zhangbeiyuan-hw opened a new issue #1627: 静态页面直接部署到gateway-service，提示 root 
cannot start with '/'
URL: https://github.com/apache/servicecomb-java-chassis/issues/1627
 
 
   配置WEBAPP_ROOT的时候，试过绝对路径/usr/app/configs/static/ 和 相对路径./configs/static/ 
都不行，在window本地调试可以，部署到linux k8s上就不行了。
   
   配置如下：
   WEBAPP_ROOT=./configs/static/
   Java代码如下：
   ···java
       @Override
       public void init(Router router) {
           String regex = "/(.*)";
           String webappPath = InitConfig.getValue(InitConfig.WEBAPP_ROOT);
           if (webappPath == null || !new File(webappPath).exists()) {
               LOGGER.error("Start error, No webapp files. root={}", 
webappPath);
               return;
           }
   
           StaticHandler webpageHandler = StaticHandler.create();
           webpageHandler.setWebRoot(webappPath);
   
           LOGGER.info("server static web page for WEB_ROOT={}", webappPath);
           router.routeWithRegex(regex).failureHandler((context) -> {
               LOGGER.error("", context.failure());
           }).handler(webpageHandler);
       }
   ···
