1、controller层代码：
/** * 手动发表评论 * * @param commentInfoVO 评论信息VO对象 * @return 处理结果 */ @PatchMapping("/") public Boolean publishComment(HttpServletRequest request, CommentInfoVO commentInfoVO, MultipartFile[] files) { try { // 为评论设置是否晒图 Integer showPictures = ShowPictures.NO; if (files != null && files.length > 0) { for (MultipartFile file : files) { if (file != null) { showPictures = ShowPictures.YES; break; } } } commentInfoVO.setShowPictures(showPictures); //保存评论信息 CommentInfoDTO commentInfoDTO = commentInfoVO.clone(CommentInfoDTO.class); commentInfoService.saveManualPublishedCommentInfo(commentInfoDTO); // 上传评论晒图图片 String appBasePath = request.getSession().getServletContext().getRealPath("/"); commentPictureService.saveCommentPictures(appBasePath, commentInfoDTO.getId(), files); // 更新评论统计信息 commentAggregateService.refreshCommentAggregate(commentInfoDTO); // 通知订单中心订单已经发表了评论 orderFacadeService.informPublishCommentEvent(commentInfoDTO.getOrderInfoId()); // 通知会员中心用户已经发表了评论 membershipFacadeService.informPublishCommentEvent( commentInfoDTO.getUserAccountId(), ShowPictures.YES.equals(showPictures)); } catch (Exception e) { logger.error("发表评论失败", e); return false; } return true; }
2、service层代码实现
/** * 保存评论晒图 * * @param appBasePath 当前应用的根路径 * @param commentInfoId 评论信息id * @param files 评论晒图 * @return 处理结果 */ @Override public Boolean saveCommentPictures(String appBasePath, Long commentInfoId, MultipartFile[] files) { //处理上传路径 if (CommentPictureUploadDirType.RELATIVE.equals(uploadDirType)) { uploadDirPath = appBasePath + uploadDirPath; } //将图片上传到指定目录去 try { // 如果上传目录不存在，则自动创建该目录 File uploadDir = new File(uploadDirPath); if (!uploadDir.exists()) { uploadDir.mkdir(); } for (MultipartFile file : files) { if (file == null) { continue; } // 如果目标文件路径已经存在，则删除目标文件 String targetFilePath = uploadDirPath + file.getOriginalFilename(); File targetFile = new File(targetFilePath); if (targetFile.exists()) { targetFile.delete(); } // 将上传上来的文件保存到指定的文件中去 file.transferTo(targetFile); String format = dateTimeFormatter.format(LocalDateTime.now()); // 将评论晒图信息保存到数据库中去 CommentPictureDO commentPictureDO = new CommentPictureDO(); commentPictureDO.setCommentPicturePath(targetFilePath); commentPictureDO.setCommentInfoId(commentInfoId); commentPictureDO.setGmtCreate(format); commentPictureDO.setGmtModified(format); commentPictureDAO.saveCommentPicture(commentPictureDO); } } catch (Exception e) { logger.error("保存图片失败", e); return false; } return true; }
3、配置文件
comment.picture.upload.dir.type=relative comment.picture.upload.dir=/upload/
