Atmosphäre ist nicht in der Lage zu konfigurieren JSR-356

Question

Ich erstellte Java-Webanwendung und versuchen, Atmosphäre zu JSR-356 zu verwenden, da, wie ich verstand, ist es die einzige Möglichkeit, Original javax.servlet.HttpSession von AtmosphereResource Objekt zu verwenden. (V. 9.3.7)

Wenn ich meine Anwendung auf Jetty bereitstellen, erhalte ich folgende Fehler:

16:45:16.535 [Scanner-1] ERROR org.atmosphere.util.IOUtils -

    at java.util.TimerThread.run(Timer.java:505) [na:1.8.0_74] 

Wenn ich native API zwingen, den Vorrang mit dem folgenden Code zu nehmen

params.put(ApplicationConfig.WEBSOCKET_SUPPRESS_JSR356, "true"); 

dann funktioniert alles gut.

Hier ist mein Deployment Descriptor:

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns="http://java.sun.com/xml/ns/javaee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
     version="3.0"> 

    <listener> 
     <listener-class>com.sample.guice.GuiceContextListener</listener-class> 
    </listener> 

    <filter> 
     <filter-name>guiceFilter</filter-name> 
     <filter-class>com.google.inject.servlet.GuiceFilter</filter-class> 
    </filter> 

    <filter-mapping> 
     <filter-name>guiceFilter</filter-name> 
     <url-pattern>/*</url-pattern> 
    </filter-mapping> 
</web-app> 

Das Modul verwendet, um alle Bindungen zu bieten:

public class ServerModule extends AbstractModule 
{ 
    @Override 
    protected void configure() 
    { 
     install(new ServletModule() { 
      @Override 
      protected void configureServlets() 
      { 
       Map<String, String> params = new HashMap<>(); 
       // params.put(ApplicationConfig.WEBSOCKET_SUPPRESS_JSR356, "true"); 
       serve("/atmosphere").with(AtmosphereGuiceServlet.class, params); 
      } 
     }); 
    } 
} 

ich die Klasse ausgelassen mit @ManagedService kommentiert und einen anderen Code, da es keine Probleme gibt. Wie gesagt, alles funktioniert gut mit der nativen Websocket-API.

Answer 1

Sie können einfach ApplicationConfig.JSR356_MAPPING_PATH initParameter hinzufügen und es versuchen.

Wenn es nicht funktioniert, können Sie Atmosphärenrahmen explizit initialisieren und init param ApplicationConfig.JSR356_MAPPING_PATH als gültiges Schlüsselwertpaar angeben.

Zur Initialisierung können Sie org.atmosphere.cpr.ContainerInitializer sehen und zum Hinzufügen des Pfades beim Initalizing der Atmosphäre Rahmen

final AtmosphereFramework Rahmen = AtmosphereFrameworkInitializer.newAtmosphereFramework (c, false, true); // Hack zu machen jsr356 funktioniert. Ziemlich hässlich. DefaultAsyncSupportResolver resolver = neuer DefaultAsyncSupportResolver (framework.getAtmosphereConfig());

Framework.getAtmosphereConfig(). AddInitParam (ApplicationConfig.JSR356_MAPPING_PATH, passenderDevletPath);
