package com.master.rabbit;

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

/**

@Component
public class Receiver {

    @RabbitListener(queues = "rabbit-queue")
    @RabbitHandler
    public void process(String message) {
        System.out.println("Receiver : " + message);
    }

}

@RabbitListener 提供队列声明 官网介绍：https://docs.spring.io/spring-amqp/docs/2.0.4.RELEASE/reference/html/_reference.html#async-annotation-driven @RabbitHandler 不同类型的消息使用不同的方法来处理。

发送者

@Component
public class Sender {

    public void send() {
        String context = "hello " + new Date();
        System.out.println("Sender : " + context);
        this.rabbitTemplate.convertAndSend("rabbit-queue", context);
    }
