环境搭建

这里使用gradle项目

apply plugin: 'eclipse'
apply plugin: 'maven'
apply plugin: 'java'
    
sourceCompatibility = 1.8
​
[compileJava,compileTestJava,javadoc]*.options*.encoding = 'UTF-8' 
​
repositories {
   
    maven{url 'http://maven.aliyun.com/nexus/content/groups/public/'}
    mavenCentral()
    jcenter()
}
dependencies {
​
    compile group: 'com.rabbitmq', name: 'amqp-client', version: '4.1.0'
    compile group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.25'
}

Hello World模式(点对点)

package com.rabbitmq.www.helloworld;



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

public class Send {
    
    
    private final static String QUEUE_NAME = "hello";
    
    
    private final static String HOST_ADDR = "172.18.112.102";
    
    
    
    public static void main(String[] args) throws Exception {
        
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost(HOST_ADDR);
        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());
        System.out.println("发送消息 ： " + message + "'");
        channel.close();
        connection.close();
        
    }
        
    

}

package com.rabbitmq.www.helloworld;

import java.io.IOException;

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

public class Recv {

    private final static String QUEUE_NAME = "hello";
    
    private final static String HOST_ADDR = "172.18.112.102";
    
    public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub

        
        
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost(HOST_ADDR);
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);
        System.out.println("等待消息");
        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("接受消息 ： " + message);
            }
          };
          channel.basicConsume(QUEUE_NAME, true, consumer);

    }
