Embedded Undertown 同时部署 websocket 和 servlet,不工作
Embedded Undertown deploy websocket and servlet at same time, not work
我是 undertow 的新手,我正在开发一个独立的应用程序,将其用作嵌入式服务器。我希望我可以在我的嵌入式 undertow 中部署网络套接字、servlet 和 restfull htmls 服务。
到目前为止,我只用 web 套接字和 servlet 完成了测试,问题是每个单独的功能都正常,但将它们部署在一起时,我无法从测试页面访问 HTML 和 JavaScript,如果我删除 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
与 'ws://localhost:8080/fermat/node-channel' 的 WebSocket 连接失败:WebSocket 握手期间出错:意外的响应代码:404
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,还将添加对其他技术的支持,例如:
- WebSocket
- Resteasy
- 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);
