2.rabbitmq 简单生产消费

前言

本文简要介绍如何使用java客户端，连接rabbitmq server。本文开始之前，需要安装好mq服务器，如果不知道怎么安装，可参考rabbitmq安装

使用架构

使用gradle java项目

代码

build.gradle

plugins {
    id 'java'
}

group 'com.nick'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
    compile group: 'com.rabbitmq', name: 'amqp-client', version: '5.2.0'
    compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.25'
    compile group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.25'
    compile group: 'org.projectlombok', name: 'lombok', version: '1.18.0'

}

send 生产者(p)

package com.nick.simpleTest;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.concurrent.TimeoutException;

public class Send {
    private final static String QUEUE_NAME = "hello";
    public  static Logger logger =  LoggerFactory.getLogger(Send.class);

    public static void main(String[] argv)
            throws java.io.IOException, TimeoutException {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("192.168.1.249");
        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());
        logger.info(" [x] Sent '{}'" ,message );

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

}

receive 消费者(c)

package com.nick.simpleTest;

import com.rabbitmq.client.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

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

public class Recv {
    private final static String QUEUE_NAME = "hello";

    public static Logger logger = LoggerFactory.getLogger(Recv.class);

    public static void main(String[] argv)
            throws java.io.IOException, TimeoutException {

        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("192.168.1.249");
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();

        channel.queueDeclare(QUEUE_NAME, false, false, false, null);
        logger.info(" [*] 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");
                logger.info(" [x] Received '" + message + "'");
            }
        };
        channel.basicConsume(QUEUE_NAME, true, consumer);

    }
}

测试

先运行消费者，再运行生产者，效果截图如下：
