Springcloud结合RabbitMq

1、添加maven pom依赖

<!--结合消息队列-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
    <version>2.0.6.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <version>2.0.6.RELEASE</version>
</dependency>

2、application.xml配置

spring:
#结合rabbitmq
  rabbitmq:
    host: 47.105.184.157
    port: 5672
    username: guest
    password: guest

3、定义Rabbitmq的配置类

package com.etc.website.configuration;

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

/**
 * 消息队列配置文件
 * @author ChenDang
 * @date 2020/1/22 0022
 */
@Configuration
public class RabbitConfiguration {

    /**
     * 创建test队列
     */
    public Queue test(){
        return  new Queue("test");
    }

}

消费者

package com.etc.website.mq;

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

/**
 * 消费者,@RabbitListener对test队列进行监听
 * @author ChenDang
 * @date 2020/1/22 0022
 */
@Component
@RabbitListener(queues = "test")
public class Receiver {

    /**
     * @RabbitHandler进行监听处理
     * @param hello
     */
    @RabbitHandler
    public void process(String hello){
        System.out.println("receive："+hello);
    }
}

生产者

package com.etc.website.mq;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.util.Date;

/**
 * 发送者
 * @author ChenDang
 * @date 2020/1/22 0022
 */
@Component
public class Sender {

    @Autowired
    private AmqpTemplate amqpTemplate;

    public void send(){
        String content = "hello"+new Date();
        System.out.println("send content:"+content);
        //生产者会向Queue=test的队列发送一条消息
        amqpTemplate.convertAndSend("test",content);
    }
}

 

编写测试接口

@GetMapping("/rabbitmq")
public String rabbitmq(){
   sender.send();
    return "消息队列测试";
}

浏览完get请求

http://localhost:8080/index/rabbitmq

控制台输出生产者和消费者的数据

springcloud集成rabbitmq成功
