Jboss 7.1.1下的PrimePush

Question

我正在开发一个使用PrimePush技术的反例应用程序。我使用的是Jboss 7.1.1下的Promefaces 5.0和Atmosphere 2.1.6

我发现使用Primefaces 3.4.2和atmosphere 1.0.8推送是可行的。但是我必须使用primefaces 5.0

所以我使用的是官方的Primefaces计数器示例

@ManagedBean
@ApplicationScoped
public class GlobalCounterView implements Serializable{

    private volatile int count;

    public int getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }

    public void increment() {
        count++;

        EventBus eventBus = EventBusFactory.getDefault().eventBus();
        eventBus.publish("/counter", String.valueOf(count));
    }
}

这是我的web.xml

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet>
    <servlet-name>Push Servlet</servlet-name>
    <servlet-class>org.primefaces.push.PushServlet</servlet-class>
    <init-param>
        <param-name>org.atmosphere.useWebSocket</param-name>
        <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>org.atmosphere.cpr.sessionSupport</param-name>
        <param-value>true</param-value>
    </init-param>
    <init-param>
        <param-name>org.atmosphere.useNative</param-name>
        <param-value>true</param-value>
    </init-param>
    <init-param>
        <param-name>org.atmosphere.cpr.broadcasterCacheClass</param-name>
        <param-value>org.atmosphere.cache.HeaderBroadcasterCache</param-value>
    </init-param>
    <init-param>
        <param-name>org.atmosphere.cpr.broadcastFilterClasses</param-name>
        <param-value>org.atmosphere.client.TrackMessageSizeFilter</param-value>
    </init-param>
    <init-param>
        <param-name>org.atmosphere.resumeOnBroadcast</param-name>
        <param-value>true</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
</servlet>
<servlet-mapping>
    <servlet-name>Push Servlet</servlet-name>
    <url-pattern>/primepush/*</url-pattern>
</servlet-mapping>

然后，我将Jboss配置为使用高级IO

<subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="true">

但是，当我部署应用程序并单击count按钮时，我得到以下错误

10:31:50,019 INFO  [org.atmosphere.cpr.AtmosphereFramework] (MSC service thread 1-8) Installed     AtmosphereInterceptor @PushEndpoint Interceptor with priority AFTER_DEFAULT

there is no context.xml under WEB-INF Is the NIO or APR Connector enabled?

我可以在此配置中使用PrimePush吗？如果不能，在jboss 7.1.1中有没有其他方法可以将数据推送到网页？

我使用以下版本和配置运行此程序：

Primefaces 5.0、JBoss 7.1、Atmosphere 2.1.3

web.xml

<servlet>
    <servlet-name>PrimePushServlet</servlet-name>
    <servlet-class>org.primefaces.push.PushServlet</servlet-class>
    <async-supported>true</async-supported>
    <init-param>
        <param-name>org.atmosphere.cpr.broadcasterCacheClass</param-name>
        <param-value>org.atmosphere.cache.UUIDBroadcasterCache</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>PrimePushServlet</servlet-name>
    <url-pattern>/primepush/*</url-pattern>
</servlet-mapping>

日志文件状态

但它确实有效..。如果有人真的设法摆脱了这些消息，我将很高兴知道如何:)

你是否确保你的JBoss是从使用本机库开始的？要在日志中进行验证，请尝试查找字符串org.apache.coyote.http11.Http11AprProtocol而不是org.apache.coyote.http11.Http11Protocol。如果不是这样，请参阅how to fix JBoss configuration here。

此外，您还需要使用atmosphere-runtime-native库，而不是纯atmosphere-runtime。

希望能对你有所帮助。
