问题遇到的现象和发生背景
我的项目是一个API网关项目，使用的spring-cloud-gateway，之前使用的springboot2.2版本，并在项目中自定义了错误异常处理，其中使用到一个类ResourceProperties，但是当我升级到springboot2.7.1后，该类被移除了，但是有一个类WebProperties的内部静态类Resources好像是ResourceProperties的代替者，但是我使用的过程中总是报错，还没找到如何使用。
问题相关代码，请勿粘贴截图
就是如下两个类使用到了ResourceProperties，在springboot2.7.1缺失

运行结果及报错内容
我将ResourceProperties替换成了WebProperties，但是启动报错：

我的解答思路和尝试过的方法
我找到了WebProperties的内部类Resource可以作为替代者，但是不知道如何使用，简单的使用总是报错
我想要达到的结果
我想知道该如何使用WebProperties来代替我之前的ResourceProperties
