大气是无法配置JSR-356

我创建了Java Web应用程序，并试图强制使用JSR-356的气氛，因为，据我所知，它是唯一的方法使用原始javax.servlet.HttpSession从AtmosphereResource对象。 （诉9.3.7）大气是无法配置JSR-356

当我部署我的应用程序到码头，我得到以下错误：

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

如果我强迫原生API采取优先用下面的代码

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

然后一切正常。

这里是我的部署描述符：

<?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>

用于提供所有绑定的模块：

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); 
      } 
     }); 
    } 
}

我省略与@ManagedService注解类和一些其他的代码，因为不存在任何问题。正如我所说的，一切工作正常与本地websocket API。

我建议在JSR356 websocket上使用jetty native websocket API。 –

+0

@JoakimErdfelt似乎它的本地API不提供握手之前可用的'javax.servlet.session.HttpSession'，所以我必须使用JSR-356 ... –

+1

访问'HttpSession'对于本地API vs JSR356。你有2种方法。 （1）提供您自己的'WebSocketCreator'并根据您的升级过程做任何事情，包括直接使用HttpSession并推入您的websocket类。 （2）使用'api.Session＃getSession（）'随时访问'HttpSession'（在'HttpSession'到期之前） –

您可以添加ApplicationConfig.JSR356_MAPPING_PATH initParameter并尝试一下。

如果不起作用，可能是您可以显式初始化氛围框架并指定init参数 ApplicationConfig.JSR356_MAPPING_PATH作为有效的键值对。

有关初始化，您可以看到org.atmosphere.cpr.ContainerInitializer和添加的路径，而initalizing大气框架

最终AtmosphereFramework框架= AtmosphereFrameworkInitializer.newAtmosphereFramework（C，假的，真正的）; //黑客让jsr356工作。很难看。 DefaultAsyncSupportResolver resolver = new DefaultAsyncSupportResolver（framework.getAtmosphereConfig（））;

framework.getAtmosphereConfig（）。addInitParam（ApplicationConfig.JSR356_MAPPING_PATH，appropriateservletPath）;
