使用 IDEA 中创建 SpringBoot + RabbitMQ 项目

RabbitMQ的安装请参考RabbitMQ - CentOS系统安装

创建2个项目

1.Comsumer项目的目录结构如下所示：

1.1.OrderReceiver：

import com.chanchifeng.mq.producer.entity.Order;
import com.rabbitmq.client.Channel;
import org.springframework.amqp.rabbit.annotation.*;
import org.springframework.amqp.support.AmqpHeaders;
import org.springframework.messaging.handler.annotation.Headers;
import org.springframework.messaging.handler.annotation.Payload;
import org.springframework.stereotype.Component;

import java.io.IOException;
import java.util.Map;

@Component
public class OrderReceiver {

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "order-queue",durable = "true"),
            exchange = @Exchange(name="order-exchange",durable = "true",type = "topic"),
            key = "order.*"
        )
    )
    @RabbitHandler
    public void onOrderMessage(@Payload Order order
            ,@Headers Map<String,Object> headers
            ,Channel channer) throws IOException {
        //消费者操作

        System.out.println("start   收到消息");

//        System.out.println("订单ID:" + order.getId());
        System.out.println("订单Name:" + order);

        //手动签收

        Long deliveryTag = (Long)headers.get(AmqpHeaders.DELIVERY_TAG);
        //ACK
        channer.basicAck(deliveryTag,false);

    }

}

1.2.Order:

import lombok.Data;

import java.io.Serializable;

@Data
public class Order implements Serializable {

    private int id;
    private String name;
    private String messageId;

}

1.3.ComsumerApplication:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ComsumerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ComsumerApplication.class, args);
    }

}

1.4.application.properties:

1.5.application.yml:

## springboot整合rabbitmq的基本配置

2.Producer项目的目录结构如下所示：

2.1.Order:

import lombok.Data;

import java.io.Serializable;

@Data
public class Order implements Serializable {

    private int id;
    private String name;
    private String messageId;

}

2.2.OrderService:

import com.chanchifeng.mq.producer.entity.Order;
import org.springframework.amqp.rabbit.connection.CorrelationData;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class OrderService {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    //发送消息方法调用: 构建自定义对象消息
    public void sendOrder(Order order) throws Exception {
        // 通过实现 ConfirmCallback 接口，消息发送到 Broker 后触发回调，确认消息是否到达 Broker 服务器，也就是只确认是否正确到达 Exchange 中
//        rabbitTemplate.setConfirmCallback(confirmCallback);
        //消息唯一ID
        CorrelationData correlationData = new CorrelationData();
        correlationData.setId(order.getMessageId());
        rabbitTemplate.convertAndSend("order-exchange", "order.ABC", order, correlationData);
    }

}

2.3.ProducerApplication:

@SpringBootApplication
public class ProducerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ProducerApplication.class, args);
    }

}

2.4.application.properties:

        Order order = new Order();
        order.setId(20190619);
        order.setName("测试订单2019-06-19");
        order.setMessageId(System.currentTimeMillis()+"$"+ UUID.randomUUID().toString());
        try {
            orderService.sendOrder(order);
        } catch (Exception e) {
            e.printStackTrace();
        }

3.测试的时候仅需要使用producer的ProducerApplicationTest中的测试例子即可，在此之前需要启动comsumer的项目，项目运行的效果如下图所示：

项目在Github中的SpringBoot-Sample/SpringBoot-Rabbit-Producer 和 SpringBoot-Sample/SpringBoot-Rabbit-Comsumer ：
