Answer 1

String fileUrl="F:/MP3/蝴蝶泉边.wma";
FileInputStream fis = new FileInputStream(fileUrl);
OutputStream os = response.getOutputStream();
String fileName = fileUrl.substring(fileUrl.lastIndexOf("/")+1);
String fileNameEncoder = URLEncoder.encode(fileName, "utf-8");   //设置编码
response.setHeader("Content-disposition", "attachment; filename="
+ fileNameEncoder);
int temp = 0;
while ((temp = fis.read()) != -1) {
os.write(temp);
}

Answer 2

String fileName="测试.doc";         基本上把这句改成:String fileName("测试.doc","utf-8");即可

Answer 3

.......
       String path="E:\\测试.doc";
       String fileName="测试.doc";
       String disFileName = new String(fileName.getBytes("GBK"),"ISO8859_1");
       File file = new File(path);
       response.setCharacterEncoding("GBK");
       response.setContentType("application/x-msdownload");
       response.setContentLength( (int) file.length());
       response.setHeader("Content-Disposition", "attachment;filename="+disFileName);
.......

Answer 4

.....
public void doGet(HttpServletRequest request, HttpServletResponse response) throws
            ServletException, IOException {        //word要这么写的
        response.setContentType("application/msword;charset=gb2312");        String path="E:\\测试.doc";
        String fileName="测试.doc";        //显示中文文件名
        response.setHeader("Content-disposition","attachment; filename="

                  +new String( fileName.getBytes("GBK"), "ISO8859_1" ));        FileInputStream fis = new FileInputStream(file);
        BufferedInputStream fbis = new BufferedInputStream(fis);
        byte abyte0[] = new byte[1024];
        int k = 0;

swoky() 谢谢你 你的方法我测试了可以的 能再问你 只有word 文件特殊要加msword这个吗？
还是别的类型的文件也要加相应的 东西
