导入FileUpload和common-io的Jar包

注意：1、Struts2需要使用其他方法：struts2过滤时，会改变reqeust的类型，由HttpServletRequest变成MultiPartRequestWrapper

1、Test.jsp:

<form action="<%=basePath%>self/testFileUpload.do" method="post" enctype="multipart/form-data">
    	<input type="text" name="num">
    	<input name="img1" type="file" accept="image/gif,image/jpg,image/png,image/jpeg"/>
    	<input name="img2" type="file" accept="image/gif,image/jpg,image/png,image/jpeg"/>
    	<input type="submit" name="test">
    	<input type="reset" name="test1">
    </form>

@RequestMapping(value=http://www.mamicode.com/"/testFileUpload")>

SpringMVC使用FileUpload进行文件上传
