篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了nacos服务消费者相关的知识，希望对你有一定的参考价值。
参考技术A 消费者跟提供者配置方式基本差不太多, 使用的时候提provider提供数据,而consumer调用provider,调用的方式有很多中,常用的有三种方式:然在Nacos工程下创建一个子工程命名其pom文件与nacos-provider相同

登录Nacos控制台，在服务列表选项卡中看到我们的两个应用，并可以对其进行简单的监控和管理。
浏览器中访问服务消费者的接口 http://127.0.0.1:9528/ 可以看到成功返回结果

运行NacosProviderApp后，可以在nacos的服务列表查看到生产的服务名

消费方也是暴露一个服务，也会在服务列表生产一个服务名
服务远程调用
http://localhost:56020/service
成功调用服务生产者的地址
网关配置
