VUE+Java实现评论回复功能
背景
最近需要做一个多级评论的功能,技术路线:VUE(Element)+Java(SpringBoot)
效果
后台
SQL
Java
Controller
/** * 根据关联id获取评论信息 * @param relationId 关联id * @param type 类型 * @return: com.harvey.result.ResultSupport<java.lang.Object> * @date: 2020/12/10 14:37 */ @GetMapping("findList") public ResultSupport<Object> findList(@RequestParam("relationId") String relationId, @RequestParam("type") String type){ log.debug("接口[findList]的参数:relationId={}, type={}", relationId, type); ResultSupport<Object> result = ResultSupport.createMisResp(); try { List<Comment> commentList = commentService.findList(relationId, type); ResultSupportUtils.fillResultSupport(result, commentList); } catch (Exception e) { log.error("[findList]接口执行异常", e); ResultSupportUtils.fillError(result,"系统出现异常!"); } log.debug("接口[findList]的结果:result={}", result); return result; } /** * 保存评论 * @param comment 参数 * @return: com.tortoise.common.result.ResultSupport<java.lang.Object> * @date: 2020/12/10 14:37 */ @PostMapping("save") public ResultSupport<Object> save(@RequestBody Comment comment, HttpServletRequest request){ log.debug("接口[save]的参数:comment={}", comment); ResultSupport<Object> result = ResultSupport.createMisResp(); String token = request.getHeader("authorization"); if (StrUtil.isEmpty(token)) { result.setSuccess(false); result.setMessage("token无效!"); return result; } if (BeanUtil.isEmpty(comment)){ result.setSuccess(false); result.setMessage("参数无效!"); return result; } try { commentService.save(comment, token); } catch (Exception e) { log.error("[save]接口执行异常", e); ResultSupportUtils.fillError(result,"系统出现异常!"); } log.debug("接口[save]的结果:result={}", result); return result; }
Service
/** * 根据关联id获取绩效信息 */ public List<Comment> findList(String relationId, String type) { return commentMapper.findList(relationId, type); } /** * 保存评论 * @param comment 参数 * @param token 用户token * @return: * @date: 2020/12/10 14:37 */ @Transactional(rollbackFor = Exception.class) public void save(Comment comment, String token) { SysUser user = UserUtils.getUser(token); comment.preInsert(user.getId()); comment.setDelFlag("0"); commentMapper.save(comment); }
Mapper
/** * 根据关联id获取绩效信息 */ List<Comment> findList(@Param("relationId") String relationId, @Param("type") String type); /** * 根据id获取子评论内容 */ List<Comment> selectByParentId(@Param("parentId") String parentId); /** * 保存评论 */ void save(Comment comment);

前端
把评论抽成组件,方便其他模块引用

其他模块引用该评论组件
<template> <Comment :relationId="kpiPerformance.id" :commentType="'1'" :drawer="isComment" @commentClose="commentClick('0')" ></Comment> </template> <script> import Comment from "@/components/Comment"; export default { components: { Comment } } </script>
