spring mvc import resource路径问题【最简单的却也是最致命的】

某厂面试归来，发现自己落伍了！>>>

在import resource 路径中有两种写法

一种classpath，一种classpath*

那么这两种有什么区别呢？

1.**classpath:**只会到你的class路径中查找找文件；

2.**calsspath*:**不仅包含class路径，还包括jar文件中(class路径)进行查找，***classpath*:***对于多module的项目比较重要

但往往我们导入一个新的项目设置好路径后，还会报出Cannot resolve file 'applicationContext.xml'

运行localhost:8080时，会报出：

检查一阵路径，发现没有任何问题。其实这个问题是一个几乎可以认为是一个不应该迷惑着我们的问题，也正如当局者迷，最简单的确实最让我们犯错误的。

resources文件属性是否设置了

点击后：正确的样子

这样路径就不会出错了。
