Question

我正在尝试使用Spring集成实现tcp-ip客户端。我的服务器是普通的Java套接字应用程序。我正在尝试使用Spring Integration Client与服务器进行通信。我能够将数据发送到服务器，但是当我从套接字服务器返回响应时，则无法在客户端上获取它并获得套接字关闭异常。我不确定哪里做错了。请帮助我解决问题或提出最佳解决方案（我们需要在Spring集成中开发客户端）。

Java套接字服务器代码：

try {
      SSLServerSocketFactory factory=(SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
      sslserversocket=(SSLServerSocket) factory.createServerSocket(1234);


      while (true) {
        try {
          System.out.println("Waiting for client on port " + sslserversocket.getLocalPort() + "...");
          SSLSocket server = (SSLSocket) sslserversocket.accept();
          System.out.println("Just connected to " + server.getRemoteSocketAddress());

          Scanner sc = new Scanner(server.getInputStream());

          String op = sc.next();

          System.out.println("Input data : " + op);

          DataOutputStream out = new DataOutputStream(server.getOutputStream());
          out.writeBytes(op + "===");
          //out.writeUTF("returning " + op);
          out.flush();
          //server.close();
        } catch (SocketTimeoutException s) {
          System.out.println("Socket timed out!");
          break;
        } catch (IOException e) {
          e.printStackTrace();
          break;
        }
      }

输出：
