Java RabbitMQ发送对象

你好，我是RabbitMQ新手，我尝试在两个应用程序之间发送一个对象，但它不起作用。然后我发现我需要序列化和反序列化对象，但它仍然不起作用。当我发送一个字符串时没有问题，但是对于它不工作的对象，应用程序之间突然没有连接，我不确定我做错了什么

这是Sender.java:

import org.apache.commons.lang3.SerializationUtils;
import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;

import java.io.ByteArrayOutputStream;
import java.io.ObjectOutput;
import java.io.ObjectOutputStream;

public class App {

private final static String QUEUE_NAME = "12345";

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

    ConnectionFactory factory = new ConnectionFactory();

    factory.setHost("somehost"); 
    factory.setUsername("guest"); 
    // factory.setPassword( "password" ); 
    //factory.setPort( 12345 ); 

    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    channel.queueDeclare(QUEUE_NAME, false, false, false, null);

    Car car = new Car(4, 4, "Mercedes");

    byte[] data = SerializationUtils.serialize(car);

    channel.basicPublish("", QUEUE_NAME, null, data);
    System.out.println(" [x] Sent '" + data + "'");

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

import org.apache.commons.lang3.SerializationUtils;
import com.rabbitmq.client.*;
import java.io.IOException;

public class Recipient {

     private final static String QUEUE_NAME = "12345";

public static void main(String[] argv) throws Exception {
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("Somehost");
    factory.setUsername("guest"); 
    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    channel.queueDeclare(QUEUE_NAME, false, false, false, null);
    System.out.println(" [*] Waiting for messages. To exit press CTRL+C");
    Consumer consumer = new DefaultConsumer(channel) {

        @Override
        public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body)
                throws IOException {

            String message = new String(body, "UTF-8");
            //byte [] data = new byte[];

            Object object =    SerializationUtils.deserialize(message.getBytes());

            System.out.println(" [x] Received '" + object + "'");
         }
      };
    channel.basicConsume(QUEUE_NAME, true, consumer);
     }
    }

这里是Receiver.java:

import org.apache.commons.lang3.SerializationUtils;
import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;

import java.io.ByteArrayOutputStream;
import java.io.ObjectOutput;
import java.io.ObjectOutputStream;

public class App {

private final static String QUEUE_NAME = "12345";

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

    ConnectionFactory factory = new ConnectionFactory();

    factory.setHost("somehost"); 
    factory.setUsername("guest"); 
    // factory.setPassword( "password" ); 
    //factory.setPort( 12345 ); 

    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    channel.queueDeclare(QUEUE_NAME, false, false, false, null);

    Car car = new Car(4, 4, "Mercedes");

    byte[] data = SerializationUtils.serialize(car);

    channel.basicPublish("", QUEUE_NAME, null, data);
    System.out.println(" [x] Sent '" + data + "'");

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

import org.apache.commons.lang3.SerializationUtils;
import com.rabbitmq.client.*;
import java.io.IOException;

public class Recipient {

     private final static String QUEUE_NAME = "12345";

public static void main(String[] argv) throws Exception {
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("Somehost");
    factory.setUsername("guest"); 
    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    channel.queueDeclare(QUEUE_NAME, false, false, false, null);
    System.out.println(" [*] Waiting for messages. To exit press CTRL+C");
    Consumer consumer = new DefaultConsumer(channel) {

        @Override
        public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body)
                throws IOException {

            String message = new String(body, "UTF-8");
            //byte [] data = new byte[];

            Object object =    SerializationUtils.deserialize(message.getBytes());

            System.out.println(" [x] Received '" + object + "'");
         }
      };
    channel.basicConsume(QUEUE_NAME, true, consumer);
     }
    }

只需直接从

主体

变量反序列化即可

反序列化是什么意思，应用程序之间没有连接？你怎么查的？你在看管理屏幕吗？如果您不检查它，我建议在handleDelivery方法的顶部添加System.out.println，看看它是否到达allanyone，这是否有帮助？应用程序之间没有连接是什么意思？你怎么查的？你在看管理屏幕吗？如果您不检查它，我建议在handleDelivery方法的顶部添加一个System.out.println，看看它是否到达allanyone，这是否有帮助？
