    import org.springframework.web.bind.annotation.RestController;
    
    @SpringBootApplication
    @RestController
    @NacosPropertySource(dataId = "nacos_test.yaml",groupId = "DEFAULT_GROUP",autoRefreshed = true)
    public class NacosdemoApplication { 
    
        @NacosValue(value = "${approval.app.appId:1762222222}",autoRefreshed = true)
        private String appId;
    
        @NacosValue(value = "${name:IT云清}",autoRefreshed = true)
        private String name;
    
        public static void main(String[] args) { 
            SpringApplication.run(NacosdemoApplication.class, args);
        }
    
        @GetMapping("test1")
        public String test1(String age){ 
            System.out.println(age+" : "+appId+" : "+name);
            return age+" : "+appId+" : "+name;
        }
