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);
    }

@GetMapping("/{id}/dislike")
    public ResponseEntity dislikemovement(@PathVariable("id") ObjectId id){
        Movement dislikemovement = movementService.dislikemovement(id, UserHolder.getUserId());
        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);

        return mongoTemplate.findOne(query,Movement.class);
