1.1：发布动态

1.1.1：接口分析

接口：http://192.168.136.160:3000/project/19/interface/api/154

1.1.2：流程分析

发布动态：动态发布存入动态表中，在朋友表中查找自己的朋友，在将动态id及相关信息标记自己信息，方便朋友登录时可查看好友动态发现朋友动态

1.1.2：代码实现

与前端交互的app-server模块

controller层实现

@PostMapping
    public ResponseEntity fabudongtai(@RequestParam("imageContent") List<MultipartFile> imageContent,PostUpdateVo postUpdateVo){
        movementService.fabudongtai(imageContent,postUpdateVo,UserHolder.getUserId(),UserHolder.getMobile());
        return ResponseEntity.ok(null);
    }

service层实现

public void fabudongtai(List<MultipartFile> imageContent, PostUpdateVo postUpdateVo, Long userId, String mobile) {
        for (MultipartFile multipartFile : imageContent) {
            String upload = ossTemplate.upload(multipartFile);
            System.out.println(upload);
            postUpdateVo.getImages().add(upload);
        }
        movementApi.fabudongtai(postUpdateVo,userId,mobile);
    }

统一封装接口的模块

void fabudongtai(PostUpdateVo postUpdateVo, Long userId, String mobile);

提供者模块(提供相关接口的实现)

mongo提供者：

@Override
    public void fabudongtai(PostUpdateVo postUpdateVo, Long userId, String mobile) {
        //保存动态到mongo动态表中
        Movement movement = new Movement();
        Long movement1 = idWorker.getNextId("movement");
        movement.setPid(movement1);
        movement.setUserId(userId);
        movement.setTextContent(postUpdateVo.getTextContent());
        movement.setMedias(postUpdateVo.getImages().toArray(new String[0]));
        movement.setState(0);
        movement.setLongitude(Double.valueOf(postUpdateVo.getLongitude()));
        movement.setLatitude(Double.valueOf(postUpdateVo.getLatitude()));
        movement.setLocationName(postUpdateVo.getLocation());
        movement.setCreated(new Date().getTime());
        //保存动态表
        Movement save = mongoTemplate.save(movement);

        //查询好友列表
        //构建条件
        Query query = new Query();
        Criteria criteria = Criteria.where("userId").is(userId);
        query.addCriteria(criteria);
        List<Friend> friends = mongoTemplate.find(query, Friend.class);

        //保存时间线数据
        for (Friend friend : friends) {
            MovementTimeline movementTimeline = new MovementTimeline(save.getCreated(),friend.getFriendId(),save.getId(),save.getUserId());
            mongoTemplate.save(movementTimeline);
        }
        //处理结束
    }

1.2：我的动态

1.2.1：接口分析

接口地址：http://192.168.136.160:3000/project/19/interface/api/142

1.2.2：流程分析

根据自己的id到数据库中找到动态所属的用户id一致即可。

1.2.3：代码实现

 与前端交互的app-server模块

controller层实现

@GetMapping("/all")
    public ResponseEntity findmovements(PublicPageVo publicPageVo){
        ResultList resultList = movementService.findmovements(UserHolder.getUserId(),publicPageVo);
        return ResponseEntity.ok(resultList);
    }

service层实现

public ResultList findmovements(Long userId, PublicPageVo publicPageVo) {
        ResultList findmovements = movementApi.findmovements(userId,publicPageVo);
        return findmovements;
    }

统一封装接口的模块

public ResultList findmovements(Long userid, PublicPageVo publicPageVo);

mongo提供者模块(提供相关接口的实现)

@Override
    public ResultList findmovements(Long userid, PublicPageVo publicPageVo) {

        //创建封装信息类
        ResultList resultList = new ResultList();
        Query query = new Query();
        //查询用户详情信息
        UserInfo userInfo = userInfoMapper.selectById(userid);

        Criteria criteria = Criteria.where("userId").is(userid);
        long count = mongoTemplate.count(query, Movement.class);
        query.addCriteria(criteria).skip((publicPageVo.getPage()-1)* publicPageVo.getPagesize()).limit(publicPageVo.getPagesize().intValue());

        query.with(Sort.by(Sort.Order.desc("created")));
        List<Movement> movements = mongoTemplate.find(query, Movement.class);

        ArrayList<MovementVo> movementVos = new ArrayList<>();


        for (Movement movement : movements) {
            //创建封装类
            MovementVo movementVo = new MovementVo(movement.getId().toString(),
                    userInfo.getId(),userInfo.getAvatar(),userInfo.getNickname(),userInfo.getGender(),userInfo.getAge(),
                    userInfo.getTags().split(","),movement.getTextContent(),movement.getMedias(),"",movement.getCreated().toString()
                    ,movement.getLikeCount(),movement.getCommentCount(),movement.getLoveCount(),0,0);

            movementVos.add(movementVo);
        }
        //设置列表
        resultList.setItems(movementVos);
        //设置当前页码
        resultList.setPage(publicPageVo.getPage().intValue());
        //设置总记录数
        resultList.setCounts((int) count);
        //设置页大小
        resultList.setPagesize(publicPageVo.getPagesize().intValue());
        //设置总页数
        resultList.setPages((int) (count%publicPageVo.getPagesize() == 0 ? count/ publicPageVo.getPagesize():(count/ publicPageVo.getPagesize())+1));

        return resultList;
    }
