这里我按照参考（1）文章的步骤操作，到了build项目这一步时报错：

解决方法参考：
https://blog.csdn.net/bskfnvjtlyzmv867/article/details/81171802
即这个主要是Kotlin插件的版本问题，解决方案是更新新版本的Kotlin插件：
https://www.jianshu.com/p/7c625599c1c9
然后重新引入的spring-cglib-repack和spring-objenesis-repack的jar包需要先自行下载，然而有更好的办法：
https://blog.csdn.net/yjteilz/article/details/53906368
解决这两个包的缺失问题后reimport一下，然后build。
这次又有新的错误：
Error:(19, 49) java: 找不到符号
符号: 类 AnnotationBeanConfigurerAspect
位置: 程序包 org.springframework.beans.factory.aspectj
。。。
解决方法参考：https://jira.spring.io/browse/SPR-12103
然而上面的链接中没有明确的解决方法，参考下面这个：
https://blog.csdn.net/qq_33240946/article/details/80433192
即unload aspects包，然后如果自己的demo用到这个包就在pom文件引入aspects和aop。
unload步骤参考：http://wiki.jikexueyuan.com/project/intellij-idea-tutorial/settings-introduce-4.html
再build，这次又轮到oxm模块报错，需要参考链接（2）的文章。
二、SpringBoot
解压SpringBoot源码压缩包的过程中会报错：文件夹路径过长
别用WinRAR，换一个解压软件（例如7-zip），但也不行，所以只能采用git clone的方式把源码下载下来。
