好奇葩的打包之旅，最后在stack overflow上找到了解决办法，遇到问题，还是多去google吧，国内真不行，百度质量太低，一件很小的事，花了我1个多小时。。

下面说一下我遇到的奇葩问题：
1.常见的就是mainClass找不到嘛，或者不能将所有包都导入
2.jar包中的配置文件死活不生效（就这个搞了很久），明明jar包根目录配置文件在哪里好好的放着，死活不生效，现在也不知道问题出在哪0.0）
3.Reactive的某个Bean找不到（因为我的demo是用的webFlux+Security)
4.AutoConfiguration不生效（这个也是要吐槽一下的，说什么spring.factories文件找不到，我TM的，明明在jar包里面好好放着。。。）

以上这些问题都可以通过下面的打包方式来解决：
