使用spring集成的Tcp客户端无法从服务器获得响应

时间：2017-06-03 20:58:09

标签： java spring spring-boot spring-integration tcpclient

我使用cusctom serialzer和deserialzer创建了一个带有SI的Tcpclient，它将字符串“kksingh”的序列化字节数组发送到服务器，并接收响应作为字节数组，反序列化回到字符串。我能够向服务器发送请求，但是我无法得到回应。 但它在日志中显示来自池的thread1已收到消息但我的主线程无法获取它。 我的TcpClientclass

我更新的custommapper类

    public class CustomMapper extends TcpMessageMapper
{

    @Override
    protected Map<String, ?> supplyCustomHeaders(TcpConnection connection)
    {
        Map<String, String> temp = new HashMap<>();
        temp.put("correlationId", connection.getConnectionId());
        System.out.println("correlationId--" + connection.getConnectionId());

        return temp;
    }

}

现在我的更新日志正在显示

我的服务器类很简单

echoServer = new ServerSocket(9999);
 clientSocket = echoServer.accept();
        System.out.println("client connection established..");
        is = new DataInputStream(clientSocket.getInputStream());
        os = new PrintStream(clientSocket.getOutputStream());
        // As long as we receive data, echo that data back to the client.
        String tempString = "kksingh";
        byte[] tempStringByte = tempString.getBytes();
        byte[] temp = new byte[tempString.getBytes().length];
        while (true)
        {
            is.read(temp);
            System.out.println(new String(temp) + "--received byte is--- ");
            System.out.println("sending value");
            os.write(tempStringByte);
            break;
        }

请告诉我如何让主线程总是等待来自服务器的响应使用自定义序列化器和desrialzer PS：我是春季整合新手。

1 个答案:

答案 0 :(得分：0)

你的

final String msg = gateway.send("kksingh");

调用已经是同步方法调用。并且线程将不会进入下一个操作，直到返回此操作。这就是Java和任何其他语言的工作方式。这与潜在的呼叫如何运作无关。

是的，您在日志中看到的意味着在侦听线程中收到了回复，但主线程被阻止，因为我们正在等待回复条件。
