1.1：查询黑名单人员

1.1.1：接口地址

接口地址：http://192.168.136.160:3000/project/19/interface/api/286

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;
    }

1.2：移除黑名单人员

1.2.1：接口地址

接口地址：http://192.168.136.160:3000/project/19/interface/api/283

 

1.2.2：流程分析

 将数据库中对应的黑名单表通过前端传递的id值，进行移除响应的表数据。

1.2.3：代码实现

 与前端交互的app-server模块

controller层实现

    /**
     * 移除黑名单
     */
    @DeleteMapping("/blacklist/{uid}")
    public ResponseEntity deleteblack(@PathVariable("uid") Long uid){
        userService.deleteblack(uid);
        return ResponseEntity.ok(null);
    }

service层实现

    public void deleteblack(Long uid) {
        userApi.deleteblack(uid);
    }

统一封装接口的模块

    void deleteblack(Long uid);

提供者模块(提供相关接口的实现)

    @Override
    public void deleteblack(Long uid) {
        blackMapper.deleteById(uid);
    }
