Rabbitmq，转换发送和接收消息

Question

我已经看到在Spring AMQP中我们使用了folliwing结构：

String response = (String) template.convertSendAndReceive("query-example-2",message);

要获得回复，用户是否接收了消息。如何在没有spring框架的java中使用这个结构。我的制片人课程

public class EmitLogDirect {

  private static final String EXCHANGE_NAME = "direct_logs";

  public static void main(String[] argv) throws Exception {

    ConnectionFactory factory = new ConnectionFactory();

      factory.setHost("localhost");

      System.out.println("host: "+factory.getVirtualHost());
    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    channel.exchangeDeclare(EXCHANGE_NAME, BuiltinExchangeType.DIRECT);

    String severity = getSeverity(argv);
    String message = getMessage(argv);

    channel.basicPublish(EXCHANGE_NAME, severity, null, message.getBytes("UTF-8"));
    System.out.println(" [x] Sent '" + severity + "':'" + message + "'");

    channel.close();
    connection.close();
  }
