#### 1.1.2：流程分析 ####

展示：如图信息

通过id到黑名单表中查询所对应的黑名单中人员信息，并分页，封装返回前端

#### 1.1.2：代码实现 ####

与前端交互的app-server模块

controller层实现

@GetMapping("/blacklist")
        public ResponseEntity findblacklist(BlackListVo blackListVo){
            System.out.println(blackListVo);
            ResultList findblacklist = userService.findblacklist(blackListVo,UserHolder.getUserId());
            return ResponseEntity.ok(findblacklist);
        }

service层实现

public ResultList findblacklist(BlackListVo blackListVo, Long userId) {
            ResultList findblacklist = userApi.findblacklist(blackListVo,userId);
            return findblacklist;
        }

统一封装接口的模块

ResultList findblacklist(BlackListVo blackListVo, Long userId);

提供者模块(提供相关接口的实现)

@Override
        public ResultList findblacklist(BlackListVo blackListVo, Long userId) {
            QueryWrapper<BlackList> blackListQueryWrapper = new QueryWrapper<>();
            blackListQueryWrapper.eq("user_id",userId);
            Page<BlackList> blackListPage = new Page<>(blackListVo.getPage(), blackListVo.getPagesize());
            Page<BlackList> blackListPage1 = blackMapper.selectPage(blackListPage, blackListQueryWrapper);
    
    //        //处理起始的索引
    //        List<BlackList> allBlack = blackMapper.findAllBlack(blackListVo.getPage() - 1, blackListVo.getPagesize());
            ResultList resultList = new ResultList();
            //设置页大小
            resultList.setPagesize(Math.toIntExact(blackListPage1.getSize()));
            //设置总记录数
            resultList.setCounts(Math.toIntExact(blackListPage1.getTotal()));
            //处理当前页
            resultList.setPage(Math.toIntExact(blackListPage1.getCurrent()));
            //处理总页数
            resultList.setPages(Math.toIntExact(blackListPage1.getPages()));
    
            for (BlackList record : blackListPage1.getRecords()) {
                UserInfo userInfo = userInfoMapper.selectById(record.getBlackUserId());
                if (userInfo != null){
                    record.setAvatar(userInfo.getAvatar());
                    record.setNickname(userInfo.getNickname());
                    record.setGender(userInfo.getGender());
                    record.setAge(userInfo.getAge());
                }
            }
            resultList.setItems(blackListPage1.getRecords().toArray());
            return resultList;
        }
