关于什么是rabbitmq，请看另一篇文：

http://www.cnblogs.com/boshen-hzb/p/6840064.html

一、新建maven工程：springboot-rabbitmq

二、引入springboot和rabbitmq的依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.springboot.rabbitmq</groupId>
  <artifactId>springboot-rabbitmq</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>springboot-rabbitmq</name>
  <description>springboot-rabbitmq</description>
  
  <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.1.RELEASE</version>
  </parent>
  <dependencies>
     <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
     </dependency>
     <dependency>  
            <groupId>org.springframework.boot</groupId>  
            <artifactId>spring-boot-starter-test</artifactId>  
            <scope>test</scope>  
     </dependency>  
     <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
    </dependency>
  </dependencies>
</project>

spring-boot-starter-test是为了后面写测试类用，

spring-boot-starter-amqp才是真正的使用rabbitmq的依赖

三、在src/main/resources里面新增application.properties
该配置文件主要是对rabbimq的配置信息

spring.application.name=springboot-rabbitmq
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=15672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

四、新建springboot主类Application

该类初始化创建队列、转发器，并把队列绑定到转发器

package com.rabbit;

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class Application {
    final static String queueName = "hello";

    @Bean
    public Queue helloQueue() {
        return new Queue("hello");
    }
    
    @Bean
    public Queue userQueue() {
        return new Queue("user");
    }
    
    //===============以下是验证topic Exchange的队列==========
    @Bean
    public Queue queueMessage() {
        return new Queue("topic.message");
    }

    @Bean
    public Queue queueMessages() {
        return new Queue("topic.messages");
    }
  //===============以上是验证topic Exchange的队列==========
    
    
    //===============以下是验证Fanout Exchange的队列==========
    @Bean
    public Queue AMessage() {
        return new Queue("fanout.A");
    }

    @Bean
    public Queue BMessage() {
        return new Queue("fanout.B");
    }

    @Bean
    public Queue CMessage() {
        return new Queue("fanout.C");
    }
    //===============以上是验证Fanout Exchange的队列==========
    

    @Bean
    TopicExchange exchange() {
        return new TopicExchange("exchange");
    }
    @Bean
    FanoutExchange fanoutExchange() {
        return new FanoutExchange("fanoutExchange");
    }

    /**
     * 将队列topic.message与exchange绑定，routing_key为topic.message,就是完全匹配
     * @param queueMessage
     * @param exchange
     * @return
     */
    @Bean
    Binding bindingExchangeMessage(Queue queueMessage, TopicExchange exchange) {
        return BindingBuilder.bind(queueMessage).to(exchange).with("topic.message");
    }

    /**
     * 将队列topic.messages与exchange绑定，routing_key为topic.#,模糊匹配
     * @param queueMessage
     * @param exchange
     * @return
     */
    @Bean
    Binding bindingExchangeMessages(Queue queueMessages, TopicExchange exchange) {
        return BindingBuilder.bind(queueMessages).to(exchange).with("topic.#");
    }
    
    @Bean
    Binding bindingExchangeA(Queue AMessage,FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(AMessage).to(fanoutExchange);
    }

    @Bean
    Binding bindingExchangeB(Queue BMessage, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(BMessage).to(fanoutExchange);
    }

    @Bean
    Binding bindingExchangeC(Queue CMessage, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(CMessage).to(fanoutExchange);
    }
    
    
   
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

五、各种情景实现

1、最简单的hello生产和消费实现（单生产者和单消费者）

生产者：

package com.rabbit.hello;

import java.util.Date;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class HelloSender1 {

    @Autowired
    private AmqpTemplate rabbitTemplate;

    public void send() {
        String sendMsg = "hello1 " + new Date();
        System.out.println("Sender1 : " + sendMsg);
        this.rabbitTemplate.convertAndSend("helloQueue", sendMsg);
    }

}

消费者:

package com.rabbit.hello;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@RabbitListener(queues = "helloQueue")
public class HelloReceiver1 {

    @RabbitHandler
    public void process(String hello) {
        System.out.println("Receiver1  : " + hello);
    }

}

controller：

package com.rabbit.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.rabbit.hello.HelloSender1;

@RestController
@RequestMapping("/rabbit")
public class RabbitTest {
    
    @Autowired
    private HelloSender1 helloSender1;
    @Autowired
    private HelloSender1 helloSender2;
    
    @PostMapping("/hello")
    public void hello() {
        helloSender1.send();
    }
}

启动程序，执行：

技术分享

结果如下：

Sender1 : hello1 Thu May 11 17:23:31 CST 2017
Receiver2  : hello1 Thu May 11 17:23:31 CST 2017

2、单生产者-多消费者

生产者：

package com.rabbit.hello;

import java.util.Date;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class HelloSender1 {

    @Autowired
    private AmqpTemplate rabbitTemplate;

    public void send(String msg) {
        String sendMsg = msg + new Date();
        System.out.println("Sender1 : " + sendMsg);
        this.rabbitTemplate.convertAndSend("helloQueue", sendMsg);
    }

}

消费者1：

package com.rabbit.hello;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@RabbitListener(queues = "helloQueue")
public class HelloReceiver1 {

    @RabbitHandler
    public void process(String hello) {
        System.out.println("Receiver1  : " + hello);
    }

}

消费者2：

package com.rabbit.hello;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@RabbitListener(queues = "helloQueue")
public class HelloReceiver2 {

    @RabbitHandler
    public void process(String hello) {
        System.out.println("Receiver2  : " + hello);
    }

}

controller:

package com.rabbit.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.rabbit.hello.HelloSender1;

@RestController
@RequestMapping("/rabbit")
public class RabbitTest {
    
    @Autowired
    private HelloSender1 helloSender1;
    @Autowired
    private HelloSender1 helloSender2;
    
    @PostMapping("/hello")
    public void hello() {
        helloSender1.send("hello1");
    }
    
    /**
     * 单生产者-多消费者
     */
    @PostMapping("/oneToMany")
    public void oneToMany() {
        for(int i=0;i<10;i++){
            helloSender1.send("hellomsg:"+i);
        }
        
    }
}

用post方式执行：

http://127.0.0.1:8080/rabbit/oneToMany

结果如下：

Sender1 : hellomsg:0Thu May 11 17:37:59 CST 2017
Sender1 : hellomsg:1Thu May 11 17:37:59 CST 2017
Sender1 : hellomsg:2Thu May 11 17:37:59 CST 2017
Sender1 : hellomsg:3Thu May 11 17:37:59 CST 2017
Sender1 : hellomsg:4Thu May 11 17:37:59 CST 2017
Sender1 : hellomsg:5Thu May 11 17:37:59 CST 2017
Sender1 : hellomsg:6Thu May 11 17:37:59 CST 2017
Sender1 : hellomsg:7Thu May 11 17:37:59 CST 2017
Sender1 : hellomsg:8Thu May 11 17:37:59 CST 2017
Sender1 : hellomsg:9Thu May 11 17:37:59 CST 2017
Receiver2  : hellomsg:1Thu May 11 17:37:59 CST 2017
Receiver1  : hellomsg:0Thu May 11 17:37:59 CST 2017
Receiver1  : hellomsg:3Thu May 11 17:37:59 CST 2017
Receiver1  : hellomsg:4Thu May 11 17:37:59 CST 2017
Receiver1  : hellomsg:5Thu May 11 17:37:59 CST 2017
Receiver2  : hellomsg:2Thu May 11 17:37:59 CST 2017
Receiver1  : hellomsg:6Thu May 11 17:37:59 CST 2017
Receiver2  : hellomsg:7Thu May 11 17:37:59 CST 2017
Receiver2  : hellomsg:8Thu May 11 17:37:59 CST 2017
Receiver1  : hellomsg:9Thu May 11 17:37:59 CST 2017

从以上结果可知，生产者发送的10条消息，分别被两个消费者接收了
