RabbitMQ 与springboot 最简单的集成

1.安装参考：https://blog.youkuaiyun.com/weixin_41004350/article/details/83046842

 注意：RabbiMq 和 Erlang 的版本兼容，官网：https://www.rabbitmq.com/which-erlang.html

2.SpringBoot整合

  springBoot和rabbitMQ已经有很好的的集成了，使用amqp

  maven依赖

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

yml配置

spring:
  application:
    name: RabbitMQ_Demo
  rabbitmq:
    host: 111.xxx.xxx.175
    port: 5672
    username: guest
    password: guest

创建消息队列(名称为hello的queue)

    //  import org.springframework.amqp.core.Queue;
    @Bean
    public Queue helloQueue(){
        return new Queue("hello");
    }

配置消息消费者

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

/**
 * @author jie
 * @date 2020/7/22 15:00
 */
@Component
@RabbitListener(queues = "hello")
public class RabbitMQConsumer {

    @RabbitHandler
    public void onMessage(String hello){
        System.out.println("收到消息 :"+hello);
    }
}

使用AmqpTemplate 向hello队列发送消息

@RequestMapping("api/v1/pro/proFunds")
public class ProFundsRest  {

    @Autowired
    private AmqpTemplate amqpTemplate;

    @GetMapping("send/{msg}")
    public InvokeResult send(@PathVariable("msg") String msg) {
        amqpTemplate.convertAndSend("hello",msg);
        return InvokeResult.success();
    }
}
