<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"

codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"

width="650" height="450" id="myMovieName">

<param name="movie" value="<%=_path%>/avatar.swf">

public @ResponseBody void uploadCompanyLogo(PrintWriter printWriter, HttpServletRequest request, HttpServletResponse response){

String userId = request.getSession().getAttribute("userId").toString();

String filename = "logo.jpg";

String logoPath = "D:/userLogo/" + userId;

String pic = request.getParameter("pic1"); //保存原图时，此时接收参数应是pic；尺寸1则是pic1，尺寸2则是pic2 。。。

File file = null;

File directory = null;

try {

directory = new File(logoPath);

if (!directory.exists()){

directory.mkdirs();

}

if(!pic.equals("")&&pic!=null){

file = new File(logoPath+"/"+filename);

FileOutputStream fout = null;

fout = new FileOutputStream(file);

fout.write(new BASE64Decoder().decodeBuffer(pic));

fout.close();

}

}

catch (IOException e) {

if (file.exists()){

file.delete();

}

}

printWriter.write("{\"status\":1,\"picUrl\":\""+filename+"\"}");

printWriter.flush();

printWriter.close();

}
