无法连接到服务器java_SignalR java无法连接到服务器

我可以连接Web客户端(javascript)和Windows客户端(C#)但我的java客户端有问题.(https://github.com/SignalR/java-client)

到目前为止,这是我的代码:

package javaapplication2;

import java.io.IOException;

import java.util.concurrent.ExecutionException;

import java.util.concurrent.TimeoutException;

import microsoft.aspnet.signalr.client.SignalRFuture;

import microsoft.aspnet.signalr.client.hubs.HubConnection;

import microsoft.aspnet.signalr.client.hubs.HubProxy;

public class JavaApplication2 {

public static void main(String[] args) throws IOException, InterruptedException, ExecutionException, TimeoutException

{

String ServerURI = "http://localhost:8080/signalr";

HubConnection Connection = new HubConnection(ServerURI);

HubProxy HubProxy = Connection.createHubProxy("MyHub");

HubProxy.on("AddMessage", () -> { System.out.println("Some message"); });

Connection.error(new ErrorCallback() {

@Override

public void onError(Throwable error) {

error.printStackTrace(); //<==SocketException

}

});

SignalRFuture con =Connection.start();

con.get();

}

}

更新

当我运行它时,我得到一个"ExecutionException:java.net.SocketException:Connection reset"

Exception in thread "main" java.util.concurrent.ExecutionException: java.net.SocketException: Connection reset

- 如果我将"localhost"更改为不存在的东西(例如locahostX),我会得到一个java.net.UnknownHostException

- 如果将"localhost"更改为我的IP我没有事件获得异常...

- 所有其他应用程序都适用于(localhost或IP)

起初我以为这是一个防火墙问题,但不是......

显然我错过了什么......有什么想法吗？

谢谢
