JFinal框架使用undertow嵌入式web服务器打jar包运行

我的集成示例：https://gitee.com/a_seagull/jfinal-common

jfinal官方示例参考：https://jfinal.com/download/now?file=jfinal_demo_for_maven-5.0.0.zip

集成时可能出现如下问题：

maven-shade-plugin - Cannot find 'resource' in class org.apache.maven.plugins.shade.resource.ManifestResourceTransformer

<!--  下面的配置支持排除指定文件打包到 jar 之中，可以用于排除需要修改的配置文件以便于在外部的 config 目录下的同名配置文件生效，建议使用 Prop.appendIfExists(xxx_pro.txt) 在外部放一个非同名配置来覆盖开发环境的配置
