在Primefaces <p：ring>中使用图像

Question

我有一个primafaces ring.I想要用xhtml代码拍摄图像。我有一个论文库包括图像（paper1.jpg，paper2.jpg，.. paper12.jpg）。我不想使用ringview.java.I在p：ring标签之间添加了graphicimage标签。但是我没有显示图像。我该怎么办？

<h:form id="form">
    <p:ring id="custom" value="#{ringView.papers}" var="paper">
         <p:graphicImage id="img" name="papers/#{paper}" style="width:100%; height:100%"/>
    </p:ring>
</h:form>

RingView.java

@ManagedBean
public class RingView implements Serializable {

    private List<String> papers;
    private String selectedPaper;

    @PostConstruct
    public void init() {
        papers = new ArrayList<String>();
        for (int i = 1; i <= 12; i++) {
            papers.add("paper" + i + ".jpg");
        }
    }     
    public List<String> getPapers() {
        return papers;
    }     
    public void setPapers(List<String> papers) {
        this.papers = papers;
    }     
    public String getSelectedPaper() {
        return selectedPaper;
    }
    public void setSelectedCar(String selectedPaper) {
        this.selectedPaper = selectedPaper;
    }
}

我尝试过类似的事情：

<h:form id="form">
    <p:ring id="custom">
         <p:graphicImage id="img1" name="papers/paper1.jpg" style="width:100%; height:100%"/>
     <p:graphicImage id="img2" name="papers/paper2.jpg" style="width:100%; height:100%"/>
     <p:graphicImage id="img3" name="papers/paper3.jpg" style="width:100%; height:100%"/>
</p:ring>
