Question

您能告诉我如何使用jsf中的Primefaces为程序菜单添加f：setPropertyActionListener

public MenuBean() {  
        model = new DefaultMenuModel();  

        //First submenu  
        Submenu submenu = new Submenu();  
        submenu.setLabel("Dynamic Submenu 1");  

        MenuItem item = new MenuItem();  
        item.setValue("Dynamic Menuitem 1.1");  
        item.setUrl("#");  
        submenu.getChildren().add(item);  

        model.addSubmenu(submenu);  

        //Second submenu  
        submenu = new Submenu();  
        submenu.setLabel("Dynamic Submenu 2");  

        item = new MenuItem();  
        item.setValue("Dynamic Menuitem 2.1");  
        item.setUrl("#");  
        submenu.getChildren().add(item);  

        item = new MenuItem();  
        item.setValue("Dynamic Menuitem 2.2");  
        item.setUrl("#");  
        submenu.getChildren().add(item);  

        model.addSubmenu(submenu);  
    }

和

 <p:menu model="#{menuBean.model}"/>

Answer 1

要以编程方式执行此操作，它非常简单：

MenuItem item = new MenuItem();
item.addActionListener(listener);

我误解了你的问题吗？

Answer 2

import javax.faces.event.ActionListener;
import com.sun.faces.taglib.jsf_core.SetPropertyActionListenerImpl;
...
//setPropertyActionListener
                ValueExpression target = expFact.createValueExpression(elCtx, "#{TesterBean.someProperty}", String.class);
                ValueExpression value  = expFact.createValueExpression(strProperty, String.class);
                ActionListener handler = new SetPropertyActionListenerImpl( target , value );
                newCommandLink.addActionListener(handler);

f：p：menu（Primefaces）中项目的setPropertyActionListener
