Spring Cache 异常：io.lettuce.core.RedisCommandExecutionException：“set”命令的参数数量错误

Question

我使用 Spring Boot 版本：2.1.4.RELEASE

当我spring.cache.redis.time-to-live=20000在application.yml文件中设置时，我得到了一个例外。当我想在redis缓存中添加TTL时应该怎么做？如何在带有 Redis 的 Spring Cache 中使用缓存过期？

我也面临着同样的问题。我使用的是redis 2.4.5版本，然后在阅读完这篇文章后，我升级到3.0.504并且它工作了（我的操作系统是windows）

正如本期所解释的：似乎在redis 2.6.0以下，我们无法设置生存时间（ttl） https://github.com/eiselems/ultimate-redis-boot/issues/1
