RabbitMQ 集成springboot 与 异步处理实战

1、集成springboot

1.1 添加 maven 依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.2.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<!--springboot集成rabbitmq-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

1.2 配置基本参数

server.port=8080
spring.application.name=springboot-rabbitmq
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
# 发送方确认
spring.rabbitmq.publisher-confirms=true
# 虚拟主机
spring.rabbitmq.virtual-host=/

1.3 配置类

在配置类中声明

• 创建连接工厂
• 声明 RabbitTemplate
• 声明交换器
• 声明队列
• 设置绑定关系
• 设置失败通知方法，发送者确认方法，失败者确认方法。

            System.out.println("UserReceiver----> 接收到消息：" + msg);

            channel.basicAck(message.getMessageProperties().getDeliveryTag(),
                    false);
            System.out.println("UserReceiver----> 消息已消费");

        } catch (Exception e) {
            channel.basicNack(message.getMessageProperties().getDeliveryTag(),
                    false, true);
            System.out.println("UserReceiver>>>>>>拒绝消息，要求Mq重新派发");
            e.printStackTrace();
            throw e;
        }
    }
}

1.6 topic 交换器，生产者 和 消费者

1.6.1 生产者

package com.h.rabbitmq.springboot.topic;

import com.h.rabbitmq.springboot.RmConst;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

/**
 * @author h
 * @Description 生产者-主题交换器
 * @createTime 2020年06月25日 20:18
 */
@Component
public class TopicSender {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    public void send() {
        String msg1 = "I am email mesaage msg======";
        System.out.println("TopicSender send the 1st : " + msg1);
        rabbitTemplate.convertAndSend(RmConst.EXCHANGE_TOPIC, RmConst.RK_EMAIL, msg1);

        String msg2 = "I am user mesaages msg########";
        System.out.println("TopicSender send the 2nd : " + msg2);
        rabbitTemplate.convertAndSend(RmConst.EXCHANGE_TOPIC, RmConst.RK_USER, msg2);

        String msg3 = "I am error mesaages msg";
        System.out.println("TopicSender send the 3rd : " + msg3);
        rabbitTemplate.convertAndSend(RmConst.EXCHANGE_TOPIC, "errorKey", msg3);
    }
}

1.6.2 消费者

package com.h.rabbitmq.springboot.topic;

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

/**
 * @author h
 * @Description 消费者-主题交换器
 * @createTime 2020年06月25日 20:18
 */
@Component
@RabbitListener(queues = "h.info.email")
public class TopicEmailMessageReceiver {

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

package com.h.rabbitmq.springboot.topic;

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

/**
 * @author h
 * @Description TODO
 * @createTime 2020年06月25日 20:28
 */
@Component
@RabbitListener(queues = "h.info.user")
public class TopicUserMessageReceiver {

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

1.7 广播交换器，生产者 和 消费者

1.7.1 生产者

package com.h.rabbitmq.springboot.fanout;

import com.h.rabbitmq.springboot.RmConst;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

/**
 * @author h
 * @Description TODO
 * @createTime 2020年06月25日 20:35
 */
@Component
public class FanoutSender {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    public void send(String message) {
        String sendMsg = message +"---"+ System.currentTimeMillis();;
        System.out.println("FanoutSender : " + sendMsg);
        rabbitTemplate.convertAndSend(RmConst.EXCHANGE_FANOUT, "", message);
    }
}

1.7.2 消费者

package com.h.rabbitmq.springboot.fanout;

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

/**
 * @author h
 * @Description 广播交换器
 *      队列的名称要与配置类 RabbitConfig 中声明的队列保持一致，否则启动会报错，找不到队列。
 * @createTime 2020年06月25日 20:42
 */
@Component
@RabbitListener(queues = "h.fanout.A")
public class FanoutReceiver {

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

2、RabbitMQ 异步解耦实战

2.1 场景：

订单系统 与 库存系统之间添加 RabbitMQ，达到解耦效果，不过是哪个系统出现故障也不会影响到另一个系统的正常运行。

2.2 RPC 实现：

2.3 RabbitMQ 实现：

• 发送方确认、失败者通知（确保消息能够到MQ）
• 消息持久化（交换器、队列、消息 都需要持久化）
• 确保消息一定能够被存库消费，手动应答
  

2.4 具体代码

2.4.1 生产者服务：

添加 maven 依赖：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.2.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<!--springboot集成rabbitmq-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

配置 rabbit 连接参数

server.port=8080
spring.application.name=springboot-rabbitmq
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
# 发送方确认
spring.rabbitmq.publisher-confirms=true
# 虚拟主机
spring.rabbitmq.virtual-host=/
