基于注解的 Java WebSocket 服务如何启动？

Question

Google 了一圈，大部分只说了如何创建，并未提及如何启动。请问，这个 ws 服务如何启动？代码如下：@ServerEndpoint(value = "/chat-room-channel")public class ChatRoomChannel {  Logger logger = LoggerFactory.getLogger(ChatRoomChannel.class);  public static final Set<Session> SESSIONS = Collections.synchronizedSet(new HashSet<Session>());  public static void notifyAll(String message) {    synchronized (SESSIONS) {      final Iterator<Session> i = SESSIONS.iterator();      while (i.hasNext()) {        final Session session = i.next();        if (session.isOpen()) {          session.getAsyncRemote().sendText(message);        }      }    }  }  @OnOpen  public void onConnect(final Session session){    SESSIONS.add(session);    HashMap<String, Object> msgMap = new HashMap<String, Object>();    msgMap.put(Commom.TYPE, Commom.ONLINE);    msgMap.put(Commom.MESSAGE, SESSIONS.size());    String messgae = new JSONObject(msgMap).toString();    logger.debug(messgae);    notifyAll(messgae);  }}
