7.TestController.java

        s.setName("zhangsan");
        s.setAddress("wuhan");

8.MainApplication.java

package com.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Created by admin on 2017/6/1 11:19.
 */
@SpringBootApplication
public class MainApplication {
    public static void main(String[] args) {
        System.getProperties().put("test", "test");
        SpringApplication.run(MainApplication.class, args);

    }
}

9.application.yml

server:
    address: 192.168.200.117 #自己主机的IP地址
    port: 8000 #端口
spring:
  rabbitmq:
    addresses: 192.168.200.119:5672 #MQ IP 和 端口
    username: admin #MQ登录名
    password: 123456 #MQ登录密码
    virtual-host: test #MQ的虚拟主机名称

10.build.gradle

group ‘rabbitmqtest‘
version ‘1.0-SNAPSHOT‘

apply plugin: ‘java‘

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: ‘junit‘, name: ‘junit‘, version: ‘4.11‘
    testCompile("org.springframework.boot:spring-boot-starter-test:1.3.5.RELEASE")
    compile("org.springframework.boot:spring-boot-starter-web:1.3.5.RELEASE")
    compile(group: ‘org.springframework.amqp‘, name: ‘spring-rabbit‘, version: "1.6.1.RELEASE")
}

11.settings.gradle

rootProject.name = ‘rabbitmqtest‘

页面访问 192.168.200.117:8000/test/send  可以看到控制台有日志输出，发送的消息立即消费掉了

MQ的队列里面也是空的

如果把消费者的代码注掉，再访问刚才的 url 地址 队列里面就会多一条
