RabbitMQ 发送消息到队列（交换机不参与的那种）

1. 导包

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

2.在 application.yml 文件里编写配置信息

spring:
  rabbitmq:
    host: 192.168.88.130
    port: 5672
    virtual-host: /hmall
    username: hmall
    password: 123

2. Autowired

@Autowired
private RabbitTemplate rabbitTemplate;

3. 编写代码

@GetMapping("/mq01")
public void mq01(){
    String queueName = "simple.queue";
    String msg = "hello,amqp";
    rabbitTemplate.convertAndSend(queueName, msg);
}
