1:根据id查询单条动态
1.1:接口分析
注意: 单条动态 和 查询评论列表 ,同时完成,app端才可以显示内容
1.2:流程分析
根据id查询对应动态详情信息,接收到前端传来的id信息,到数据库中查询指定的数据,将数据处理封装返回前端,这个功能需要和该动态的所有评论一起实现才能在探花app上显示页面。
1.3:代码实现
接收请求的app服务端
app-server服务:controller层
@GetMapping("/{id}")
public ResponseEntity findmovement(@PathVariable("id") ObjectId id){
MovementVo findmovement = movementService.findmovement(id);
System.out.println(findmovement);
return ResponseEntity.ok(findmovement);
}
app-server服务:service层
public MovementVo findmovement(ObjectId id) {
//处理评论
Movement movement = movementApi.findmovement(id);
UserInfo userInfo = userInfoApi.findUser(movement.getUserId());
MovementVo movementVo = new MovementVo(movement.getId().toString(),
userInfo.getId(),userInfo.getAvatar(),userInfo.getNickname(),userInfo.getGender(),Integer.valueOf(userInfo.getAge()),
userInfo.getTags().split(","),movement.getTextContent(),movement.getMedias(),"500米",movement.getCreated().toString()
,movement.getLikeCount(),movement.getCommentCount(),movement.getLoveCount(),0,0);
return movementVo;
}
接口模块:专门封装接口的模块
Movement findmovement(ObjectId id);
public UserInfo findUser(Long id);
db提供者服务:mysql
@Override
public UserInfo findUser(Long id) {
UserInfo userInfo = this.userInfoMapper.selectById(id);
return userInfo;
}
mongo提供者服务:mongo
@Override
public Movement findmovement(ObjectId id) {
Query query = new Query();
query.addCriteria(Criteria.where("id").is(id));
Movement one = mongoTemplate.findOne(query, Movement.class);
return one;
}
2:发布评论
2.1:接口分析
2.2:流程分析
接收到前端传入的发布动态参数,将图片信息上传到阿里云上面,将数据处理保存到数据库中。
