Websocket JSR-356 falla con Jetty 9.4.1

embedded-jetty jetty-9

Question

Mi servidor web actual está integrado Jetty 9.1.5. Funciona bien con JSR-356 para crear websocket. En estos días, estoy tratando de actualizar a Jetty 9.4.1. Todo funciona bien excepto websocket.
Mi código como a continuación:

1. Embedded Jetty y Websocket libs:

<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
<version>9.4.1.v20170120</version>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-webapp</artifactId>
<version>9.4.1.v20170120</version>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-annotations</artifactId>
<version>9.4.1.v20170120</version>
</dependency>
<dependency>
<groupId>org.eclipse.jetty.websocket</groupId>
<artifactId>javax-websocket-server-impl</artifactId>
<version>9.4.1.v20170120</version>
</dependency>

2. Punto final del servidor:

 @ServerEndpoint(value = "/ws/communication/{officeId}/{username}/{oldWSSession}")
class WSCommunication {
// @OnOpen, @OnMessage, @OnClose methods
}

3. Jetty server, contexto de Webapp, configuración de Websocket:

    // Jetty server
   Server server = new Server();
   String[] configFiles = {"./etc/jetty.xml"};
   for (String configFile : configFiles) {
   XmlConfiguration configuration = new XmlConfiguration(new File(configFile).toURI().toURL());
   configuration.configure(server);
   Connector[] connectors = server.getConnectors();
   if (connectors != null && connectors.length == 2) {
   ServerConnector serverConnector = (ServerConnector) connectors[1];
   serverConnector.setPort(8443);
   }
   }
   // Webapp context
   WebAppContext webContext = new WebAppContext(ResourceManager.getWebappsPath(), "/myContext");
   webContext.setContextPath("/myContext");
   webContext.setResourceBase(ResourceManager.getWebappsPath() + contextPath);
   webContext.setInitParameter("org.eclipse.jetty.servlet.Default.dirAllowed", "false");
   private List<WebAppContext> listWebContext = new ArrayList<>();
   listWebContext.add(webContext);
   ContextHandlerCollection contexts = new ContextHandlerCollection();
   contexts.setHandlers(listWebContext.toArray(new WebAppContext[listWebContext.size()]));
   server.setHandler(contexts);
   // Start server
   server.start();
   // Websocket
   ServerContainer container =
   WebSocketServerContainerInitializer.configureContext(webContext);
   container.addEndpoint(webContext.getClassLoader().loadClass(
   "com.example.WSCommunication"));
   container.setDefaultMaxSessionIdleTimeout(84600);
   // Dump server log
   server.dumpStdErr();

El código anterior funciona bien con Jetty 9.1.5.v20140505 y Java 7, pero falla cuando actualizo a Jetty 9.4.1.v20170120 y Java 8. La consola del navegador informa un error 404.

WebSocket connection to ''wss://localhost:8443/myContext/ws/communication/5/kbui/None'' failed: Unexpected response code: 404

¿Perdí algo cuando actualicé Jetty?
Gracias por adelantado.

Answer 1

A juzgar por su configuración, terminará con ...

wss://localhost:8443/myContext/ws/communication/5/kbui/None

Tu contextPath no es /context , es realmente /myContext en tu configuración.

Cortaste la sección Asignaciones de servlets en el volcado (esa fue la parte importante. Heh)

Pero intentar agregar manualmente el WSCommunication final de WSCommunication contenido en WebAppContext desde fuera de WebAppClassloader o ServletContext de WebApp probablemente también sea un problema.

Tienes 3 opciones:

1. El modo automático JSR356

   Configure el descubrimiento de anotación y exploración de bytecode para su WebAppContext y permita que el inicio descubra y cargue automáticamente el WSCommunication final de WSCommunication .

   Agregue lo siguiente a su webContext ...

webContext.setAttribute("org.eclipse.jetty.websocket.jsr356",Boolean.TRUE);
webContext.setConfigurations(new Configuration[] {
new AnnotationConfiguration(),
new WebXmlConfiguration(),
new WebInfConfiguration(),
new PlusConfiguration(),
new MetaInfConfiguration(),
new FragmentConfiguration(),
new EnvConfiguration()});

Y agregue la dependencia de jetty-annotations a su proyecto.

2. El manual de JSR356

   Use javax.websocket.server.ServerApplicationConfig para informar que WSCommunication está disponible para agregarse desde el inicio de la aplicación de Internet.

3. El manual de especificaciones de Servlet Way

   Este es el enfoque más fácil. Cree un javax.servlet.ServletContextListener que agregue el WSCommunication final de ServerContainer al ServerContainer

public class MyContextListener implements ServletContextListener
{
@Override
public void contextDestroyed(ServletContextEvent sce)
{
}
@Override
public void contextInitialized(ServletContextEvent sce)
{
ServerContainer container = (ServerContainer)sce.getServletContext()
.getAttribute(ServerContainer.class.getName());
try
{
container.addEndpoint(WSCommunication.class);
}
catch (DeploymentException e)
{
throw new RuntimeException("Unable to add endpoint",e);
}
}
}
