1，application.properties对rabbitmq的配置

#对于rabbitMQ的支持
########################################################
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

2，配置RabbitConfig

package com.lc.config;

import com.lc.Component.ComponentProperties;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.core.*;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;

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.Configuration;
import org.springframework.context.annotation.Scope;
/**

@Configuration
public class RabbitConfig {
    private final Logger logger = LoggerFactory.getLogger(this.getClass());
   @Value("${spring.rabbitmq.host}")
    private String host;
    @Value("${spring.rabbitmq.port}")
    private int port;
    @Value("${spring.rabbitmq.username}")
    private String username;
    @Value("${spring.rabbitmq.password}")
    private String password;


    public static final String EXCHANGE_A = "my-mq-exchange_A";
    public static final String EXCHANGE_B = "my-mq-exchange_B";
    public static final String EXCHANGE_C = "my-mq-exchange_C";

    public static final String QUEUE_A = "QUEUE_A";
    public static final String QUEUE_B = "QUEUE_B";
    public static final String QUEUE_C = "QUEUE_C";

    public static final String ROUTINGKEY_A = "spring-boot-routingKey_A";
    public static final String ROUTINGKEY_B = "spring-boot-routingKey_B";
    public static final String ROUTINGKEY_C = "spring-boot-routingKey_C";

    public final static String TopicMsg= "topic.message";
    public final static String TopicMsgs = "topic.messages";

    @Bean
    public ConnectionFactory connectionFactory() {
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory(host,port);
        connectionFactory.setUsername(username);
        connectionFactory.setPassword(password);
        connectionFactory.setVirtualHost("/");
        connectionFactory.setPublisherConfirms(true);
        return connectionFactory;
    }

    @Bean
    @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
    //必须是prototype类型
    public RabbitTemplate rabbitTemplate() {
        RabbitTemplate template = new RabbitTemplate(connectionFactory());
        return template;
    }

    /**
     * 针对消费者配置
     * 1. 设置交换机类型
     * 2. 将队列绑定到交换机
     FanoutExchange: 将消息分发到所有的绑定队列，无routingkey的概念
     HeadersExchange ：通过添加属性key-value匹配
     DirectExchange:按照routingkey分发到指定队列
     TopicExchange:多关键字匹配
     */
    @Bean
    public DirectExchange defaultExchange() {
        return new DirectExchange(EXCHANGE_A);
    }
    @Bean
    TopicExchange exchange() {
        return new TopicExchange("exchange");
    }
    @Bean
    FanoutExchange fanoutExchange() {
        return new FanoutExchange("fanoutExchange");
    }

    /**
     * 获取队列A
     */
    @Bean
    public Queue queueA() {
        return new Queue(QUEUE_A, true); //队列持久
    }
    /**
     * 获取队列B
     */
    @Bean
    public Queue queueB() {
        return new Queue(QUEUE_B, true); //队列持久
    }
    /**
     * 获取Topic队列C
     */
    @Bean
    public Queue queueC() {
        return new Queue(TopicMsg, true); //队列持久
    }
    @Bean
    public Queue queueFanoutA() {
        return new Queue("fanout.A");
    }
    @Bean
    public Queue queueFanoutB() {
        return new Queue("fanout.B");
    }

    @Bean
    public Binding bindingA() {
        return BindingBuilder.bind(queueA()).to(defaultExchange()).with(RabbitConfig.ROUTINGKEY_A);
    }
    @Bean
    public Binding bindingB(){
        return BindingBuilder.bind(queueB()).to(defaultExchange()).with(RabbitConfig.ROUTINGKEY_B);
    }
    @Bean
    Binding bindingTopicMsg(Queue queueC, TopicExchange exchange)
    {

    }
    @Bean
    Binding bindingFanoutExchangeA(Queue queueFanoutA,FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(queueFanoutA).to(fanoutExchange);
    }
    @Bean
    Binding bindingFanoutExchangeB(Queue queueFanoutB,FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(queueFanoutB).to(fanoutExchange);
    }

}

3，Producer生产者

package com.lc.Producer;

import com.lc.config.RabbitConfig;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.rabbit.support.CorrelationData;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.UUID;

/**
 * @author liuchaoOvO on 2018/12/28
 */
@Component
public class MsgProducer implements RabbitTemplate.ConfirmCallback {
    private final Logger logger = LoggerFactory.getLogger(this.getClass());
    //由于rabbitTemplate的scope属性设置为ConfigurableBeanFactory.SCOPE_PROTOTYPE，所以不能自动注入
    private RabbitTemplate rabbitTemplate;
    /**
     * 构造方法注入rabbitTemplate
     */
    @Autowired
    public MsgProducer(RabbitTemplate rabbitTemplate) {
        this.rabbitTemplate = rabbitTemplate;
        rabbitTemplate.setConfirmCallback(this); //rabbitTemplate如果为单例的话，那回调就是最后设置的内容
    }
    public void sendMsg(String content) {
        CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());
        //把消息放入ROUTINGKEY_A对应的队列当中去，对应的是队列A
        rabbitTemplate.convertAndSend(RabbitConfig.EXCHANGE_A, RabbitConfig.ROUTINGKEY_A, content, correlationId);
    }
    public void sendTopicMsg(String content) {
        CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());
        rabbitTemplate.convertAndSend("exchange", RabbitConfig.TopicMsg, content, correlationId);
    }
    public void sendTopicMsgs(String content) {
        CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());
        rabbitTemplate.convertAndSend("exchange", RabbitConfig.TopicMsgs, content, correlationId);
    }
    public void sendFanoutMsgs(String content) {
        CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());
        System.out.println("Sender : " + content);
        rabbitTemplate.convertAndSend("fanoutExchange", "", content, correlationId);
    }

    /**
     * 回调
     */
    @Override
    public void confirm(CorrelationData correlationData, boolean ack, String cause) {
        logger.info(" 回调id:" + correlationData);
        if (ack) {
            logger.info("消息成功消费");
        } else {
            logger.info("消息消费失败:" + cause);
        }
    }
}

4，Receiver消费者

package com.lc.Receiver;

import com.lc.config.RabbitConfig;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

/**
 * @author liuchaoOvO on 2018/12/28
 */
@Component
@RabbitListener(queues = RabbitConfig.QUEUE_A)
public class MsgReceiver {

    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @RabbitHandler
    public void process(String content) {
        logger.info("接收处理队列A当中的消息： " + content);
    }

}
或者

package com.lc.Receiver;

import com.lc.config.RabbitConfig;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

/**
 * @author liuchaoOvO on 2018/12/28
 */
@Component
@RabbitListener(queues = RabbitConfig.TopicMsg)
public class MsgReceiverTopicOne
{

    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @RabbitHandler
    public void process(String content) {
        logger.info("接收处理MsgReceiverTopicOne当中的消息： " + content);
    }

}
或者

package com.lc.Receiver;

import com.lc.config.RabbitConfig;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

/**
 * @author liuchaoOvO on 2018/12/28
 */
@Component
@RabbitListener(queues = RabbitConfig.TopicMsg)
public class MsgReceiverTopicTwo
{

    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @RabbitHandler
    public void process(String content) {
        logger.info("接收处理MsgReceiverTopicTwo当中的消息： " + content);
    }

}
5，调用方式

在某个类文件对象中，注入生产者消息对象：
@Autowired
private MsgProducer  msgProducer;
执行相应的生产者函数逻辑代码：
例如：msgProducer.sendFanoutMsgs("sendFanoutMsgs===");

则在相应的，通过queue类型

@RabbitListener(queues = RabbitConfig.QUEUE_A)

例如对队列A的匹配下的消费者的

@RabbitHandler
public void process(String content) {
    logger.info("接收处理队列A当中的消息： " + content);
}

执行方法中处理相应的业务逻辑。
