先建工程

下一步，輸入坐標

下一步，輸入工程名

先看一下最終目錄

修改pom文件

Send類：

package com.example.demo;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

public class Send {

    private static final String QUEUE_NAME = "hello";

    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory factory = new ConnectionFactory();    // 連接工廠
        factory.setHost("localhost");
        Connection connection = factory.newConnection();        // 獲取連接
        Channel channel = connection.createChannel();

        channel.queueDeclare(QUEUE_NAME, false, false, false, null);    // 聲明隊列，只有他不存在的時候創建
        String msg = "Hello World!";
        channel.basicPublish("", QUEUE_NAME, null, msg.getBytes());
        System.out.println("Sending:" + msg);
        channel.close();
        connection.close();

    }

}

Receive類：

package com.example.demo;

import com.rabbitmq.client.*;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

public class Receive {

    private static final String QUEUE_NAME = "hello";

    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory factory = new ConnectionFactory();    // 連接工廠
        factory.setHost("localhost");
        Connection connection = factory.newConnection();        // 獲取連接
        Channel channel = connection.createChannel();

        channel.queueDeclare(QUEUE_NAME, false, false, false, null);    // 聲明隊列，只有他不存在的時候創建

        Consumer consumer = new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                String recv = new String(body, "UTF-8");
                System.out.println("Receive:" + recv);
            }
        };

        channel.basicConsume(QUEUE_NAME, true, consumer);
    }
}

先啟動Send，查看控制臺

再啟動Receive
