问题遇到的现象和发生背景
使用idea打包springboot程序：提示 No auto configuration classes found in META-INF/spring.factories. If you are using a custom packaging, make sure that file is correct.错误
问题相关代码
经过排查，该问题一般会出现在整体打包模式(只生成一个jar包)。
方法一：使用链接打包模式(把依赖包抽提到jar包外部)。
方法二：这种错误是idea在整体打包时，包顺序错误导致的。
如下代码是我的一个artifact文件，使用该文件打包就会报错。

</artifact>
</component>
运行结果及报错内容
我的解答思路和尝试过的方法
修改修改artifact源码。路径为/.idea/artifacts/application.xml
将其中的所有spring的依赖包放到最后。再次打包，即可正常运行。
