Spring Boot 3.1.4 使用的时候报错 java.lang.NoSuchMethodError: 'java.lang.Long redis.clients.jedis.Jedis.del(byte[])'

jedis 版本 4.3.2

有解决方案吗

我把它内嵌的jedis替换掉就好了

5.x的jedis好像只能改仓库代码了 https://github.com/ilaotan/shiro-redis/tree/jedis5

自己更新提升jedis的版本

[momocstar]

解决办法一：把RedisManager这个类进行覆盖重写，引入jedis编译自己的项目就行。
解决办法二：等作者修复。
解决办法三： 自己fork一分代码，自己修复。

以下演示最简单的修复方法一，其他有兴趣自己去搞。
