如何解决客户端计算机和vps服务器JAVA之间的通信
我知道有很多帖子询问如何在客户端和服务器之间进行通信，但在大多数情况下，这些通常是使用本地主机的人，我必须为项目使用 vps 和几台客户端计算机，不幸的是所有解决方案都给出了在另一篇文章中不起作用，确实客户端似乎无法连接到我的 vps
这是我的客户端代码
public IRCClient() throws IOException {
socket = new Socket(InetAddress.getByAddress(new byte[]{(byte) 185,(byte) 242,(byte) 180,97}),2406);
messages = new LinkedBlockingQueue<Object>();
server = new ConnectionToServer(socket);
Thread messageHandling = new Thread() {
public void run() {
while (true) {
try {
Object message = messages.take();
parse(message);
System.out.println("Message Received: " + message);
} catch (InterruptedException e) {
}
}
}
};
messageHandling.setDaemon(true);
messageHandling.start();
}
private void parse(Object message) {
String msg = String.valueOf(message);
if (msg.contains("-")) {
if (msg.contains("key")) {
key = msg.split("-")[1];
} else if (msg.contains("name")) {
name = msg.split("-")[1];
} else if (msg.contains("world")) {
world = msg.split("-")[1];
} else if (msg.contains("server")) {
serverName = msg.split("-")[1];
} else if (msg.contains("x")) {
x = Integer.parseInt(msg.split("-")[1]);
} else if (msg.contains("y")) {
y = Integer.parseInt(msg.split("-")[1]);
} else if (msg.contains("z")) {
z = Integer.parseInt(msg.split("-")[1]);
} else if (msg.contains("isEntity")) {
entity = msg.split("-")[1].equalsIgnoreCase("true");
} else if (msg.contains("ticks")) {
lTicks = Integer.parseInt(msg.split("-")[1]);
} else if (msg.contains("end")) {
if (key.equalsIgnoreCase(MultiPingMod.getKey()) && !name.equalsIgnoreCase(Minecraft.getMinecraft().thePlayer.getName())) {
MultiPing m = new MultiPing(name,world,serverName,x,y,z,entity);
MultiPingMod.setTime(lTicks);
m.render = true;
if (MultiPingMod.render.getToRender().containsKey(name)) {
MultiPingMod.render.getToRender().get(name).render = false;
MultiPingMod.render.getToRender().remove(name);
}
MultiPingMod.render.addToRender(m);
}
}
}
}
public void send(Object obj) {
server.write(obj);
}
private class ConnectionToServer {
ObjectInputStream in;
ObjectOutputStream out;
Socket socket;
ConnectionToServer(Socket socket) throws IOException {
this.socket = socket;
in = new ObjectInputStream(socket.getInputStream());
out = new ObjectOutputStream(socket.getOutputStream());
Thread read = new Thread() {
public void run() {
while (true) {
try {
Object obj = in.readObject();
messages.put(obj);
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
};
read.setDaemon(true);
read.start();
}
private void write(Object obj) {
try {
out.writeObject(obj);
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
我从这个论坛的某个地方得到了这个代码，因为经过多次尝试后，没有任何效果 这里的服务器代码相同：
public ServerListener() {
debug("Creating the server");
clientList = new ArrayList<ConnectionToClient>();
messages = new LinkedBlockingQueue<Object>();
debug("Client list is created");
try {
serverSocket = new ServerSocket(2406);
debug("opening the port 2406");
} catch (IOException e) {
e.printStackTrace();
debug(e.getMessage());
}
debug("creating the accept thread");
Thread accept = new Thread() {
public void run() {
debug("thread created");
while (true) {
try {
Socket s = serverSocket.accept();
if(s!=null) {
debug("new client joined");
clientList.add(new ConnectionToClient(s));
debug("new client was accepted ["+ s.getInetAddress() + "/" + s.getPort()+"]");
}
} catch (IOException e) {
e.printStackTrace();
debug(e.getMessage());
}
}
}
};
accept.setDaemon(true);
accept.start();
Thread messageHandling = new Thread() {
public void run() {
while (true) {
try {
Object message = messages.take();
debug("we parse the ping");
parse(message);
System.out.println("Message Received: " + message);
} catch (InterruptedException e) {
}
}
}
};
messageHandling.setDaemon(true);
messageHandling.start();
}
private void parse(Object message) {
String msg = String.valueOf(message);
if(msg.contains("-")) {
if(msg.contains("key")) {
debug("key detected");
key = msg.split("-")[1];
} else if(msg.contains("name")) {
debug("name detected");
name = msg.split("-")[1];
} else if(msg.contains("world")) {
debug("worldname detected");
world = msg.split("-")[1];
} else if(msg.contains("server")) {
debug("servername detected");
server = msg.split("-")[1];
} else if(msg.contains("x")) {
debug("x detected");
x = Integer.parseInt(msg.split("-")[1]);
} else if(msg.contains("y")) {
debug("y detected");
y = Integer.parseInt(msg.split("-")[1]);
} else if(msg.contains("z")) {
debug("z detected");
z = Integer.parseInt(msg.split("-")[1]);
} else if(msg.contains("isEntity")) {
debug("entity detected");
entity = msg.split("-")[1].equalsIgnoreCase("true");
} else if(msg.contains("ticks")) {
debug("ticks detected");
lTicks = Integer.parseInt(msg.split("-")[1]);
} else if(msg.contains("end")) {
debug("we got everything detected");
toSend = new IrcMPING(key,name,server,entity,lTicks);
for(String str : toSend.getArgs()) {
sendToAll(str);
}
toSend=null;
}
}
}
public void sendToOne(int index,Object message) throws IndexOutOfBoundsException {
clientList.get(index).write(message);
}
public void sendToAll(Object message) {
for (ConnectionToClient client : clientList) {
debug("sending the ping to " + client.socket.getInetAddress());
client.write(message);
}
}
public void debug(String str) {
System.out.println("SOROS DEBUG [MULTIPING] : " + str) ;
}
private class ConnectionToClient {
ObjectInputStream in;
ObjectOutputStream out;
Socket socket;
ConnectionToClient(Socket socket) throws IOException {
this.socket = socket;
in = new ObjectInputStream(socket.getInputStream());
out = new ObjectOutputStream(socket.getOutputStream());
Thread read = new Thread() {
public void run() {
while (true) {
try {
Object obj = in.readObject();
messages.put(obj);
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
};
read.setDaemon(true); // terminate when main ends
read.start();
}
public void write(Object obj) {
try {
out.writeObject(obj);
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
我使用 java jar 命令从 vps（基于 debian）运行 jar，但无事可做，我只在终端上得到这个

我该怎么做才能完成这项工作？除了套接字，还有其他方法可以让两个 jar 从远程计算机/服务器进行通信吗？感谢您阅读我并感谢您尝试帮助我
