操作003：工作队列模式
一、生产者代码
1、封装工具类
package com.atguigu.rabbitmq.util;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
public class ConnectionUtil {
public static final String HOST_ADDRESS = "192.168.200.100";
public static Connection getConnection() throws Exception {
// 定义连接工厂
ConnectionFactory factory = new ConnectionFactory();
// 设置服务地址
factory.setHost(HOST_ADDRESS);
// 端口
factory.setPort(5672);
//设置账号信息，用户名、密码、vhost
factory.setVirtualHost("/");
factory.setUsername("guest");
factory.setPassword("123456");
// 通过工程获取连接
Connection connection = factory.newConnection();
return connection;
}
public static void main(String[] args) throws Exception {
Connection con = ConnectionUtil.getConnection();
// amqp://guest@192.168.200.100:5672/
System.out.println(con);
con.close();
}
}
2、编写代码
package com.atguigu.rabbitmq.work;
import com.atguigu.rabbitmq.util.ConnectionUtil;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
public class Producer {
public static final String QUEUE_NAME = "work_queue";
public static void main(String[] args) throws Exception {
Connection connection = ConnectionUtil.getConnection();
Channel channel = connection.createChannel();
channel.queueDeclare(QUEUE_NAME,true,false,false,null);
for (int i = 1; i <= 10; i++) {
String body = i+"hello rabbitmq~~~";
channel.basicPublish("",QUEUE_NAME,null,body.getBytes());
}
channel.close();
connection.close();
}
}
3、发送消息效果
二、消费者代码
1、编写代码
创建Consumer1和Consumer2。Consumer2只是类名和打印提示不同，代码完全一样。
package com.atguigu.rabbitmq.work;
import com.atguigu.rabbitmq.util.ConnectionUtil;
import com.rabbitmq.client.*;
import java.io.IOException;
public class Consumer1 {
static final String QUEUE_NAME = "work_queue";
public static void main(String[] args) throws Exception {
Connection connection = ConnectionUtil.getConnection();
Channel channel = connection.createChannel();
channel.queueDeclare(QUEUE_NAME,true,false,false,null);
Consumer consumer = new DefaultConsumer(channel){
@Override
public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
System.out.println("Consumer1 body："+new String(body));
}
};
channel.basicConsume(QUEUE_NAME,true,consumer);
}
}
注意：运行的时候先启动两个消费端程序，然后再启动生产者端程序。
如果已经运行过生产者程序，则手动把work_queue队列删掉。
2、运行效果
最终两个消费端程序竞争结果如下：
