如何在jsf中将Primefaces Galleria与用户定义的对象一起使用

Question

我想将当前的缩放库转换为Prime-faces画廊。我有以下代码。

1）profile.xhtml

<div class="profileImageDiv">
       <em:zoomGalleria showDocName="true" value="#{thumbImageMBean.documentReferenceThumbs}" />
        <a href="#{request.contextPath}/ui/ImageServlet?genericProfileDocRefId=#{generalEnquiryMBean.profileDocRefId}&amp;name=abc.jpg"
           class="group1">
          <h:graphicImage title="#{generalEnquiryMBean.profileDocRefId}"
                  value="/ui/ImageServlet?name=abc.jpg&amp;docRefId=#{generalEnquiryMBean.profileDocRefId}&amp;thumb=true"
                  alt="" width="137" height="138"/>
        </a>
      </div>

2）ThumbImageBean.java

@ManagedBean
@CustomScoped(value = "#{customScope}")
public class ThumbImageMBean extends BaseBean{


  ZoomGalleriaModel documentReferenceThumbs;

    public void setDocumentReferenceThumbs(ZoomGalleriaModel documentReferenceThumbs){
    this.documentReferenceThumbs = documentReferenceThumbs;
  }
 public ZoomGalleriaModel getDocumentReferenceThumbs() {
    return this.documentReferenceThumbs;
  }

3）ZoomgalleriaModel

 public class ZoomGalleriaModel {
  private List<GalleriaDocument> documentList;
  //setter getter 
    public void addGalleriaDocument(GalleriaDocument galleriaDocument){
    documentList.add(galleriaDocument);
  }

4）GalleriaDocument

  public class GalleriaDocument implements Serializable{

  private long docRefId;
  private String docDescription;
  private byte[] document;
  private Date documentDate;
  private String userName;
//setter and getter and constructor
  }

我尝试通过以下代码使用Primefaces Galleria。 PrimeFaces Galleria code

<p:galleria value="#{thumbImageMBean.documentReferenceThumbs.documentList.toArray()}"     var="galleriaDoc" panelWidth="500" panelHeight="313" showCaption="true"> //primefaces galleria required array of string but i had List of objects   

    <p:graphicImage name="demo/images/nature/#{galleriaDoc}" alt="Image Description for #{galleriaDoc}" title="#{galleriaDoc}"/>
</p:galleria>

但是它不起作用，我不是JSF专家，所以要感谢每个建议。

PS：PrimeFaces版本3.0

Answer 1

看起来您的documentList是List<GalleriaDocument>。对于初学者，您可能会失去toArray（）。

Answer 2

Primefaces galleria接受String（图像名称）列表，并且您正在传递对象列表。您可以将其转换为String（docRefId的列表）

Answer 3

以下代码对我有用，但是description（title + date）没有显示。 PrimeFaces版本为3.1
