Jersey 气氛：如何取消订阅广播

简单的问题是，如何从JavaAPI取消订阅广播？我在API中找不到任何突出的东西，在Google上也找不到任何突出的东西

堆栈：Java7、Atmosphere 2.2.3、Atmosphere Jersey 2.2.3、Servlet 3、Tomcat7

我就是这样订阅的：

@Path("subscription")
public class CurrencyPairSubscription {

    @GET
    @Suspend
    @Path("{pair}")
    public Broadcastable subscribeToQuote(@PathParam("pair") String pair,
            @Context final BroadcasterFactory broadcasterFactory) {

        return new Broadcastable(broadcasterFactory.lookup(pair, true));
    }
}

public class BroadcasterServlet extends HttpServlet {

    private static final long serialVersionUID = 1L;

    @Override
    public void init() {

        System.out.println("Broadcast Servlet init");
        AtmosphereFramework framework = (AtmosphereFramework) getServletContext()
                .getAttribute("AtmosphereServlet");
        MetaBroadcaster metaBroadcaster = framework.metaBroadcaster();


        metaBroadcaster.scheduleTo(RandomQuoteGenerator.generate()
                .getIdentifier(), RandomQuoteGenerator.retrieveLastQuote(), 15,
                TimeUnit.MILLISECONDS);
    }
}

这就是我的广播方式：

@Path("subscription")
public class CurrencyPairSubscription {

    @GET
    @Suspend
    @Path("{pair}")
    public Broadcastable subscribeToQuote(@PathParam("pair") String pair,
            @Context final BroadcasterFactory broadcasterFactory) {

        return new Broadcastable(broadcasterFactory.lookup(pair, true));
    }
}

public class BroadcasterServlet extends HttpServlet {

    private static final long serialVersionUID = 1L;

    @Override
    public void init() {

        System.out.println("Broadcast Servlet init");
        AtmosphereFramework framework = (AtmosphereFramework) getServletContext()
                .getAttribute("AtmosphereServlet");
        MetaBroadcaster metaBroadcaster = framework.metaBroadcaster();


        metaBroadcaster.scheduleTo(RandomQuoteGenerator.generate()
                .getIdentifier(), RandomQuoteGenerator.retrieveLastQuote(), 15,
                TimeUnit.MILLISECONDS);
    }
}

在客户端js/jquery上，您可以调用

unsubscribe

方法来关闭连接

socket.unsubscribe(request);

在服务器端，您可以使用AtmosphereResource方法取消订阅用户。注意，您可以尝试插入

AtmosphereSourceFactory

以访问所有AtmosphereSource连接

@Inject
private AtmosphereResourceFactory resourceFactory;

然后找到唯一的UUID并关闭连接

resourceFactory.find(userUUID).close();

看起来我不需要在服务器端取消订阅，只需让客户端处理即可。是这样吗？是的，通常由客户端取消订阅。
