IE6下文件下载不能直接打开，提示‘找不到....'
这是什么原因呢？
请看我的原始代码：

if(!StringUtils.isEmpty(name)){try{String disposition = "attachment;filename="+ new String(name.getBytes("gb2312"),"iso-8859-1")+ "."+suffix;response.addHeader("Content-disposition", disposition);response.addHeader("Content-Length", String.valueOf(attachFile.length()));in = FileUtils.openInputStream(attachFile);    ou = response.getOutputStream();IOUtils.copy(in,ou);}catch(Exception e){e.printStackTrace();}finally{IOUtils.closeQuietly(in);IOUtils.closeQuietly(ou);}}

只要加上

response.setHeader("Connection", "close");

就OK了 1 楼 hemin108 2012-06-29 还是不行 2 楼 从百草园到三味书屋 2012-07-08 hemin108 写道还是不行
那么兄弟，那你找到其他的解决方法了吗？我又遇到了这个问题，但是解决不了哦。 3 楼 hemin108 前天 我这样写ok了
public void writeFileToResponse(Object fileObj,
HttpServletResponse response, String fileName, String contentType) {
if (fileObj == null || response == null
|| !StringUtils.hasText(fileName)
|| !StringUtils.hasText(contentType)) {
logger.error("writeFileToResponse the params error");
return;
}
try {
InputStream is = null;
if (fileObj instanceof InputStream) {
is = (InputStream) fileObj;
} else if (fileObj instanceof File) {
is = new FileInputStream((File) fileObj);
} else if (fileObj instanceof byte[]) {
is = new ByteArrayInputStream((byte[]) fileObj);
} else {
throw new ControllerException(
"writeFileToResponse not support："
+ fileObj.getClass().getName());
}

xt 文件问题
if(contentType.equals("text/plain")){

}
response.reset();
