java版RabbitMQ的hello world实现

请确保正确安装了上述环境并使之处于运行状态

一下教程是根据官网教程操作的步骤

建一个Java项目，根据官网提示下载相应jar包：

jar包地址：

amqp-client-4.0.2.jar

slf4j-api-1.7.21.jar

slf4j-simple-1.7.22.jar

代码

send.java

package com.adtec.rabbitmq;

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

public class Send {

private final static String QUEUE_NAME = "hello";

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

channel.queueDeclare(QUEUE_NAME, false, false, false, null);
String message = "Hello World!";
channel.basicPublish("", QUEUE_NAME, null, message.getBytes("UTF-8"));
System.out.println(" [x] Sent '" + message + "'");

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

Recv.java

package com.adtec.rabbitmq;

import com.rabbitmq.client.*;

import java.io.IOException;

public class Recv {

private final static String QUEUE_NAME = "hello";

public static void main(String[] argv) throws Exception {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("localhost");
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");
System.out.println(" [x] Received '" + message + "'");
}
};
channel.basicConsume(QUEUE_NAME, true, consumer);
}
}

运行send.java结果

[x] Sent 'Hello World!'

运行Recv.java结果

[*] Waiting for messages. To exit press CTRL+C
[x] Received 'Hello World!'
