Question

我正计划编写一个流媒体类，我想为其尝试打开websocket连接，但无法使我的websocket连接正常工作。这样做的目的是使TDAmeritrade api流数据起作用。

试图使用javax.websocket-api-1.1.jar和tyrus-standalone-client-1.9

我应该使用其他的罐子吗？

package socketProg;
import java.net.URI;
import javax.websocket.*;
@ClientEndpoint
public class WSClient  {
    private static Object waitLock = new Object();
@OnMessage
    public void onMessage(String message) {
//the new USD rate arrives from the websocket server side.
       System.out.println("Received msg: "+message);        
    }
 private static void  wait4TerminateSignal()
 {
  synchronized(waitLock)
  {try {
    waitLock.wait();
   } catch (InterruptedException e) {    
   }}}
public static void main(String[] args) {
WebSocketContainer container=null;//
     Session session=null;
  try{
   //Tyrus is plugged via ServiceLoader API. See notes above
   container = ContainerProvider.getWebSocketContainer(); 
//WS1 is the context-root of my web.app 
//ratesrv is the  path given in the ServerEndPoint annotation on server implementation
session=container.connectToServer(WSClient.class, URI.create("ws://localhost:8080/WS1/ratesrv")); 
   wait4TerminateSignal();
  } catch (Exception e) {
   e.printStackTrace();
  }
  finally{
   if(session!=null){
    try {
 session.close();
    } catch (Exception e) {     
     e.printStackTrace();
    }

我希望建立连接，但出现以下错误

对于javax.websocket-api jar-出现此错误：

java.lang.RuntimeException: Could not find an implementation class. at javax.websocket.ContainerProvider.getWebSocketContainer(ContainerProvider.java: 73) at socketProg.WSClient.main(WSClient.java:24)

对于tyrus-standalone-client-1.9出现此错误：
