启动 nacos

下载 nacos 2.5.x
【windows环境启动】startup.cmd -m standalone
创建app-demo配置，common配置（可选）

spring:
  application:
    name: app-demo
  config:
    import:
      - nacos:${spring.application.name}
      - nacos:common # 共享文件，在 nacos 建 common 配置。不需要可以去掉
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
        namespace: public
        group: DEFAULT_GROUP
      config:
        server-addr: localhost:8848
        namespace: public
        group: DEFAULT_GROUP
        file-extension: yaml      
        # common 配置，不需要可以去掉
        extension-configs:
          - data-id: common
            group: DEFAULT_GROUP
            refresh: true

Application类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
