Question

我试图在weblogic 11G（10.3.6）中使用带有弹簧的Atmosphere，所以我只提供了servlet 2.5。

我尝试按照http://async-io.org/tutorial.html和https://github.com/Atmosphere/atmosphere/wiki/Configuring-Atmosphere-as-a-Spring-Bean

中的氛围教程进行操作

我的相关代码

的pom.xml

<dependency>
    <groupId>org.atmosphere</groupId>
    <artifactId>atmosphere-runtime</artifactId>
    <version>2.4.2</version>
</dependency>

<dependency>
    <groupId>org.atmosphere</groupId>
    <artifactId>atmosphere-spring</artifactId>
    <version>2.4.2</version>
</dependency>

servlet.xml中

<bean id="framework" class="org.atmosphere.cpr.AtmosphereFramework">
    <constructor-arg index="0" value="false"/>
    <constructor-arg index="1" value="false"/>
</bean>

<bean class="org.atmosphere.spring.bean.AtmosphereSpringContext">
    <property name="config">
        <map>
            <entry key="org.atmosphere.cpr.broadcasterClass" value="org.atmosphere.cpr.DefaultBroadcaster" />
            <entry key="org.atmosphere.cpr.AtmosphereInterceptor" value="org.atmosphere.interceptor.AtmosphereResourceLifecycleInterceptor, org.atmosphere.client.TrackMessageSizeInterceptor, org.atmosphere.interceptor.HeartbeatInterceptor, org.atmosphere.interceptor.SuspendTrackerInterceptor, org.atmosphere.config.managed.AnnotationServiceInterceptor"/>
            <entry key="org.atmosphere.cpr.broadcasterLifeCyclePolicy"
                    value="IDLE_DESTROY" />
        </map>
    </property>
</bean>

的web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/root-context.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
    <servlet-name>callcenter-ui</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>callcenter-ui</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<servlet>

    <servlet-name>AtmosphereServlet</servlet-name>
    <servlet-class>org.atmosphere.spring.bean.AtmosphereSpringServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>AtmosphereServlet</servlet-name>
    <url-pattern>/chat/*</url-pattern>
</servlet-mapping>

Chat.java

@ManagedService(path = "/test", atmosphereConfig = MAX_INACTIVE + "=120000")
public class Chat {
    private final Logger logger = LoggerFactory.getLogger(Chat.class);

    @Heartbeat
    public void onHeartbeat(final AtmosphereResourceEvent event) {
        logger.trace("Heartbeat send by {}", event.getResource());
    }

    /**
     * Invoked when the connection has been fully established and suspended, that is, ready for receiving messages.
     *
     */
    @Ready
    public void onReady(/* In you don't want injection AtmosphereResource r */) {

    }

    /**
     * Invoked when the client disconnects or when the underlying connection is closed unexpectedly.
     *
     */
    @Disconnect
    public void onDisconnect(/** If you don't want to use injection AtmosphereResourceEvent event*/) {

    }

    /**
     * Simple annotated class that demonstrate how {@link org.atmosphere.config.managed.Encoder} and {@link org.atmosphere.config.managed.Decoder
     * can be used.
     *
     * @param message an instance of {@link Response}
     * @return
     * @throws IOException
     */
    @Message(encoders = {MessageEncoderDecoder.class}, decoders = {MessageEncoderDecoder.class})
    public Response onMessage(Response message) throws IOException {
        logger.info("{} just sent {}", message.getAuthor(), message.getMessage());
        return message;
    }

}

当我尝试运行该示例时，它返回

指出我做错了什么？我已经尝试过使用weblogic servlet的例子，它可以工作。

EDIT1 使用weblogic servelet时，我使用

<dependency>
    <groupId>org.atmosphere</groupId>
    <artifactId>atmosphere-weblogic</artifactId>
    <version>2.4.2</version>
</dependency>

而不是spring依赖。我在servlet.xml中没有关于氛围的配置，web.xml看起来像这样

<servlet>
    <servlet-name>callcenter-ui</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>callcenter-ui</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<servlet>
    <description>AtmosphereServlet</description>
    <servlet-name>AtmosphereServlet</servlet-name>
    <servlet-class>org.atmosphere.weblogic.AtmosphereWebLogicServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>AtmosphereServlet</servlet-name>
    <url-pattern>/chat/*</url-pattern>
</servlet-mapping>

其余的代码是相同的，在这种情况下它可以工作。

我想要实现的是我有一个MessageListener，我希望在收到消息时访问BroadcasterFactory以向大气广播。根据我对框架bean的理解，我应该能够实现这一点。

在春天将大气层配置为豆类
