liferay - Liferay 6.1 中使用 Vaadin portlet 的 portlet 间通信

Question

我有一个需求，比如在 Liferay 中通信两个 vaadin portlet。一个 portlet 带有显示报告名称（webi 报告）的 vaadin 树视图。单击树时，我必须在另一个 portlet 中打开相应的报告。

任何人都可以提出您的想法并分享满足此要求的详细信息。

提前谢谢。

Answer 1

一种直接的解决方案是 Vaadin IPC 插件。在以下位置查看详细信息和示例：http: //vaadin.com/addon/vaadin-ipc-for-liferay

请注意，这需要使用 6.x 版本的 Vaadin。

import com.vaadin.ui.Window;

   public class receiveripc extends Application implements PortletListener {



     String name="";
     String data = "";
    public void init() {
        Window window = new Window("Vaadin Portlet Application");
        window.setName("sample");
        setMainWindow(window);
        window.addComponent(new Label("Hello Vaadin fgfgfgsgsdg!"));
        name=window.getName().toString();
        LiferayIPC liferayipc = new LiferayIPC();

        liferayipc.setImmediate(false);
        liferayipc.setWidth("200px");
        liferayipc.setHeight("200px");
        liferayipc.getDescription();


        liferayipc.addListener("eventid1", new LiferayIPCEventListener() {
            public void eventReceived(LiferayIPCEvent event)
            {
                // Do something with the message data

                data = event.getEventId();
             //  getMainWindow().

               getWindow(name).showNotification("Received hello: " + data);


          //     printData(window,data);

            }
        });
        window.addComponent(liferayipc);
        window.addComponent(new Label(data+"++++++++++gsdgsdgsdgsd++++++555Hello Vaadin hhfhhdfhdfh!"));
    //    window.addComponent(new Label(data+"++++Hello Vaadin usetttttttttttt!"));
    }

//       Window window1 = window;
//      return window1;
//  }

    protected void printData(Window window, String data) {
        // TODO Auto-generated method stub 
         window.addComponent(new Label(data + "Hello Vaadin userhghjgjgkjh!"));
    }

    @Override
    public void handleRenderRequest(RenderRequest request,
            RenderResponse response, Window window) {
        // TODO Auto-generated method stub

    }

    @Override
    public void handleActionRequest(ActionRequest request,
            ActionResponse response, Window window) {
        // TODO Auto-generated method stub

    }
