Springboot整合二 集成 rabbitmq

1、在application.yml文件中进行RabbitMQ的相关配置
先上代码

spring:
  rabbitmq:
    host: 192168.21.11
    port:
    username: guest
    password: password
    publisher-confirms: true    #  消息发送到交换机确认机制,是否确认回调
    virtual-host: / #默认主机

#自定义参数
defineProps:
 rabbitmq: 
  wechat: 
   template: 
    topic: wxmsg.topic
    queue: wxmsg.queue
    # *表号匹配一个word，#匹配多个word和路径，路径之间通过.隔开
    queue1_pattern: wxmsg.message.exchange.queue.#
    # *表号匹配一个word，#匹配多个word和路径，路径之间通过.隔开
    queue2_pattern: wxmsg.message.exchange.queue.#

2. 项目启动配置

       大家可以看到上图中的config包，这里就是相关配置类

下面，就这三个配置类，做下说明：(这里需要大家对RabbitMQ有一定的了解，知道生产者、消费者、消息交换机、队列等)

ExchangeConfig    消息交换机配置

package com.space.rabbitmq.config;

import org.springframework.amqp.core.DirectExchange;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * 消息交换机配置  可以配置多个
 */
@Configuration
public class ExchangeConfig {
    @Value("${defineProps.rabbitmq.wechat.template.topic}")
    private String templateTopic;

    /**
     *   1.定义topic exchange，绑定路由
     *   2.direct交换器相对来说比较简单，匹配规则为：如果路由键匹配，消息就被投送到相关的队列
     *     fanout交换器中没有路由键的概念，他会把消息发送到所有绑定在此交换器上面的队列中。
     *     topic交换器你采用模糊匹配路由键的原则进行转发消息到队列中
     *   3.durable="true" rabbitmq重启的时候不需要创建新的交换机
     *   4.autoDelete:false ,默认不自动删除
     *   5.key: queue在该topic exchange中的key值，当消息符合topic exchange中routing_key规则，
     *   消息将会转发给queue参数指定的消息队列
     */
    public TopicExchange topicExchange(){
        return new TopicExchange(templateTopic, true, false);
    }
}

QueueConfig  队列配置

package com.space.rabbitmq.config;

import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * 队列配置  可以配置多个队列
 */
@Configuration
public class QueueConfig {

    @Bean
    public Queue firstQueue() {
        /**
         durable="true" 持久化 rabbitmq重启的时候不需要创建新的队列
         auto-delete 表示消息队列没有在使用时将被自动删除 默认是false
         exclusive  表示该消息队列是否只在当前connection生效,默认是false
         */
        return new Queue("queue1",true,false,false);
    }

    @Bean
    public Queue secondQueue() {
        return new Queue("queue2",true,false,false);
    }
}

RabbitMqConfig RabbitMq配置

package com.space.rabbitmq.config;

import com.space.rabbitmq.mqcallback.MsgSendConfirmCallBack;
import org.springframework.amqp.core.AcknowledgeMode;
import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;

/**

@Configuration

    private String username;

    private String password;
    @Value("${spring.rabbitmq.virtual-host}")
    private String vhost;
    
    @Value("${defineProps.rabbitmq.wechat.template.queue1_pattern}")
    private String queue1_pattern;
    @Value("${defineProps.rabbitmq.wechat.template.queue2_pattern}")
    private String queue2_pattern;

    @Autowired
    private QueueConfig queueConfig;
    @Autowired
    private ExchangeConfig exchangeConfig;

    /**
     * 连接工厂
     */
    @Bean
    public ConnectionFactory connectionFactory() {
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory(host, port);
        connectionFactory.setUsername(username);
        connectionFactory.setPassword(password);
        connectionFactory.setVirtualHost(vhost);
        return connectionFactory;
    }

    @Bean
    public RabbitTemplate rabbitTemplate(){
    	return new RabbitTemplate(connectionFactory());
    }/**
     将消息队列1和交换机进行绑定
     */
    @Bean
    public Binding binding_one() {
        return BindingBuilder.bind(queueConfig.firstQueue()).to(exchangeConfig.topicExchange()).with(queue1_pattern);
    }

    /**
     * 将消息队列2和交换机进行绑定
     */
    @Bean
    public Binding binding_two() {
        return BindingBuilder.bind(queueConfig.secondQueue()).to(exchangeConfig.topicExchange()).with(queue2_pattern);
    }

    /**
     * queue listener  观察 监听模式
     * 当有消息到达时会通知监听在对应的队列上的监听对象
     * @return
     */
    @Bean
    public SimpleMessageListenerContainer simpleMessageListenerContainer_one(){
        SimpleMessageListenerContainer simpleMessageListenerContainer = new SimpleMessageListenerContainer(connectionFactory);
        simpleMessageListenerContainer.addQueues(queueConfig.firstQueue());
        simpleMessageListenerContainer.setExposeListenerChannel(true);
        simpleMessageListenerContainer.setMaxConcurrentConsumers();
        simpleMessageListenerContainer.setConcurrentConsumers();
        simpleMessageListenerContainer.setAcknowledgeMode(AcknowledgeMode.MANUAL); //设置确认模式手工确认
        simpleMessageListenerContainer.setMessageListener(wechatPushMessageListener());
        return simpleMessageListenerContainer;
    }

    /**
     * 配置消费者bean
     * @return
     */
    @Bean
    public WechatPushMessageConsumer wechatPushMessageListener(){
    	return new WechatPushMessageConsumer(redisUtil, mqMsgExceptionRemote, wechatAppID, wechatAppSecret);
    }

    /**

     * @return
     */
    @Bean
    public RabbitTemplate rabbitTemplate() {
        RabbitTemplate template = new RabbitTemplate(connectionFactory);
        /**若使用confirm-callback或return-callback，
         * 必须要配置publisherConfirms或publisherReturns为true
         * 每个rabbitTemplate只能有一个confirm-callback和return-callback
         */
        template.setConfirmCallback(msgSendConfirmCallBack());
        //template.setReturnCallback(msgSendReturnCallback());
        /**
         * 使用return-callback时必须设置mandatory为true，或者在配置中设置mandatory-expression的值为true，

         */
        //  template.setMandatory(true);
        return template;
    }

    /**

     * @return
     */
    @Bean
    public MsgSendConfirmCallBack msgSendConfirmCallBack(){
        return new MsgSendConfirmCallBack();
    }

}

消息回调

package com.space.rabbitmq.mqcallback;

import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.rabbit.support.CorrelationData;

/**
 * 消息发送到交换机确认机制
 * @author zhuzhe
 * @date 2018/5/25 15:53
 * @email 1529949535@qq.com
 */
public class MsgSendConfirmCallBack implements RabbitTemplate.ConfirmCallback {

    @Override
    public void confirm(CorrelationData correlationData, boolean ack, String cause) {
        System.out.println("MsgSendConfirmCallBack  , 回调id:" + correlationData);
        if (ack) {
            System.out.println("消息消费成功");
        } else {
            System.out.println("消息消费失败:" + cause+"\n重新发送");
        }
    }
}

生产者/消息发送者

package com.space.rabbitmq.sender;

import com.space.rabbitmq.config.RabbitMqConfig;
import lombok.extern.slf4j.Slf4j;
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;

/**
 * 消息发送  生产者1
 * @author zhuzhe
 * @date 2018/5/25 14:28
 * @email 1529949535@qq.com
 */
@Slf4j
@Component
public class FirstSender {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    /**
     * 发送消息
     * @param uuid
     * @param message  消息
     */
    public void send(String uuid,Object message) {
        CorrelationData correlationId = new CorrelationData(uuid);
        rabbitTemplate.convertAndSend(RabbitMqConfig.EXCHANGE, RabbitMqConfig.ROUTINGKEY2,
                message, correlationId);
    }
}

消费者

方式一（使用注解）： 

package com.space.rabbitmq.receiver;

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

/**
 * 消息消费者1
 * @author zhuzhe
 * @date 2018/5/25 17:32
 * @email 1529949535@qq.com
 */
@Component
public class FirstConsumer {

    @RabbitListener(queues = {"first-queue","second-queue"}, containerFactory = "rabbitListenerContainerFactory")
    public void handleMessage(String message) throws Exception {
        // 处理消息
        System.out.println("FirstConsumer {} handleMessage :"+message);
    }
}

方式二（利用配置）：
package com.space.rabbitmq.receiver;

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

/**
 * 消息消费者1
 */public class WechatPushMessageConsumer extends BaseMessageConsumer implements ChannelAwareMessageListener
   
	@Override
	public void onMessage(Message message, Channel channel) throws Exception {
　　　　　　System.out.println("接收到的消息：" + message.getBody());
　　　　}
}

消息接收两种方式：

@RabbitListener @RabbitHandler 及 消息序列化
