< p：menuitem value =Kobe Bryanturl =＃/> 
< / p：breadCrumb> 
  

解决方案

BreadCrumb作为模型属性。这一个用于从原始文档（Mainplace Documentation）中的MenuBar动态创建menuitem（您已经不用了，为了适应BreadCrumb）：

  public class MenuBean {
 private MenuModel model; 
 
 public MenuBean（）{
 model = new DefaultMenuModel（）; 
 //第一个子菜单
 DefaultSubMenu firstSubmenu = new DefaultSubMenu（Dynamic Submenu）; 
 DefaultMenuItem item = new DefaultMenuItem（External）; 
 item.setUrl（http://www.primefaces.org）; 
 item.setIcon（ui-icon-home）; 
 firstSubmenu.addElement（item）; 
 model.addElement（firstSubmenu）; 
 //第二个子菜单
 DefaultSubMenu secondSubmenu = new DefaultSubMenu（Dynamic Actions）; 
 item = new DefaultMenuItem（Save）; 
 item.setIcon（ui-icon-disk）; 
 item.setCommand（＃{menuBean.save}）; 
 item.setUpdate（messages）; 
 secondSubmenu.addElement（item）; 
 item = new DefaultMenuItem（Delete）; 
 item.setIcon（ui-icon-close）; 
 item.setCommand（＃{menuBean.delete}）; 
 item.setAjax（false）; 
 secondSubmenu.addElement（item）; 
 item = new DefaultMenuItem（Redirect）; 
 item.setIcon（ui-icon-search）; 
 item.setCommand（＃{menuBean.redirect}）; 
 secondSubmenu.addElement（item）; 
 model.addElement（secondSubmenu）; 
} 
 
 public MenuModel getModel（）{
 return model; 
} 
} 
  

此后，您只需像这样调用模型在你的面包屑里面：

  model =＃{menuBean.model}
  / pre> 
 
 
  
 
I'm using primefaces and want to add a breadcrumb menu.
How should I load my breadcrumb dynamically?
What advise or experience do you have?
<p:breadCrumb>
    <p:menuitem value="Categories" url="#" />
    <p:menuitem value="Sports" url="#" />
    <p:menuitem value="Basketball" url="#" />
    <p:menuitem value="NBA" url="#" />
    <p:menuitem value="Teams" url="#" />
    <p:menuitem value="L.A. Lakers" url="#" />
    <p:menuitem value="Roster" url="#" />
    <p:menuitem value="Kobe Bryant" url="#" />
</p:breadCrumb>
Documentation to primefaces
 解决方案 
BreadCrumb as a model in attribute. This one serve to create menuitem dynamically like this example for MenuBar from Primefaces Documentation (You have off course, to adapt this one for BreadCrumb):
public class MenuBean {
    private MenuModel model;

    public MenuBean() {
        model = new DefaultMenuModel();
        // First submenu
        DefaultSubMenu firstSubmenu = new DefaultSubMenu("Dynamic Submenu");
        DefaultMenuItem item = new DefaultMenuItem("External");
        item.setUrl("http://www.primefaces.org");
        item.setIcon("ui-icon-home");
        firstSubmenu.addElement(item);
        model.addElement(firstSubmenu);
        // Second submenu
        DefaultSubMenu secondSubmenu = new DefaultSubMenu("Dynamic Actions");
        item = new DefaultMenuItem("Save");
        item.setIcon("ui-icon-disk");
        item.setCommand("#{menuBean.save}");
        item.setUpdate("messages");
        secondSubmenu.addElement(item);
        item = new DefaultMenuItem("Delete");
        item.setIcon("ui-icon-close");
        item.setCommand("#{menuBean.delete}");
        item.setAjax(false);
        secondSubmenu.addElement(item);
        item = new DefaultMenuItem("Redirect");
        item.setIcon("ui-icon-search");
        item.setCommand("#{menuBean.redirect}");
        secondSubmenu.addElement(item);
        model.addElement(secondSubmenu);
    }

    public MenuModel getModel() {
        return model;
    }
}
After this you have just to call the model like this inside your  breadcrumb :
model="#{menuBean.model}"
Primeface documentation
