Hello World模式

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();

     }

 }

              System.out.println("接受消息 ： " + message);

            }

          };
