2. 消费者、生产者

2.1 消费者

package com.example.mq.consumer;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
/**
 * 消费者
 */
@Component
public class Receiver {
    // 处理消息
    @RabbitListener(queues ={"${mq.queue.name}"})
    public void process(String msg){
        System.out.println("receive:"+msg);
    }
}

2.2 生产者

package com.example.provider;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
/**
 * 生产者
 */
@Component
public class Sender {
    @Autowired
    private AmqpTemplate amqpTemplate;
    @Value("${mq.queue.name}")
    private String queueName;
    /**
     * 发送消息到队列
     * @param msg
     */
    public void send(String msg){
        amqpTemplate.convertAndSend(queueName,msg);
    }
}

2.3 测试

• 启动服务，消费者处于监听状态
• 调用send方法发送消息
