1、基本逻辑分析

1.1 文章投票功能模块需求

• 用户可以发表文章,发表时默认给自己的文章投了一票
• 用户在查看网站时可以按评分进行排列查看 （想到排序就是zset）
• 用户也可以按照文章发布时间进行排序 （想到排序就是zset）
• 为节约内存，一篇文章发表后，7天内可以投票,7天过后就不能再投票了 （这里就是加上过期时间）
• 为防止同一用户多次投票，用户只能给一篇文章投一次票（重复就想到set）

1.2 数据库设计

文章基本信息表 article

 

文章票数与分值表 vote_data

文章投票详表 vote_details

1.3 使用到的数据类型和相关指令

指令如下：

• HASH：hset  hincrBy  hgetAll   expire
• SET：sadd  smembers
• ZSET：zadd   zscore  zincrby  zrevrange

1.4 key设计思路

key的设计一般使用数据库名+主键,这样就能够保证key的唯一性

比如：set user:1 123

1.5、记录已投票用户，防重投

• set：无序不重复
• zset：有序不重复

防止重复首先就想到set，zset类型数据，由于没有排行等需求，使用更加简单的set就能满足需求

1.6 记录文章分数

由于涉及到分数的排行和文章发布时间的排行，首先想到的就是使用zset保存数据（默认分数从小到大升序排序）

1.7、Redis缓存设计实战

1.8、缓存数据变化

2、代码实现

2.1文章处理相关接口

/**
 *  RedisArticleService
 *  
 * @author: honry.guan
 * @date: 2021/4/12 17:36
 */
public interface RedisArticleService {
    /**
     * 文章发布,这里只是做个演示，一般存在数据库中
     *
     * @param title   标题
     * @param content 内容
     * @param link    链接
     * @param userId  用户ID
     * @return 文章的ID
     */
    String postArticle(String title, String content, String link, String userId);

    /**
     * 获取key所有数据
     *
     * @param key redis的key
     * @return 数据集
     */
    Map<String, String> hgetAll(String key);

    /**
     * 文章投票
     *
     * @param userId    用户id
     * @param articleId 文章id
     */
    void articleVote(String userId, String articleId);

    /**
     * 获取文章某个字段的值
     *
     * @param key   redis的key
     * @param votes 字段field
     * @return 返回值
     */
    String hget(String key, String votes);

    /**
     * 文章列表查询（分页）
     *
     * @param page key
     * @return redis查询结果
     */
    List<Map<String, String>> getArticles(int page, String order);
}

2.2 具体接口实现

代码key说明：

文章1的投票人，不能重复投，使用set：jedis.sadd("voted:1" , userId);

文章对象信息，使用hash保存：jedis.hmset(article, articleData);

分数排行，看着排行，就想到zset：jedis.zadd("score:info", now + Constants.VOTE_SCORE, article);

时间排行，看着排行，就想到zset：jedis.zadd("time:", now, article);

@Service
public class RedisArticleServiceImpl implements RedisArticleService {
