文件上传-------------------(2)富文本文件上传

1.和上一篇的SpringMVC上传文件代码和工具相差无几，有的只是Controller最后调用的时候需要根据富文本上传文件的格式改一下就好

2.Controller

@RequestMapping("richtext_img_upload.do")
    @ResponseBody
    public Map richtextImgUpload(HttpSession session, @RequestParam(value = "upload_file",required = false) MultipartFile file, HttpServletRequest request, HttpServletResponse response) {
        Map resultMap = Maps.newHashMap();
        User user = (User) session.getAttribute(Const.CURRENT_USER);
        if (user == null) {
            resultMap.put("success", false);
            resultMap.put("msg", "请登录管理员");
            return resultMap;
        }
        //富文本中对于返回值有自己的要求,我们使用是simditor所以按照simditor的要求进行返回
//        {
//            "success": true/false,
//                "msg": "error message", # optional
//            "file_path": "[real file path]"
//        }
        if (iUserService.checkAdminRole(user).isSuccess()) {
            String path = request.getSession().getServletContext().getRealPath("upload");
            String targetFileName = iFileService.upload(file, path);
            if (StringUtils.isBlank(targetFileName)) {
                resultMap.put("success", false);
                resultMap.put("msg", "上传失败");
                return resultMap;
            }
            String url = PropertiesUtil.getProperty("ftp.server.http.prefix") + targetFileName;
            resultMap.put("success", true);
            resultMap.put("msg", "上传成功");
            resultMap.put("file_path", url);
            response.addHeader("Access-Control-Allow-Headers", "X-File-Name");
            return resultMap;
        } else {
            resultMap.put("success", false);
            resultMap.put("msg", "无权限操作");
            return resultMap;
        }
    }
