websocket如何注入service方法

Question

@ServerEndpoint(value = "/websocket")
public class WebSocket {

private Logger logger = Logger.getLogger(this.getClass().getName());

static Map<String,Session> sessionMap = new HashMap<String,Session>();

@OnOpen
public void onOpen(Session session) {
    sessionMap.put(session.getId(), session);
}

@OnMessage
public void onMessage(String unscrambledWord, Session session) {
    broadcastAll("message",unscrambledWord);
}

/**
 * @param message
 */
public static void broadcastAll(String type,String message){
    Set<Map.Entry<String,Session>> set = sessionMap.entrySet();
    for(Map.Entry<String,Session> i: set){
        try {
            i.getValue().getBasicRemote().sendText("{type:'"+type+"',text:'"+message+"'}");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

@OnClose
public void onClose(Session session, CloseReason closeReason) {
    sessionMap.remove(session.getId());
    logger.info(String.format("Session %s closed because of %s", session.getId(), closeReason));
}

@OnError
public void error(Session session, Throwable throwable){
    sessionMap.remove(session.getId());
    System.err.println("session "+session.getId()+" error:"+throwable);
}

}
