Question

我正在尝试掌握较新的编程模型（非Access Bean）。

在WebSphere Commerce 7 FEP 5中，如何计算从GetData标记中检索的对象的结构？

例如，在下面的代码段中，我如何知道catalogEntryDetails的数据结构是什么？班级名称，方法等？

还有人可以解释“metaData”字段的来源吗？应该是在名词定义中，还是在中介层的代码中设置的东西？我无法看到它作为名词定义中的直接字段的引用....

<c:forEach var="metadata" items="${catalogEntryDetails.metaData}" varStatus="status2">
    <c:if test="${metadata.key == 'ThumbnailPath'}">
        <c:set var="thumbNail" value="${env_imageContextPath}/${metadata.value}" />
    </c:if>         
    <c:if test="${metadata.key == 'FullImagePath'}">
        <c:set var="fullImage" value="${metadata.value}" />
    </c:if>
</c:forEach>

catalogEntryDetails对象是从此代码段设置的：

<c:if test="${!empty productId}">
    <%-- Try to get it from our internal hashMap --%>
    <c:set var="key1" value="${productId}+getCatalogEntryViewAllByID"/>
    <c:set var="catalogEntryDetails" value="${cachedCatalogEntryDetailsMap[key1]}"/>
    <c:if test="${empty catalogEntryDetails}">
        <wcf:getData type="com.ibm.commerce.catalog.facade.datatypes.CatalogNavigationViewType" var="catalogNavigationView" 
            expressionBuilder="getCatalogEntryViewAllByID" varShowVerb="showCatalogNavigationView" maxItems="1" recordSetStartNumber="0">
            <wcf:param name="UniqueID" value="${productId}"/>
            <wcf:contextData name="storeId" data="${storeId}" />
            <wcf:contextData name="catalogId" data="${catalogId}" />
        </wcf:getData>
        <wcf:set target = "${cachedCatalogEntryDetailsMap}" key="${key1}" value="${catalogNavigationView.catalogEntryView[0]}"/>
    </c:if>
</c:if>

<c:if test="${empty productId && !empty WCParam.partNumber}">
        <c:set var="key1" value="${WCParam.partNumber}+getCatalogEntryViewAllByPartnumber"/>
        <c:set var="catalogEntryDetails" value="${cachedCatalogEntryDetailsMap[key1]}"/>
        <c:if test="${empty catalogEntryDetails}">
            <wcf:getData type="com.ibm.commerce.catalog.facade.datatypes.CatalogNavigationViewType" var="catalogNavigationView" 
                expressionBuilder="getCatalogEntryViewAllByPartnumber" varShowVerb="showCatalogNavigationView" maxItems="1" recordSetStartNumber="0">
                <wcf:param name="PartNumber" value="${WCParam.partNumber}" />
                <wcf:contextData name="storeId" data="${storeId}" />
                <wcf:contextData name="catalogId" data="${catalogId}" />
            </wcf:getData>
            <c:set var="catalogEntryDetails" value="${catalogNavigationView.catalogEntryView[0]}"/>
            <wcf:set target = "${cachedCatalogEntryDetailsMap}" key="${key1}" value="${catalogNavigationView.catalogEntryView[0]}"/>
        </c:if>
</c:if>

您可以做的最好 - 检查IBM信息中心。 wcf:GetData文档告诉我们检索结果由“type”参数指定。在你的情况下，它是“com.ibm.commerce.catalog.facade.datatypes.CatalogNavigationViewType”。再次打开CatalogNavigationViewType的文档。文档告诉我们它的方法是getCatalogEntryView（）：

返回“目录条目视图”包含引用列表的值。列表内容的类型为CatalogEntryViewType。给定目录导航视图范围内的商品列表。

这就是你问题的答案： catalogEntryDetails是CatalogEntryViewType的一个实例。出于某种原因，我在IBM docs中找不到这个界面。但您仍然可以在com.ibm.commerce.catalog.facade.datatypes包中找到它（位于\ WCDE_ENT70 \ workspace \ WC \ Catalog-DataObjects.jar）

这是：

public interface CatalogEntryViewType

{

public abstract String getUniqueID();

public abstract void setUniqueID(String s);

public abstract String getPartNumber();

public abstract void setPartNumber(String s);

public abstract String getName();

public abstract void setName(String s);

public abstract String getThumbnail();

public abstract void setThumbnail(String s);

public abstract String getFullImage();

public abstract void setFullImage(String s);

public abstract String getShortDescription();

public abstract void setShortDescription(String s);

public abstract String getLongDescription();

public abstract void setLongDescription(String s);

public abstract String getManufacturer();

public abstract void setManufacturer(String s);

public abstract String getKeyword();

public abstract void setKeyword(String s);

public abstract boolean isHasSingleSKU();

public abstract void setHasSingleSKU(boolean flag);

public abstract void unsetHasSingleSKU();

public abstract boolean isSetHasSingleSKU();

public abstract String getSingleSKUCatalogEntryID();

public abstract void setSingleSKUCatalogEntryID(String s);

public abstract String getStoreID();

public abstract void setStoreID(String s);

public abstract List getAttachments();

public abstract List getPrice();

public abstract String getParentCatalogGroupID();

public abstract void setParentCatalogGroupID(String s);

public abstract String getParentCatalogEntryID();

public abstract void setParentCatalogEntryID(String s);

public abstract Map getMetaData();

public abstract UserDataType getUserData();

public abstract void setUserData(UserDataType userdatatype);

public abstract String getNumberOfSKUs();

public abstract void setNumberOfSKUs(String s);

public abstract List getSKUs();

public abstract List getComponents();

public abstract List getMerchandisingAssociations();

public abstract List getAttributes();

public abstract String getSubscriptionTypeCode();

public abstract void setSubscriptionTypeCode(String s);

public abstract String getDynamicKitURL();

public abstract void setDynamicKitURL(String s);

public abstract String getDynamicKitDefaultConfiguration();

public abstract void setDynamicKitDefaultConfiguration(String s);

public abstract boolean isDynamicKitDefaultConfigurationComplete();

public abstract void setDynamicKitDefaultConfigurationComplete(boolean flag);

public abstract void unsetDynamicKitDefaultConfigurationComplete();

public abstract boolean isSetDynamicKitDefaultConfigurationComplete();

public abstract String getDynamicKitModelReference();

public abstract void setDynamicKitModelReference(String s);

public abstract String getTitle();

public abstract void setTitle(String s);

public abstract String getMetaDescription();

public abstract void setMetaDescription(String s);

public abstract String getMetaKeyword();

public abstract void setMetaKeyword(String s);

public abstract String getFullImageAltDescription();

public abstract void setFullImageAltDescription(String s);

public abstract boolean isBuyable();

public abstract void setBuyable(boolean flag);

public abstract void unsetBuyable();

public abstract boolean isSetBuyable();

public abstract Object getCatalogEntryTypeCode();

public abstract void setCatalogEntryTypeCode(Object obj);

public abstract boolean isDisallowRecurringOrder();

public abstract void setDisallowRecurringOrder(boolean flag);

public abstract void unsetDisallowRecurringOrder();

public abstract boolean isSetDisallowRecurringOrder();

}

“metaData”字段来自此字符串：

public abstract Map getMetaData();

是的，你是对的，它来自业务对象介体配置中配置的名词定义：WC \ xml \ config \ com.ibm.commerce.catalog-fep \ wc-business-object-mediator.xml。默认情况下，它由SolrReadCatalogEntryViewPartMediator构建。从任何文档中我都不清楚我必须反编译才能搞清楚。有趣： - （

 <_config:part-mediator interfaceName="com.ibm.commerce.foundation.server.services.dataaccess.bom.mediator.ReadBusinessObjectPartMediator">
        <_config:part-mediator-implementation className="com.ibm.commerce.catalog.facade.server.services.dataaccess.bom.mediator.solr.SolrReadCatalogEntryViewPartMediator" />
        <_config:part-mediator-implementation className="com.ibm.commerce.catalog.facade.server.services.dataaccess.bom.mediator.solr.SolrReadCatalogGroupViewPartMediator" />
        <_config:part-mediator-implementation className="com.ibm.commerce.catalog.facade.server.services.dataaccess.bom.mediator.solr.SolrReadAttachmentAssetViewPartMediator" />
        <_config:part-mediator-implementation className="com.ibm.commerce.catalog.facade.server.services.dataaccess.bom.mediator.solr.SolrReadSuggestionViewPartMediator" />

        <_config:part-mediator-implementation className="com.ibm.commerce.catalog.facade.server.services.dataaccess.bom.mediator.solr.SolrReadWebContentViewPartMediator" />
        <!-- 
             Note: SolrReadCatalogNavigationViewPostMediator must be declared as the last entry.
        -->
<_config:part-mediator-implementation className="com.ibm.commerce.catalog.facade.server.services.dataaccess.bom.mediator.solr.SolrReadCatalogNavigationViewPostMediator" />
