blog例子已经可以运行通过，自己重建一个工程却跑不通
http://www.jfinal.com/feedback/6252 这个贴子我也看了，问题还是没有解决。
我的web文件夹目录是 “web” ,
修正方法调用 JFinal.start("web", 80, "/");
可以依然还是无法调用到 configRoute 、configConstant 方法，感觉是配置不对，但不清楚是该配置哪？ 求指导一下。

com.demo.common.DemoConfig 代码如下：

public class IndexController extends Controller {

IDE 为 IntelliJ IDFEA 2019 ,JFinal 4.3 , jetty 启用
根据提示，应该是程序根本就没有调用 com.demo.common.DemoConfig , 不清楚是什么地方没配置对？ 希望专家给予指导，谢谢，
