public class IndexController extends GenericForwardComposer {
    public void onDownfile() {
        try {
            String charset = "UTF-8";
            //服务器文件名
            String fileName = "Sip坐席通讯协议.txt";
            //编码后文件名
            String encodedName = null;
            encodedName = URLEncoder.encode(fileName,charset);
            //将空格替换为+号
            encodedName =encodedName.replace("%20","+");

            HttpServletRequest httpRequest =(HttpServletRequest) Executions.getCurrent().getNativeRequest();
            //解决ie6 bug 或者是火狐浏览器
            if (encodedName.length() > 150
                    ||Servlets.isGecko(httpRequest)
                    ||Servlets.isGecko3(httpRequest)) {
                encodedName = new String(fileName.getBytes(charset), "ISO8859-1");
            }
            Filedownload.save(new FileInputStream(ZkUtils.getRealPath("/" + fileName)),
                    "application/octet-stream", encodedName);
        } catch (Exception e) {
        }
    }
}

我直接修改了org.zkoss.web.servlet.http包底下的Https类的encodeFilename方法也可以解决这个问题.

private static String encodeFilename(String flnm) {
    String filename = Strings.escape(flnm, "\"") ;
    [color=red]try {
        filename =URLEncoder.encode(filename, "UTF-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }[/color]
    return '"' + filename+ '"';
}

private static String encodeFilename(String flnm) { String filename = Strings.escape(flnm, "\"") ; [color=red]try { filename =URLEncoder.encode(filename, "UTF-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); }[/color] return '"' + filename+ '"'; }

我用的是zk-5.0.5版本.

你这也是一种方式，我也留下我的一种处理方式吧：

Execution ex = Executions.getCurrent();
HttpServletRequest request = (HttpServletRequest) ex.getNativeRequest();
if (request.getHeader("User-Agent").indexOf("MSIE") != -1) {// ie
docFilename = URLEncoder.encode(docFilename, "UTF-8");
} else {// firefox
docFilename = MimeUtility.encodeText(docFilename, "GBK", "B");
}
