   **问题描述**
     **问题1**
   按照文档来操作调试，网关的一切配置准备就绪后，启动网关服务时，SpringCloudGatewayConfiguration.scala 
抛出空指针问题，问题截图如下：

   另外查看源码时还有一个疑问，如下图

gatewayParsers、gatewayRouters变量是如何赋值的，我的理解是初始时为null,没有找到赋值的地方，故出现以上空指针问题，望解答，谢谢！
   **问题2**
   如下图：gatewayProperties无法取到yml配置文件的赋值（增加依赖可解决：javax.el-api、javax.el）

   **本地启动配置如下**
