struts文件下载问题
ACTION中：public InputStream getTargetFile() throws Exception{
return ServletActionContext.getServletContext().getResourceAsStream("upload\\"+getDownloadFileName());
}
public String getDownloadFileName(){
String downFileName=ServletActionContext.getRequest().getParameter("name");
try{
downFileName=new String(downFileName.getBytes(),"ISO8859-1");
}catch(UnsupportedEncodingException e){
e.printStackTrace();
}
return downFileName;
}
怎么name得到的参数是中文就有问题呢，，，拔出异常

回复 楼主 fujinliang 的帖子
有跟楼主同样的问题。。。。本人用JSP写个下载，求高手帮帮忙<%@ page language="java" contentType="text/html; charset=GBK"
pageEncoding="GBK"%>
<%@ page import="java.io.*" %>
<%
request.setCharacterEncoding("GBK");
String tempFileName="1.txt";//文件名字
byte b[]=new byte[10240];
//建立文件
File fileLoad=new File(application.getRealPath("/Upload"),tempFileName);
response.setHeader("Content-disposition","attachment;filename="+tempFileName);
response.setContentType("application/x-msdownload");
long fileLength=fileLoad.length();
String length=String.valueOf(fileLength);
response.setHeader("Content_Length",length);
//读取文件并发送到客户端下载
OutputStream o=response.getOutputStream();
FileInputStream in=new FileInputStream(fileLoad);
int n=0;
while((n=in.read(b))!=-1){
o.write(b,0,n);
}
in.close();
o.close();
%>

为什么那个tempFileName是中文的时候就不能下载呢？

1楼：
downFileName=new String(downFileName.getBytes(),"gbk");
或者 downFileName=new String(downFileName.getBytes(),"gb2312");
downFileName=new String(downFileName.getBytes(),"ISO8859-1");这种只支持英语。
