#### 1.1.1：分析&实现 ####

接收到前端传入的动态id，到数据库修改对应的动态点赞数量，返回动态信息处理到redis缓存中，用来解决点赞前端点赞图标，点了动态赞要一直显示高亮。

@GetMapping("/{id}/like")
        public ResponseEntity likemovement(@PathVariable("id") ObjectId id){
            Movement likemovement = movementService.likemovement(id, UserHolder.getUserId());
            return ResponseEntity.ok(likemovement.getLikeCount());
        }

public Movement likemovement(ObjectId id,Long userId) {
            Movement movement = movementApi.likemovement(id);
            //将当前用户的点赞状态存入redis中
            String key = "MOVEMENTS_INTERACT_KEY"+movement.getId();
            String hashKey = "MOVEMENTS_LIKE_HASHKEY" + userId;
            stringRedisTemplate.opsForHash().put(key,hashKey,"1");
            return movement;
        }

Movement likemovement(ObjectId id);

@Override
        public Movement likemovement(ObjectId id) {
            //通过动态id查询到该条动态
            Query query = new Query().addCriteria(Criteria.where("id").is(id));
            Movement movement = mongoTemplate.findOne(query, Movement.class);
            //得到点赞数量
            Integer likeCount = movement.getLikeCount();
            //修改数据库点赞数量
            Update update = new Update().set("likeCount", likeCount + 1);
            UpdateResult updateResult = mongoTemplate.updateFirst(query, update, Movement.class);
            return mongoTemplate.findOne(query,Movement.class);
        }

            return ResponseEntity.ok(dislikemovement.getLikeCount());
        }

public Movement dislikemovement(ObjectId id, Long userId) {
            Movement movement = movementApi.dislikemovement(id);
            //将当前用户的点赞状态存入redis中
            String key = "MOVEMENTS_INTERACT_KEY"+movement.getId();
            String hashKey = "MOVEMENTS_LIKE_HASHKEY" + userId;
            stringRedisTemplate.opsForHash().delete(key,hashKey);
            return movement;
        }

Movement dislikemovement(ObjectId id);

@Override
        public Movement dislikemovement(ObjectId id) {
            //通过动态id查询到该条动态
            Query query = new Query().addCriteria(Criteria.where("id").is(id));
            Movement movement = mongoTemplate.findOne(query, Movement.class);
            //得到点赞数量
            Integer likeCount = movement.getLikeCount();
            //修改数据库点赞数量
            Update update = new Update().set("likeCount", likeCount - 1);
            UpdateResult updateResult = mongoTemplate.updateFirst(query, update, Movement.class);
