rabbitmq-workqueue模型(1对多模型)

239 阅读1分钟

helloworld项目是直连模型,(1对1,1个生产者和1个消费者)

durable参数说明:

是否持久化队列,重启rabbitmq后,durable=false会丢失队列;druable=true,重启rabbitmq,消息会丢失
消费者的绑定参数与生产者要一致。都为druable=true,autoDelete=false,exclusive=false,arguments=null,queue。

workqueue模型,(1对多):

RabbitMQUtils.java

package com.gavin.utils; 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 RabbitMQUtils {    private static ConnectionFactory connectionFactory;    static{        connectionFactory = new ConnectionFactory();        connectionFactory.setHost("127.0.0.1");        connectionFactory.setPort(5672);        connectionFactory.setVirtualHost("/");        connectionFactory.setUsername("guest");        connectionFactory.setPassword("guest");    }     public static Connection getConnection() throws IOException, TimeoutException {       return connectionFactory.newConnection();    }    public static void close(Channel channel,Connection connection) throws IOException, TimeoutException {        if (channel != null) channel.close();        if(connection != null) connection.close();    }}

生产者

package com.gavin.mq.workqueue; import com.gavin.utils.RabbitMQUtils;import com.rabbitmq.client.Channel;import com.rabbitmq.client.Connection;import com.rabbitmq.client.MessageProperties;import org.junit.Test; import java.io.IOException;import java.util.concurrent.TimeoutException; /** * 工作队列模型:让多个消费绑定到一个队列,共同消费队列中的消息 * 多个消费者平均分配 */public class WorkProvider {    @Test    public void testSendMessage() throws IOException, TimeoutException {         Connection connection = RabbitMQUtils.getConnection();        Channel channel = connection.createChannel();        channel.queueDeclare("work",true,false,false,null);        for(int i = 0;i<10;i++){            channel.basicPublish("","work", MessageProperties.PERSISTENT_BASIC,(i+"hello work queue").getBytes());        }        RabbitMQUtils.close(channel,connection);    }}

消费者1

package com.gavin.mq.workqueue; import com.gavin.utils.RabbitMQUtils;import com.rabbitmq.client.*; import java.io.IOException;import java.util.concurrent.TimeoutException; public class WorkConsumer {    public static void main(String[] args) throws IOException, TimeoutException {        Connection connection = RabbitMQUtils.getConnection();        Channel channel = connection.createChannel();        channel.queueDeclare("work",true,false,false,null);        channel.basicConsume("work",true,new DefaultConsumer(channel){            @Override            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {                System.out.println(new String(body));            }        });    }}

消费者2

package com.gavin.mq.workqueue; import com.gavin.utils.RabbitMQUtils;import com.rabbitmq.client.*; import java.io.IOException;import java.util.concurrent.TimeoutException; public class WorkConsumer2 {    public static void main(String[] args) throws IOException, TimeoutException {        Connection connection = RabbitMQUtils.getConnection();        Channel channel = connection.createChannel();        channel.queueDeclare("work",true,false,false,null);        channel.basicConsume("work",true,new DefaultConsumer(channel){            @Override            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {                System.out.println("consumer2:"+new String(body));            }        });    }}
