Question

我是新用的，我正在开发一个独立的应用程序，将其用作嵌入式服务器。我希望我可以在嵌入式软件中部署Web套接字，servlet和restfull htmls服务。

到目前为止，我只使用网络套接字和servlet进行了测试，每个单独的功能都正常运行，但是将它们部署在一起的Web套接字不是我从带有HTML和JavaScript的测试页面访问的，如果我删除了servlet页面nigun测试运行没有错误。

这是我的代码：

    /*
     * Create the  appWebSocketDeploymentInfo and configure
     */
    WebSocketDeploymentInfo appWebSocketDeploymentInfo = new WebSocketDeploymentInfo();
    appWebSocketDeploymentInfo.setBuffers(new ByteBufferSlicePool(BufferAllocator.BYTE_BUFFER_ALLOCATOR, 17000, 17000 * 16));
    appWebSocketDeploymentInfo.addEndpoint(WebSocketEndpoint1.class);
    appWebSocketDeploymentInfo.addEndpoint(WebSocketEndpoint2.class);

    /*
     * Create the  appDeploymentInfo and configure
     */
    DeploymentInfo appDeploymentInfo = Servlets.deployment()
                                    .setClassLoader(Server.class.getClassLoader())
                                    .setContextPath("/myapp)
                                    .setDeploymentName("app.war")
                                    .setResourceManager(new FileResourceManager(new File("src/main/webapp"), 1024))
                                    .addServlets(Servlets.servlet("HomeServlet", HomeServlet.class).addMapping("/home"))
                                    .setResourceManager(new ClassPathResourceManager(Server.class.getClassLoader(), Server.class.getPackage()))
                                    .addServletContextAttribute(WebSocketDeploymentInfo.ATTRIBUTE_NAME, appWebSocketDeploymentInfo);

    /*
     * Create the deploymentManager
     */
    deploymentManager = Servlets.defaultContainer().addDeployment(appDeploymentInfo);

    /*
     * Deploy the app
     */
    deploymentManager.deploy();

    /*
     * Create the path handle
     */
    pathHandler = Handlers.path(Handlers.redirect("/myapp/home")).addPrefixPath("/myapp", deploymentManager.start());

    /*
     * Create the server
     */
    undertowServer = Undertow.builder().addHttpListener(DEFAULT_PORT, DEFAULT_IP).setHandler(pathHandler).build();

javascript日志错误是

经过广泛的测试和研究，我得到了正确的配置和启动服务器的方法，还将增加对其他技术的支持，例如：

的WebSocket
RestEasy的
焊接

我的最终代码：

UndertowJaxrsServer server = new UndertowJaxrsServer();
Undertow.Builder serverBuilder = Undertow.builder().addHttpListener(DEFAULT_PORT, DEFAULT_IP);
ServletContainer servletContainer = Servlets.defaultContainer();

   /*
    * Create the App WebSocketDeploymentInfo and configure
    */
    WebSocketDeploymentInfo appWebSocketDeploymentInfo = new WebSocketDeploymentInfo();
    appWebSocketDeploymentInfo.setBuffers(new    ByteBufferSlicePool(BufferAllocator.BYTE_BUFFER_ALLOCATOR, 17000, 17000 * 16));
    appWebSocketDeploymentInfo.addEndpoint(WebSocketNodeChannelServerEndpoint.class);
    appWebSocketDeploymentInfo.addEndpoint(WebSocketClientChannelServerEndpoint.class);

    /*
     * Create the App ResteasyDeployment and configure
     */
    ResteasyDeployment deployment = new ResteasyDeployment();
    deployment.setApplicationClass(JaxRsActivator.class.getName());
    deployment.setInjectorFactoryClass("org.jboss.resteasy.cdi.CdiInjectorFactory");

    /*
     * Create the App DeploymentInfo and configure
     */
    DeploymentInfo appDeploymentInfo  = server.undertowDeployment(deployment, APP_NAME);
    appDeploymentInfo.setClassLoader(FermatEmbeddedNodeServer.class.getClassLoader())
                    .setContextPath(APP_NAME)
                    .setDeploymentName(WAR_APP_NAME)
                    .addServletContextAttribute(WebSocketDeploymentInfo.ATTRIBUTE_NAME, appWebSocketDeploymentInfo)
                    .addServlets(Servlets.servlet("HomeServlet", HomeServlet.class).addMapping("/home"))
                    .addListeners(Servlets.listener(org.jboss.weld.environment.servlet.Listener.class));

    server.deploy(appDeploymentInfo);
    server.start(serverBuilder);

Embedded Undertown同时部署websocket和servlet，无法正常工作
