Java TOF 模拟器的 TCP IP 服务器客户端读取线

Question

我尝试编写一个应用程序读取数据并将数据发送到 Reuters TOF 模拟器。

我像这里一样用文件分隔符 (FS ASCII(28)) 向 TOF 服务器发送消息

 包裹 tr.com.calikbank.bnspr.treasury.reutersClient;

import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.Socket;
import java.net.UnknownHostException;

public class Test {

    /**
     * @param args
     */

    public static final String FS = Character.toString((char) 28);
    public static final String US = Character.toString((char) 31);
    public static final String GS = Character.toString((char) 29);

    private static DataInputStream in;
    private static Socket sock;
    private static DataOutputStream out;

    public static void main(String[] args) throws UnknownHostException,
            IOException {
        // TODO Auto-generated method stub

        sock = new Socket("10.90.20.76", 5003);
        sock.setKeepAlive(true);

        in = new DataInputStream(sock.getInputStream());
        out = new DataOutputStream(sock.getOutputStream());

        String message = FS + "333" + US + "AE" + GS + "AAAA#1" + FS;

        out.flush();
        out.writeBytes(message);
        out.flush();

        // BufferedReader reader = new BufferedReader(new
        // InputStreamReader(sock.getInputStream()));
        StringBuilder sb = new StringBuilder();
        String line;

        // line = reader.readLine();
        while ((line = in.readLine()) != null) {
            sb.append(line).append("\n");
            if (line.isEmpty())
                break;

        }
        // line = in.readLine();
        // sb.append(line).append("\n");

        System.out.println("Message received from the server : "
                + sb.toString());

    }

}

但程序卡在 while 循环中，当我停止服务器时 return 整个字符串，但我需要在不停止服务器的情况下获取。有什么问题。

我的决定是 readline 有参考问题 5530xD0xA
