* 单个文件上传
-
* @author Administrator
-
* 上传文件其实是上传了两份，
-
*
-
* 首先将上传的文件保存到 default.properties 文件中 struts.multipart.saveDir键指定的目录中
-
* 默认是空的
-
* 保存在 Tomcat 6.0\work\Catalina\localhost\struts2目录下以.tmp后缀名的文件
-
*
-
* 如果要在 struts.multipart.saveDir 指定目录， 则可以在 src文件夹下 建一个 struts.properties,
-
* 覆盖 default.properties 的某些键值
-
*
-
* 还有一份是 存放在自己设定的目录下
