官方的源码好像不能用，就打开例子页面，从例子拿到几个js,见附件：


官方说:要想获得服务器在上传完成后，返回的信息，就使jquery.plupload.queue.js

                var uploader = $("#" + obj.divId).pluploadQueue();
                uploader.bind('FileUploaded', function (up, files, response) {
                    response//这个就是服务器返回的信息
                });

cakephp:

echo $this->Html->css("/js/plugins/plupload/js/jquery.ui.plupload/css/jquery.ui.plupload");
    echo $this->Html->css("/js/plugins/plupload/js/jquery.plupload.queue/css/jquery.plupload.queue");
    echo $this->Html->script("plugins/plupload/browserplus-min");
    echo $this->Html->script("plugins/plupload/plupload.full");
    echo $this->Html->script("plugins/plupload/jquery.plupload.queue");
    echo $this->Html->script("plugins/plupload/js/i18n/zh_CN");

                        <div id="uploader">
                            <p>Your browser doesn't have Flash, Silverlight or HTML5 support.</p>
                        </div>

$("#uploader").pluploadQueue({
            // General settings
            runtimes : 'html5',
            url : "/Admin/upload",
            chunk_size : '1mb',
            unique_names : true,

            filters : {
                max_file_size : '10mb',
                mime_types: [
                    {title : "Image files", extensions : "jpg,gif,png"},
                    {title : "Zip files", extensions : "zip"}
                ]
            },

            // Resize images on clientside if we can
            resize : {width : 320, height : 240, quality : 90},
            flash_swf_url: '/js/plugins/upload/plupload.flash.swf',
            silverlight_xap_url: '/js/plugins/upload/plupload.silverlight.xap'
        });
        var uploader= $("#uploader").pluploadQueue();
        uploader.bind('FileUploaded', function (up, files, response) {
            alert($.toJSON(response));
        });

两个后台接受文件
Java:

@ResponseBody
    @RequestMapping(value = "/up", method = RequestMethod.POST)
    public Object uploadFile(HttpServletRequest request, HttpServletResponse response) throws Exception {

        /*Map map = new HashMap();
        Enumeration paramNames = request.getParameterNames();
        while (paramNames.hasMoreElements()) {
            String paramName = (String) paramNames.nextElement();

            String[] paramValues = request.getParameterValues(paramName);
            if (paramValues.length == 1) {
                String paramValue = paramValues[0];
                if (paramValue.length() != 0) {
                    System.out.println("参数：" + paramName + "=" + paramValue);
                    map.put(paramName, paramValue);
                }
            }
        }*/


        Map<String, Object> result = new HashMap<String, Object>();
        Map<String, Object> fileInfo = new HashMap<String, Object>();
        Map<String, Object> feedback = new HashMap<String, Object>();
        MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
        MultipartFile file = multipartRequest.getFile("file");
        String filename = request.getParameter("name");
        File outFile = null;
        FileOutputStream fos = null;
        // 获得输入流：
        try {
            byte[] b = file.getBytes();
            outFile = Directory.createTemplate();
            fileInfo.put("clientFileName", filename);
            log.debug(outFile.getName() + ":" + EncDecUtils.encodeBase64(outFile.getName()));
            fileInfo.put("serverFileName", EncDecUtils.encodeBase64(outFile.getName()));
            result.put("fileInfo", fileInfo);

            fos = new FileOutputStream(outFile);
            fos.write(b);
            log.debug("上传文件成功,名字:{},{}", new Object[]{filename, outFile.getAbsoluteFile()});
        } catch (IOException e) {
            feedback.put("message", "上传出现错误");
            feedback.put("success", false);
            result.put("feedback", feedback);
            result.put("serverStatus", "500");
            //log.debug(JSONUtils.bean2str(result));
            log.debug("上传出现异常:{}" + e);
            return result;
        } finally {
            if (fos != null) fos.close();
        }
        feedback.put("message", "上传成功.");
        feedback.put("success", true);
        result.put("feedback", feedback);
        result.put("serverStatus", "200");
        log.debug(JSONUtils.bean2str(result));
        return result;

    }
