代码

//不是IE浏览器
if (request.getHeader("User-Agent").toUpperCase().indexOf("MSIE") < 0){ 
	if(request.getHeader("User-Agent").toUpperCase().indexOf("EDGE")> 0){
		response.setHeader("Content-Disposition", "attachment; filename="+  URLEncoder.encode(gridFSDBFile.getFilename(), "UTF-8"));
	}else{
		response.setHeader("Content-Disposition", "attachment; filename="+  new String(gridFSDBFile.getFilename().getBytes("GBK"), "ISO8859-1"));
	}						
}else{
	response.setHeader("Content-Disposition", "attachment; filename="+ URLEncoder.encode(gridFSDBFile.getFilename(), "UTF-8"));//IE浏览器
}

应用

	@Override
	public void processDownGridFs(String id, HttpServletResponse response) {
		if(id != null && id.length() == 24) {
			GridFSDBFile gridFSDBFile = gridFsDao.find(id);
			if (gridFSDBFile != null) {
				try{
					OutputStream sos = response.getOutputStream();
					response.setContentType("application/octet-stream");					
					//不是IE浏览器
					if (request.getHeader("User-Agent").toUpperCase().indexOf("MSIE") < 0){ 
						if(request.getHeader("User-Agent").toUpperCase().indexOf("EDGE")> 0){						
							response.setHeader("Content-Disposition", "attachment; filename="+  URLEncoder.encode(gridFSDBFile.getFilename(), "UTF-8"));
						}else{
							response.setHeader("Content-Disposition", "attachment; filename="+  new String(gridFSDBFile.getFilename().getBytes("GBK"), "ISO8859-1"));
						}						
					}else{
						response.setHeader("Content-Disposition", "attachment; filename="+ URLEncoder.encode(gridFSDBFile.getFilename(), "UTF-8"));//IE浏览器
					} 			
					// 输出文件
					gridFSDBFile.writeTo(sos);
					sos.flush();
					sos.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
	}
