    public BrandData unmarshal(Integer arg0) throws Exception { 
     return new BrandData(arg0); 
    } 

}

和ProductBase：

@JoinColumn(name = "pk_brand", referencedColumnName = "pk_id") 
@ManyToOne(optional = false, fetch = FetchType.LAZY) 
@XmlJavaTypeAdapter(BrandDataApter.class) 
private BrandData brandData;

謝謝你，我會檢查出來。我想知道JAXB有沒有很好的eclipselink參考。我剛剛看到@pace提到的地鐵引用，但並不確定是否有針對eclipselink實現的引用。 – grantk 2011-04-21 14:07:15

我帶領的EclipseLink JAXB實現（莫西）和我的博客是很好的參考：http://bdoughan.blogspot.com/。 MOXy組件的網站是：http://www.eclipse.org/eclipselink/moxy.php – 2011-04-21 14:11:59
