根本原因：没有依赖

问题过程

项目启动成功之后的截图

可以看到nacos只有网关，并没有flight-query这个服务

<nacos.discovery.version>2.2.3.RELEASE</nacos.discovery.version>     
   <!--nacos服务注册依赖-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>

加上这个以来以后，然后重新启动

可以看到一句

说明nacos已经注册了
