#### 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

![5743b7a97b574055abafe6584aadc736.png][]

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

![71718f7d2c4c4a88ac7a7ff111f44bb5.png][]

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 ####

            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;
        }

            List<Movement> movements = mongoTemplate.find(query, Movement.class);
