1.1：动态点赞

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);

    @Overridepublic 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);}

1.2：取消点赞

1.2.1：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，用来解决取消点赞前端点赞图标，取消动态赞不要显示高亮。

    @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);

    @Overridepublic 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);}

2：喜欢

2.1：动态喜欢

2.1.1：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喜欢数量，返回动态信息处理到redis缓存中，用来解决喜欢前端喜欢图标，点了动态喜欢要一直显示高亮。

    @GetMapping("/{id}/love")public ResponseEntity loveemovement(@PathVariable("id") ObjectId id){Movement loveemovement = movementService.loveemovement(id, UserHolder.getUserId());return ResponseEntity.ok(loveemovement.getLoveCount());}

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

Movement loveemovement(ObjectId id);

    @Overridepublic Movement loveemovement(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 loveCount = movement.getLoveCount();//修改数据库点赞数量Update update = new Update().set("loveCount", loveCount + 1);UpdateResult updateResult = mongoTemplate.updateFirst(query, update, Movement.class);return mongoTemplate.findOne(query,Movement.class);}

2.2：取消喜欢

2.2.2：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喜欢数量，返回动态信息处理到redis缓存中，用来解决喜欢前端喜欢图标，取消动态喜欢不显示高亮。

    @GetMapping("/{id}/unlove")public ResponseEntity unlovemovement(@PathVariable("id") ObjectId id){Movement unlovemovement = movementService.unlovemovement(id, UserHolder.getUserId());return ResponseEntity.ok(unlovemovement.getLoveCount());}

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

Movement unlovemovement(ObjectId id);
