动机

抖音的评论只有按照点赞数降序，没有按照回复数降序。

在这里插入图片描述
点击“点赞”，点赞数+1.点击“回复”，回复数+1.
排序方式提供了两种：点赞数降序和回复数降序。

页面中用到了字典CommentOrder
在这里插入图片描述

后端代码

/*** 点赞*/@RequiresPermissions("comments:comments:edit")@RequestMapping(value = "delete")@ResponseBodypublic String delete(Comments comments) {//commentsService.delete(comments);Comments oldComment = commentsService.get(comments.getId());oldComment.setGoodNum(oldComment.getGoodNum()+1);commentsService.save(oldComment);return renderResult(Global.TRUE, text("点赞评论成功！"));}
/*** 回复*/@RequiresPermissions("comments:comments:edit")@RequestMapping(value = "reply")@ResponseBodypublic String reply(Comments comments) {Comments oldComment = commentsService.get(comments.getId());oldComment.setReplyNum(oldComment.getReplyNum()+1);commentsService.save(oldComment);return renderResult(Global.TRUE, text("回复评论成功！"));}
