尝试正常关闭时，控制台中的输出为：
18:36:08,342 INFO [org.jboss.as.server] (management-handler-thread - 5) WFLYSRV0211: Suspending server
18:36:08,345 INFO [org.jboss.as.server] (Thread-2) WFLYSRV0220: Server shutdown has been requested.

服务器的状态在此之后保持停止状态，而不是停止。 大约5分钟后，eclipse对话框无法在服务器中停止服务器：
19:29:11,600 WARN [com.arjuna.ats.arjuna] (Transaction Reaper) ARJUNA012117: TransactionReaper::check timeout for TX 0:ffffc0a80104:6ad8fb66:5637aa44:c in state RUN

之后，即使我在尝试访问webapp的页面时获得404，状态也会开始。我不确定错误中的含义是什么：Unregistered web context: /csbasement。 csbasement是webapp的名称。另外，当使用clean时，webapp状态保持启动状态，所以我要停止服务器，清理并重新启动它。
启动时出现此错误但正常启动：
19:17:16,344 ERROR [org.jboss.remoting.remote.connection] (XNIO-1 I/O-2) JBREM000200: Remote connection failed: java.io.IOException: An established connection was aborted by the software in your host machine

}
我会在jsf页面上得到这样的推文：value="#{launchBackgroundTasks.msgList}"，这对于glassfish“正在工作”。
这不是异步启动（java @Asynchronous Methods: not running async）
@Eager
@Named
@ApplicationScoped
public class TwitterLatestTweets {
private LinkedBlockingQueue<Tweet> tweets;
@PostConstruct
public void init() {
makeLatestsTweets();
}
//notation not taken into account
@Asynchronous
public void makeLatestsTweets() {
// hosebirdClient is twitter streaming so I'm getting tweets as long as the app is alive.
while (!hosebirdClient.isDone()) {
try {
String msg = msgQueue.take();
Tweet tweet = format(msg);
tweets.put(tweet);
}
} catch (InterruptedException e) {
hosebirdClient.stop();
e.printStackTrace();
}
}
}
答案 0 :(得分：0)
我很顽固地使用@Asynchronous，因为我想要管理我的线程，但我不能让它像这样工作。我无法找到中断异步方法的线程的方法。所以我回到正常的线程，完成我想要的工作。
@Eager
@Named
@ApplicationScoped
public class LaunchBackgroundTasks {
@EJB
TopStreamInterface topStream;
Thread twitterThread;
List<Tweet> tweets;
@PostConstruct
public void init() {
tweets = new LinkedList<Tweet>();
twitterThread = new Thread(new TwitterLatestTweets(this));
twitterThread.start();
}
@PreDestroy
public void destroyTwitterClient() {
twitterThread.interrupt();
}
}
和线程：
public class TwitterLatestTweets implements Runnable {
private final static String BUNDLE_BASENAME = "configuration.twitter";
private final static String CONSUMER_KEY = ResourceBundle.getBundle(
BUNDLE_BASENAME).getString("consumerKey");
private final static String CONSUMER_SECRET = ResourceBundle.getBundle(
BUNDLE_BASENAME).getString("consumerSecret");
private final static String TOKEN = ResourceBundle.getBundle(
BUNDLE_BASENAME).getString("token");
private final static String SECRET = ResourceBundle.getBundle(
BUNDLE_BASENAME).getString("secret");
// private LinkedBlockingQueue<Tweet> msgList;
private List<Long> userIds;
private int tweetListSize = 10;
TwitterLatestTweets(LaunchBackgroundTasks caller) {
this.caller = caller;
}
@Override
public void run() {
makeLatestsTweets();
}
public void makeLatestsTweets() {
BlockingQueue<String> msgQueue = new LinkedBlockingQueue<String>(100);
StatusesFilterEndpoint hosebirdEndpoint = new StatusesFilterEndpoint();
userIds = addFollowings();
hosebirdEndpoint.followings(userIds);
Authentication hosebirdAuth = new OAuth1(CONSUMER_KEY, CONSUMER_SECRET,
TOKEN, SECRET);
Client client = new ClientBuilder().name("test")
.hosts(Constants.STREAM_HOST).endpoint(hosebirdEndpoint)
.authentication(hosebirdAuth)
.processor(new StringDelimitedProcessor(msgQueue)).build();
client.connect();
while (!client.isDone()) {
try {
String msg = msgQueue.take();
//...
caller.setTweets(aTweetLinkedList);
}
} catch (InterruptedException e) {
System.out.println("twitter interrupted");
client.stop();
e.printStackTrace();
}
}
}
}
