用smartUpload传文件的同时,传递参数的注意事项

用smartUpload传文件的同时,传递参数时,在获取参数时,

<input type="text" name="file_name"><br>
String name = smart.getRequest().getParameter("file_name") ;

参数名不能是filename或者是模糊匹配filename,否则取不到值,此情况在本人使用的版本中发现.

upload_1.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
