百度编辑器上传文件

百度编辑器前端接受的对象（前端要求的）

public class ImageVo implements Serializable {
    private static final long serialVersionUID = -3699242044954063640L;

    private String original = "";
    private int size = 0;
    private String state = "ERROR";
    private String title = "";
    private String type = "";
    private String url = "";
}

controller（需要注意的是请求的转换）

public ImageVo init(HttpServletRequest request, HttpServletResponse response) {
        try {
            CommonsMultipartResolver multipartResolver=new CommonsMultipartResolver(
                    request.getSession().getServletContext());
            if(multipartResolver.isMultipart(request)){
                MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest)request;
                Map<String, MultipartFile> fileMap = multiRequest.getFileMap();
                MultipartFile file = fileMap.get("upfile");
                //返回原来在客户端的文件系统的文件名
                String fileRealName = file.getOriginalFilename();

                int pointIndex = fileRealName.lastIndexOf(".");//点号的位置
                String fileSuffix = fileRealName.substring(pointIndex);//截取文件后缀

                String uuid = UUID.randomUUID().toString();

                Date d = new Date();
                SimpleDateFormat formatYear = new SimpleDateFormat("yyyy");
                SimpleDateFormat formatMonthDay = new SimpleDateFormat("MMdd");
                String year = formatYear.format(d);
                String monthDay = formatMonthDay.format(d);
                String imgStr = "/" + "img" + "/" + year + "/" + monthDay + "/" + uuid + fileSuffix;

                ImageVo imageVo = new ImageVo();
                File toFile = multipartFileToFile(file);
                if (toFile == null){
                    return new ImageVo();
                }
                UpYun upYun = new UpYun();
                try {
                    // 图片上传到upyun
                    boolean writeFile = upYun.writeFile(imgStr, toFile);
                    if (writeFile) {
                        imageVo.setOriginal(fileRealName);
                        imageVo.setState("SUCCESS");
                        imageVo.setType(fileSuffix);
                        imageVo.setTitle(uuid  + fileSuffix);
                        String url = "http://img.hotyq.com" + imgStr;
                        imageVo.setUrl(url);
                        return imageVo;
                    } else {
                        log.error("TDCode--generateTDCodeImage--upyun upload fail");
                        return new ImageVo();
                    }
                } catch (IOException e) {
                    log.error("TDCode--generateTDCodeImage--upyun upload fail:", e);
                    return new ImageVo();
                } finally {
                    toFile.delete();
                }
            }else {
                return new ImageVo();
            }

        } catch (Exception e) {
            // TODO Auto-generated catch block
            log.error("admin--UploadController-init--", e);
            return new ImageVo();
        }
    } 

文件格式转换（MultipartFile转file）

public static File multipartFileToFile(@RequestParam MultipartFile file) throws Exception {
        File toFile = null;
        if (file.equals("") || file.getSize() <= 0) {
            file = null;
            return  null;
        } else {
            InputStream ins = null;
            ins = file.getInputStream();
            toFile = new File(file.getOriginalFilename());
            inputStreamToFile(ins, toFile);
            ins.close();
            return toFile;
        }
    }

    public static void inputStreamToFile(InputStream ins, File file) {
        try {
            OutputStream os = new FileOutputStream(file);
            int bytesRead = 0;
            byte[] buffer = new byte[8192];
            while ((bytesRead = ins.read(buffer, 0, 8192)) != -1) {
                os.write(buffer, 0, bytesRead);
            }
            os.close();
            ins.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
