ClassNotFound找不到 redis.clients.jedis.JedisShardInfo

jedis升级到4.0版本时启动出现异常

原因：

新版本中ShardedJedisPool、Sharded、ShardedJedis、BinaryShardedJedis、ShardInfo、JedisShardInfo 类已被移除

官方说明

解决办法

回退到3.9.0

<dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>3.9.0</version>
</dependency>

Jedis 4建议使用JedisSharding替换ShardedJedisPool

Jedis 5开始，没有推荐的方法。完整的 Sharding/Sharded 功能已被弃用。
