中文文件可以下载，但是文件名不对，有乱码。

[appow]

String filename="例子.doc";
ServletOutputStream os = response.getOutputStream();
byte[] buffer = new byte[16 * 1024];
int readSize = 0;
response.setContentType("APPLICATION/OCTET-STREAM");
response.setHeader("Content-Disposition","attachment; filename=\"" + filename + "\"");
java.io.FileInputStream fileInputStream = new java.io.FileInputStream("d:/"+filename);
try {
while ((readSize = is.read(buffer))!=-1) {
os.write(buffer, 0, readSize);
}
response.flushBuffer();
} catch (Exception e) {
System.err.println(e.toString());
}

[AllError]

response.reset();
//response.setContentType("APPLICATION/OCTET-STREAM");
response.setContentType("bin");
response.setHeader("Content-Disposition",
"attachment; filename=\"" + filename + "\"");
System.out.println("response");

// 打开指定文件的流信息
java.io.FileInputStream fileInputStream =
new java.io.FileInputStream(filepath + filedir+ "\\" + filename);

// 写出流信息
int i;
while ((i=fileInputStream.read()) != -1) {
out.write(i);
}
fileInputStream.close();
out.close();

response.setHeader("Content-Disposition","attachment; filename=\"" + filename + "\"");
--->
response.setHeader("Content-Disposition", "attachment; filename="+new String(filename.getBytes(),"iso8859-1"));

对文件名进行编码转换~~~！

实在不行,参考

相应的改成了：
response.setHeader("Content-Disposition", "attachment; filename="+new String(filename.getBytes(),"iso8859-1"));

但是只有第一个汉字能正常显示，其它都是乱码！！！！！！！

[Hodex]

filename = new String(filename.getBytes("8859_1"));

[eternalee]

filename = new String(filename.getBytes("iso8859-1"),"GBK");

我是用时间戳做中文文件名问题的，不知道楼主需要否？[e-mail]

[Philzzf]

你是不是用了APACHE和tomcat整合？

[appow]

时间戳做中文文件名是怎么个思路，能否介绍一下？

没有用apache，只用tomcat3.3

[appow]

filename = new String(filename.getBytes("iso8859-1"),"GBK"); //试了，根本不好用

filename = new String(filename.getBytes("8859_1"));//当只有2个或少于2个汉字时，好用，大于2个汉字时全为乱码！！！

[eternalee]

res.setHeader("Content-Language","zh-CN");
req.setCharacterEncoding("GBK");

String filename="例子.doc";
ServletOutputStream os = response.getOutputStream();
byte[] buffer = new byte[16 * 1024];
int readSize = 0;
// ##########################################
//在这里做了修改，加入 charset=gb2312
response.setContentType("APPLICATION/OCTET-STREAM; charset=gb2312");
// ##########################################

response.setHeader("Content-Disposition","attachment; filename=\"" + filename + "\"");
java.io.FileInputStream fileInputStream = new java.io.FileInputStream("d:/"+filename);
try {
while ((readSize = is.read(buffer))!=-1) {
os.write(buffer, 0, readSize);
}
response.flushBuffer();
} catch (Exception e) {
System.err.println(e.toString());
}

[appow]

按照楼上的去编码，还是只能显示2个汉字，其它全不能显示了

把你的IE properties中的“始终用UTF-8方式传输”选项不选
