WINDOWS下使用RabbitMQ入门详解

最近公司项目需要用到异步业务流程，和几个小伙伴讨论筛选后，最后选定使用RabbitMQ，过程中也是小坑不断，在此总结一下，供大家学习使用：
1，下载ERLANG和RabbitMQ
此处要注意版本选择，版本不同是不能互相兼容的，我选的是RabbitMQ3.7.9和ERLANG：20.0.x：参考RabbitMQ的官网，里面写的很清楚的

2，ERLANG安装
没有技术含量，一路默认安装即可，安装路径：C:\Program Files\erl10.0.1
最后配置一下环境变量：

ERLANG_HOME=C:\Program Files\erl10.0.1
path=%ERLANG_HOME%\bin
进入命令行窗口，看看版本是否正确：erl -version

3，RabbitMQ安装
安装目录：D:\RabbitMQ\rabbitmq_server-3.7.9
安装时，注意安装路径不能有空格，默认安装会有空格，需要去掉空格。
其他地方默认安装即可。

4，RabbitMQ中追加localhost以外机器访问的用户
命令行窗口进入到目录：D:\RabbitMQ\rabbitmq_server-3.7.9\sbin

新建test用户，密码root，授予administrator权限
rabbitmqctl add_user test root
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

5，RabbitMQ启动
命令行窗口进入到目录：D:\RabbitMQ\rabbitmq_server-3.7.9\sbin

rabbitmq-server start

下面以JAVA程序为例子，进行开发
6，新建一个maven工程，加入一下的依赖包

		<!-- rabbitmq相关依赖 -->
		<dependency>
			<groupId>com.rabbitmq</groupId>
			<artifactId>amqp-client</artifactId>
			<version>3.0.4</version>
		</dependency>
		<!-- 序列化相关依赖 -->
		<dependency>
			<groupId>commons-lang</groupId>
			<artifactId>commons-lang</artifactId>
			<version>2.6</version>
		</dependency>

7，新创建一个获取连接的类，工生产者和消费者共用

package rabbitmq;

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

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

public class ConnectionUtils {

    public static Connection getConnection() throws IOException,TimeoutException {
    	//创建连接工厂
        ConnectionFactory factory = new ConnectionFactory();
        // 设置MabbitMQ所在主机ip或者主机名  127.0.0.1即localhost
        factory.setHost("192.168.40.245");
        factory.setPort(5672);
        //factory.setVirtualHost("/vhost_why");
        factory.setUsername("test");
        factory.setPassword("root");
        
        return factory.newConnection();
    }
}

8，新建生产者的类

package rabbitmq;

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

import org.junit.Test;

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

public class Send {

	private static final String QUEUE_NAME = "test_simple_queue";

	@Test
	public void testSendMessage() {
		try {
			// 打开连接和创建频道
			Connection connection = ConnectionUtils.getConnection();
			Channel channel = connection.createChannel();
			// 声明一个队列
			channel.queueDeclare(QUEUE_NAME, false, false, false, null);
			// 创建连接
			String msg = "Hello World yaohj123!";
//			String msg1 = "Hello World yaohj456!";
			// 发送消息到队列中
			for(int i = 0; i < 1000; i++){
				msg = String.valueOf(i);
				channel.basicPublish("", QUEUE_NAME, null, msg.getBytes());
			}
//			channel.basicPublish("", QUEUE_NAME, null, msg1.getBytes());
			// 关闭通道和连接
			channel.close();
			connection.close();
		} catch (IOException e) {
			e.printStackTrace();
		} catch (TimeoutException e) {
			e.printStackTrace();
		}
	}
}

9，新建消费者的类

package rabbitmq;

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

import com.rabbitmq.client.AMQP;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Consumer;
import com.rabbitmq.client.DefaultConsumer;
import com.rabbitmq.client.Envelope;

public class receiver {

	private static final String QUEUE_NAME = "test_simple_queue";

	public static void main(String[] args) {
		try {
			// 打开连接和创建频道
			Connection connection = ConnectionUtils.getConnection();
			Channel channel = connection.createChannel();
			// 告诉服务器我们需要那个频道的消息，如果频道中有消息，就会执行回调函数handleDelivery
			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("Customer Received:" + message);
				}
			};
			// 自动回复队列应答 -- RabbitMQ中的消息确认机制
			channel.basicConsume(QUEUE_NAME, true, consumer);
		} catch (IOException e) {
			e.printStackTrace();
		} catch (TimeoutException e) {
			e.printStackTrace();
		}
	}
}

10，运行
先运行生产者，后运行消费者，OK，大功告成！

生产的内容，消费者自动全部收到
Customer Received:0
Customer Received:1
Customer Received:2
Customer Received:3
Customer Received:4
Customer Received:5
Customer Received:6
Customer Received:7
