 nacos配置

nacos:
  # 配置中心
  config:
    server-addr: localhost:8848
    # 权限认证，nacos.core.auth.enabled=true 时需要添加
    username: nacos
    password: nacos
    file-extension: yaml
    # 设置配置文件所属命令空间
    namespace: e9232680-860c-4217-b312-75de46e374e9
    #服务注册
  discovery:
    username: nacos

    server-addr: localhost:8848
    # 服务注册命令空间
    namespace: e9232680-860c-4217-b312-75de46e374e9
    file-extension: yaml
    # 设置配置文件所属组
    group: DEFAULT_GROUP

 

 启动配置

@SpringBootApplication
@RestController
@NacosPropertySource(dataId = "demor.yml", autoRefreshed = true)
public class APPApplication {
    public static void main(String[] args) {
        SpringApplication.run(APPApplication.class, args);
        System.out.println("################### 启动成功 ##################");
    }
}

获取服务列表和配置文件 

    //获取服务列表
    @NacosInjected
    private NamingService namingService;
    //获取配置文件
    @NacosValue(value = "${ff.fg}", autoRefreshed = true)
    private String fg;
    @GetMapping("/nacos")
    public String nacos () throws IOException, NacosException {

        System.out.println(fg);
        System.out.println(namingService.getAllInstances("demor"));


        return "ok";
    }
