ClassPathXmlApplicationContext和FileSystemXmlApplicationContext的路径设置祥解

* 即：   对于ClassPathXmlApplicationContext（）， classpath: 前缀是不需要的，   默认就是指项目的classpath路径下面；

*                            如果要使用绝对路径，需要加上 file: 前缀表示这是绝对路径；

*    

*       对于FileSystemXmlApplicationContext（）， 默认表示的是两种：

*    1，没有盘符的是 项目工作路径， 即项目的根目录；

*    2，有盘符表示的是   文件绝对路径。

*   

*        如果要使用classpath路径， 需要前缀   classpath:       .
