用assembly打包一直报错：

网上看了一篇文章介绍说这是assembly打包spring项目的一个bug。参见（http://www.cnblogs.com/liqiu/p/4508848.html）
据说原因是spring的多个jar包中都含有spring.handlers和spring.schemas文件，而assembly只会把第一次遇到的文件打入jar包，后面遇到的都会skip掉。
解决方法就是放弃assembly，使用shade插件来打包.在shade的打包配制中指明spring.handlers和spring.schemas文件会以append方式加入进来，从而确保其他spring的jar中的这两个文件的信息不会被遗漏。
下面是一个非常简单的例子，只有四个文件的Maven工程，代码再附件内：
