SpringBoot-RabbitMq 简单实例

添加maven依赖：

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId></dependency>

创建队列:

package com.example.demo;import org.springframework.amqp.core.Queue;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;//创建队列@Configurationpublic class RabbitConfig {    @Bean    public Queue queue(){        return new Queue("hello");    }}

消息发送:

package com.example.demo;import org.springframework.amqp.rabbit.core.RabbitTemplate;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestControllerpublic class RabbitController {    @Autowired    RabbitTemplate rabbitTemplate;    @RequestMapping("/rm")    public void sendMsg(){        rabbitTemplate.convertAndSend("hello","你好你好hello");    }}

消息接收:

package com.example.demo;import org.springframework.amqp.rabbit.annotation.RabbitHandler;import org.springframework.stereotype.Component;//接收消息@[e-mail](queues = "hello")public class RabbitListener {    @RabbitHandler    public void getMsg(String msg){        System.out.println("接收到的消息:"+msg);    }}
