与前端交互的app-server模块

[controller层][controller]实现

@GetMapping("/recommendation")
        public ResponseEntity findAllrecommendation(RecommendPageVo recommendPageVo){
            ResultList allrecommendation = recommendService.findAllrecommendation(recommendPageVo, UserHolder.getUserId());
            return ResponseEntity.ok(allrecommendation);
        }

service层实现

@DubboReference
        private RecommendUserApi recommendUserApi;
        @DubboReference
        private UserInfoApi userInfoApi;
    
    
    public ResultList findAllrecommendation(RecommendPageVo recommendPageVo, Long userId) {

统一封装接口的模块

/**

    public interface RecommendUserApi {

        UserInfoVo findtodayBest(Long userId);
    
        UserInfoVo findUserInfo(Long id, Long userId);
    }

mongo提供者模块(提供相关接口的实现)

@Override

            Criteria criteria = Criteria.where("toUserId").is(userId);
            //查询总数
            Query query = new Query(criteria);
            long count = mongoTemplate.count(query, RecommendUser.class);
    
            //查询当前页的数据列表
            Query querylimit = new Query(criteria).limit(recommendPageVo.getPagesize()).skip((recommendPageVo.getPage() - 1)*recommendPageVo.getPagesize()).with(Sort.by(Sort.Order.desc("score")));
    
            List<RecommendUser> recommendUserList = mongoTemplate.find(querylimit, RecommendUser.class);
    
            ResultList resultList = new ResultList<>();
    
            resultList.setItems(recommendUserList);
            //设置列表
            //设置当前页码
            resultList.setPage(recommendPageVo.getPage());
            //设置总记录数
            resultList.setCounts((int) count);
            //设置页大小
            resultList.setPagesize(recommendPageVo.getPagesize());
            //设置总页数
            resultList.setPages((int) (count/recommendPageVo.getPagesize()));

缘分值是根据平台算法推算出的缘分值得分，将用户的缘分值存放到mongodb数据库中，这里通过当前登录用户的id，在系统中找到该用户的所有推荐用户，将推荐用户的缘分值进行降序找到最高缘分值用户，进行展示今日佳人。
