我正在JBoss AS 7.1.2上使用RestEasy实现jax-rs服务，我想使用异步HTTP处理，如下所述：http://docs.jboss.org/resteasy/docs/1.0.0.GA/userguide/html/Asynchronous_HTTP_Request_Processing.html
对于thr AsynchronousResponse，我定义了10秒的超时。当此期限到期时，请求以200 OK和空体响应。我想修改此行为，因此我需要收到有关超时事件的通知。
在我的解决方案中，我想在NotificationManager对象中处理超时事件，该对象暂时保留AsycnhronousResponse。有关详细信息，请参阅以下代码。
到目前为止，我无法弄清楚如何做到这一点。有没有人有更多使用RestEasy异步HTTP处理的经验？
@POST
@Path("/blabla")
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
@Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public void subscribeLongPolling (
final @Suspend(10000) AsynchronousResponse response,
JAXBElement<LongPollingRequestParameters> rqParam,
@Context HttpServletRequest req) throws Exception {
//do some stuff with req
Thread t = new Thread("ThreadSubscribeTo:" + channelID)
{
@Override
public void run() {
//hand over to Notification Manager to return notifications in case some exist
try {
NotificationManager nm = new NotificationManager();
nm.setAsyncResponseObject(response);
logger.info("Response object registered in NotificationManager");
}catch (Exception e){
e.printStackTrace();
}
}
};
t.start();
logger.info("Releasing Thread");
}
public class NotificationManager {
private AsynchronousResponse response;
private NotificationList nList;
public synchronized void setAsyncResponseObject(AsynchronousResponse response) {
this.response = response;
if (nList.getAny().size() > 0) {
logger.info("Stored notification send to web client: " + nList.getAny().get(0).toString());
sendNotification(nList.getAny().remove(0));
}
}
public synchronized void sendNotification(Object message){
if (response != null){
logger.info("Response object found. Send notification immediately: " + message.toString());
Response responseObject = Response.ok(message, MediaType.APPLICATION_XML).build();
response.setResponse(responseObject);
response = null;
}else{
logger.info("Response object not found notification will be stored");
addNotification(message);
}
}
}
