使用架构

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：
