图片水印使用方法：

 CiipFileResources ciipFileResourcesA = JSON.parseObject(ciipCertification.getCertificatesPhotoJsonA(),CiipFileResources.class);
            ciipFileResourcesA.setId(null);
            ciipFileResourcesA.setCreateDate(new Date());//创建时间
            ciipFileResourcesA.setFileResourceType(CiipFileResourceType.REALNAME_CERTIFICATE);//实名认证：证件照片
            //缩略图
            ciipFileResourcesA.setThumbnail(ciipFileResourcesA.getFileShowUrl() + WaterMarkUtils.thumbnail);
            //水印处理过图片
            ciipFileResourcesA.setWatermark(ciipFileResourcesA.getFileShowUrl() + WaterMarkUtils.addImageWaterMark());
            ciipFileResourcesService.save(ciipFileResourcesA);
