微信小程序--仿微信小程序朋友圈Pro(内容发布、点赞、评论、回复评论)

微信小程序–仿微信小程序朋友圈Pro(内容发布、点赞、评论、回复评论)

项目开源地址M朋友圈Pro 求个Star

项目背景

基于原来的开源项目微信小程序仿朋友圈功能开发（发布、点赞、评论等功能）的基础上，终于推陈出新了。

有一说一，这次界面好看多了。至于推陈出新的原因很简单🧐，接了个定制的项目，做完之后就把项目前端开源了。后续会延续原项目基础，保持前端和云开发代码的开源。

项目分析

这次项目完全1:1高仿微信小程序朋友圈，但是额外加了个发帖权限校验(可以去掉)，项目小程序端的整体思想如下所示。

数据库设计

1.发帖记录表m_circle_list

2.评论记录表m_comment_list

3.点赞记录表m_thumb_list

4.统一身份校验表uims

项目关键问题

如何即时刷新点赞和评论页面(即如何给对象数组中的元素赋值)

ilike(e) {
      let cid = e.currentTarget.dataset.idx;
      let index = e.currentTarget.dataset.index;
      let nickname = app.globalData.userInfo.nickName;
      let thumblist = `list[${index}].thumbPOList`;
      let likelist = `list[${index}].thumblist`;
      Router.UpThumbInfo(cid).then(res => {
        this.setData({
          [likelist]: this.data.list[index].thumblist + nickname,
        })
      })
}

如何简短的表示分页查询条件规则

wx.request({
   url: Config.SevDomain+'circlepart',
   method:'GET',
   data:{
       page:parseInt(skipstep/3) + parseInt(skipstep%3)
   },
   success:res=>{
          
   }
})

如何联查数据库中的三张表并封装返回数据

封装返回数据

public class CirclePartDto {
    private CirclePO circlePO;
    private List<CommentPO> commentPOList;
    private List<String> thumbPOList;

    public CirclePO getCirclePO() {
        return circlePO;
    }

    public void setCirclePO(CirclePO circlePO) {
        this.circlePO = circlePO;
    }

    public List<CommentPO> getCommentPOList() {
        return commentPOList;
    }

    public void setCommentPOList(List<CommentPO> commentPOList) {
        this.commentPOList = commentPOList;
    }

    public List<String> getThumbPOList() {
        return thumbPOList;
    }

    public void setThumbPOList(List<String> thumbPOList) {
        this.thumbPOList = thumbPOList;
    }
}

事务多表联查 JPA 核心@Transactional注解

@RestController
public class CirclePartService {
    @Autowired
    CircleDao circleDao;
    @Autowired
    CommentDao commentDao;
    @Autowired
    ThumbDao thumbDao;
    @Transactional
    @RequestMapping(value = "/circlepart")
    public List<CirclePartDto> GetCircleByLimit(@RequestParam("page") Integer page){
        Pageable pageable = PageRequest.of(page,3, Sort.by(Sort.Direction.DESC,"createtime"));
        List<CirclePartDto> circlePartDtoList = new ArrayList<>();
        // stream 转化为 list
        List<CirclePO> circlePOList = circleDao.findAll(pageable).get().collect(Collectors.toList());
        // 查询
        for (int i=0;i<circlePOList.size();i++){
            CirclePO circlePO = circlePOList.get(i);
            Integer id = circlePO.getId();
            CirclePartDto circlePartDto = new CirclePartDto();
            circlePartDto.setCirclePO(circlePO);
            List<CommentPO> commentPOList = commentDao.findByCircleidOrderByCreatetime(id);
            List<ThumbPO> thumbPOList = thumbDao.findByCircleid(id);
            List<String> nicknameList = new ArrayList<>();
            for(int j=0;j<thumbPOList.size();j++){
                nicknameList.add(thumbPOList.get(j).getNickname());
            }
            circlePartDto.setThumbPOList(nicknameList);
            circlePartDto.setCommentPOList(commentPOList);
            circlePartDtoList.add(circlePartDto);
        }
        return circlePartDtoList;
    }
}
