primefaces - Primefaces 菜单栏 actionListener

Question

嗨，我有一个 p:manubar

 <p:menubar model="#{topMenu.model}"/>

我想在动作事件上调用动作监听器并存储活动选项卡。我怎么能那样做？这是我的模型豆

@ManagedBean(name = "topMenu")
@RequestScoped

public class TopMenuBean {

public MenuModel model;
private UIViewRoot viewRoot;
private final MenuHelper menuHelper = new MenuHelper();

@PostConstruct
public void initModel() {

    model = new DefaultMenuModel();
    viewRoot = FacesContext.getCurrentInstance().getViewRoot();

    String viewId = viewRoot.getViewId();

    model.addMenuItem(menuHelper.itemMenuCreator(viewId, null, "Dashboard", "/pages/list.xhtml"));
    model.addMenuItem(menuHelper.itemMenuCreator(viewId, null, "Configuration", "/pages/config.xhtml"));
}

public MenuModel getModel() {
    return model;
}
}

有没有人有一些想法如何实现这个？

您可以使用方法 MenuItem.addActionListener(ActionListener) 将实现 ActionListener 接口的类的对象添加到菜单项，如下所示：

menuItem.addActionListener(actionListener);
