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;

        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);

          };

    }
