namespace设计真实一个奇特的东西。用spring-cloud-starter-alibaba-nacos-config测试的时候，JAVA代码里设置namespace必须使用那一串类似UUID的值，直接写英文名称一直获取不到值（public namespace除外），这个问题折腾了我好几天；网上的资料要么是写的不全，要么是胡编乱造；
真不知道这种设计意欲何为
启动类：
@SpringBootApplication
public class NacosMain {
public static void main(String[] args) {
SpringApplication.run(NacosMain.class ,args);
}
}Controller类
@RestController
@RefreshScope
public class NacosController {
@Value("${uu:}")
private String name;
@GetMapping("/hello")
public String info(){
// System.out.println(name);
return name;
}
}application.yaml

@Value("verify.qr_url")
privite String url;震惊！取不到值！
为啥呢？难道是用的nacos的原因，百度一下，还是没办法解决，那我试试拿其他配置，结果，拿到了！
那就可以断定，不是nacos的原因，那是啥原因呢
verify-url: xxxxxx
拿到了！
ok，解决了，就是我命名不规范，说不定人家naocs不认你这个，问我为啥这么确定是nacos不认，因为我直接写在本地application.yml里是可以读取到的。
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
