篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了springboot+rabbitmq整合示例程相关的知识，希望对你有一定的参考价值。

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=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.publisher-confirms=true
spring.rabbitmq.virtual-host=/

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，binding_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，binding_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：

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

3、多生产者-多消费者

生产者1：

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);
    }

}

生产者2：

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 HelloSender2 {

    @Autowired
    private AmqpTemplate rabbitTemplate;

    public void send(String msg) {
        String sendMsg = msg + new Date();
        System.out.println("Sender2 : " + 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:

    /**
     * 多生产者-多消费者
     */
    @PostMapping("/manyToMany")
    public void manyToMany() {
        for(int i=0;i<10;i++){
            helloSender1.send("hellomsg:"+i);
            helloSender2.send("hellomsg:"+i);
        }
        
    }

用post方式执行：

http://127.0.0.1:8080/rabbit/manyToMany

结果如下：

Sender1 : hellomsg:0Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:0Fri May 12 09:08:50 CST 2017
Sender1 : hellomsg:1Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:1Fri May 12 09:08:50 CST 2017
Sender1 : hellomsg:2Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:2Fri May 12 09:08:50 CST 2017
Sender1 : hellomsg:3Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:3Fri May 12 09:08:50 CST 2017
Sender1 : hellomsg:4Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:4Fri May 12 09:08:50 CST 2017
Sender1 : hellomsg:5Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:5Fri May 12 09:08:50 CST 2017
Sender1 : hellomsg:6Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:6Fri May 12 09:08:50 CST 2017
Sender1 : hellomsg:7Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:7Fri May 12 09:08:50 CST 2017
Sender1 : hellomsg:8Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:8Fri May 12 09:08:50 CST 2017
Sender1 : hellomsg:9Fri May 12 09:08:50 CST 2017
Sender2 : hellomsg:9Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:0Fri May 12 09:08:50 CST 2017
Receiver1  : hellomsg:0Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:1Fri May 12 09:08:50 CST 2017
Receiver1  : hellomsg:1Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:2Fri May 12 09:08:50 CST 2017
Receiver1  : hellomsg:2Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:3Fri May 12 09:08:50 CST 2017
Receiver1  : hellomsg:3Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:4Fri May 12 09:08:50 CST 2017
Receiver1  : hellomsg:4Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:5Fri May 12 09:08:50 CST 2017
Receiver1  : hellomsg:5Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:6Fri May 12 09:08:50 CST 2017
Receiver1  : hellomsg:6Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:7Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:8Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:8Fri May 12 09:08:50 CST 2017
Receiver1  : hellomsg:7Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:9Fri May 12 09:08:50 CST 2017
Receiver2  : hellomsg:9Fri May 12 09:08:50 CST 2017

和一对多一样，接收端仍然会均匀接收到消息

4、实体类传输

springboot完美的支持对象的发送和接收，不需要格外的配置。

实体类（必须实现序列化接口）：

package com.rabbit.user;

import java.io.Serializable;

public class User implements Serializable{
        private String name;
        private String pass;
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getPass() {
            return pass;
        }
        public void setPass(String pass) {
            this.pass = pass;
        }
}

生产者：

package com.rabbit.user;

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 UserSender {

    @Autowired
    private AmqpTemplate rabbitTemplate;

    public void send() {
        User user=new User();
        user.setName("hzb");
        user.setPass("123456789");
        System.out.println("user send : " + user.getName()+"/"+user.getPass());
        this.rabbitTemplate.convertAndSend("userQueue", user);
    }

}

消费者：

package com.rabbit.user;

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

@Component
@RabbitListener(queues = "userQueue")
public class UserReceiver {

    @RabbitHandler
    public void process(User user) {
        System.out.println("user receive  : " + user.getName()+"/"+user.getPass());
    }

}

controller:

    /**
     * 实体类传输测试
     */
    @PostMapping("/userTest")
    public void userTest() {
           userSender.send();
    }

用post方式执行：

http://127.0.0.1:8080/rabbit/userTest

结果如下：

user send : hzb/123456789
user receive  : hzb/123456789

5、topic ExChange示例

topic 是RabbitMQ中最灵活的一种方式，可以根据binding_key自由的绑定不同的队列

首先对topic规则配置，这里使用两个队列来测试（也就是在Application类中创建和绑定的topic.message和topic.messages两个队列），其中topic.message的bindting_key为

“topic.message”，topic.messages的binding_key为“topic.#”；

生产者：

package com.rabbit.topic;

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 TopicSender {

    @Autowired
    private AmqpTemplate rabbitTemplate;

    public void send() {
        String msg1 = "I am topic.mesaage msg======";
        System.out.println("sender1 : " + msg1);
        this.rabbitTemplate.convertAndSend("exchange", "topic.message", msg1);
        
        String msg2 = "I am topic.mesaages msg########";
        System.out.println("sender2 : " + msg2);
        this.rabbitTemplate.convertAndSend("exchange", "topic.messages", msg2);
    }

}

消费者1（topic.message）

package com.rabbit.topic;

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

@Component
@RabbitListener(queues = "topic.message")
public class topicMessageReceiver {

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

}

消费者２（topic.messages）

package com.rabbit.topic;

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

@Component
@RabbitListener(queues = "topic.messages")
public class topicMessagesReceiver {

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

}

controller:

    /**
     * topic exchange类型rabbitmq测试
     */
    @PostMapping("/topicTest")
    public void topicTest() {
           topicSender.send();
    }

用post方式执行：

http://127.0.0.1:8080/rabbit/topicTest

结果如下：

sender1 : I am topic.mesaage msg======
sender2 : I am topic.mesaages msg########
topicMessageReceiver  : I am topic.mesaage msg======
topicMessagesReceiver  : I am topic.mesaage msg======
topicMessagesReceiver  : I am topic.mesaages msg########

由以上结果可知：sender1发送的消息,routing_key是“topic.message”，所以exchange里面的绑定的binding_key是“topic.message”，topic.＃都符合路由规则;所以sender1

发送的消息，两个队列都能接收到；

sender2发送的消息，routing_key是“topic.messages”，所以exchange里面的绑定的binding_key只有topic.＃都符合路由规则;所以sender2发送的消息只有队列

topic.messages能收到。

6、fanout ExChange示例

Fanout 就是我们熟悉的广播模式或者订阅模式，给Fanout转发器发送消息，绑定了这个转发器的所有队列都收到这个消息。

这里使用三个队列来测试（也就是在Application类中创建和绑定的fanout.A、fanout.B、fanout.C）这三个队列都和Application中创建的fanoutExchange转发器绑定。

生产者：

package com.rabbit.fanout;

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 FanoutSender {

    @Autowired
    private AmqpTemplate rabbitTemplate;

    public void send() {
        String msgString="fanoutSender :hello i am hzb";
        System.out.println(msgString);
        this.rabbitTemplate.convertAndSend("fanoutExchange","abcd.ee", msgString);
    }

}

消费者A:

package com.rabbit.fanout;

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

@Component
@RabbitListener(queues = "fanout.A")
public class FanoutReceiverA {

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

}

消费者Ｂ：

package com.rabbit.fanout;

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

@Component
@RabbitListener(queues = "fanout.B")
public class FanoutReceiverB {

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

}

消费者C:

package com.rabbit.fanout;

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

@Component
@RabbitListener(queues = "fanout.C")
public class FanoutReceiverC {

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

}

controller:

    /**
     * fanout exchange类型rabbitmq测试
     */
    @PostMapping("/fanoutTest")
    public void fanoutTest() {
           fanoutSender.send();
    }

用post方式执行：

http://127.0.0.1:8080/rabbit/fanoutTest

结果如下：

fanoutSender :hello i am hzb
FanoutReceiverC  : fanoutSender :hello i am hzb
FanoutReceiverB  : fanoutSender :hello i am hzb
FanoutReceiverA  : fanoutSender :hello i am hzb

由以上结果可知：就算fanoutSender发送消息的时候，指定了routing_key为"abcd.ee"，但是所有接收者都接受到了消息

7、带callback的消息发送

增加回调处理，这里不再使用application.properties默认配置的方式，会在程序中显示的使用文件中的配置信息。该示例中没有新建队列和exchange，用的是第5节中的topic.messages队列和exchange转发器。消费者也是第5节中的topicMessagesReceiver

rabbitmq配置类：

package com.rabbit.callback;

import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.beans.factory.config.ConfigurableBeanFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Scope;

public class RabbitConfig {
    
    @Value("${spring.rabbitmq.host}")
    private String addresses;
    
    @Value("${spring.rabbitmq.port}")
    private String port;

    @Value("${spring.rabbitmq.username}")
    private String username;

    @Value("${spring.rabbitmq.password}")
    private String password;

    @Value("${spring.rabbitmq.virtual-host}")
    private String virtualHost;

    @Value("${spring.rabbitmq.publisher-confirms}")
    private boolean publisherConfirms;
    
    @Bean
    public ConnectionFactory connectionFactory() {

        CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
        connectionFactory.setAddresses(addresses+":"+port);
        connectionFactory.setUsername(username);
        connectionFactory.setPassword(password);
        connectionFactory.setVirtualHost(virtualHost);
        /** 如果要进行消息回调，则这里必须要设置为true */
        connectionFactory.setPublisherConfirms(publisherConfirms);
        return connectionFactory;
    }
    
    @Bean
    /** 因为要设置回调类，所以应是prototype类型，如果是singleton类型，则回调类为最后一次设置 */
    @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
    public RabbitTemplate rabbitTemplatenew() {
        RabbitTemplate template = new RabbitTemplate(connectionFactory());
        return template;
    }

}

生产者：

package com.rabbit.callback;

import java.util.Date;
import java.util.UUID;

import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.rabbit.support.CorrelationData;
import org.springframework.beans.factory.annotation.Autowired;

@Component
public class CallBackSender implements  RabbitTemplate.ConfirmCallback{
    @Autowired
    private RabbitTemplate rabbitTemplatenew;
    public void send() {
        
        rabbitTemplatenew.setConfirmCallback(this);
        String msg="callbackSender : i am callback sender";
        System.out.println(msg );
        CorrelationData correlationData = new CorrelationData(UUID.randomUUID().toString());  
        System.out.println("callbackSender UUID: " + correlationData.getId());
