我使用Spring Boot版本：2.1.4.RELEASE
当我在spring.cache.redis.time-to-live=20000文件中设置application.yml时，出现异常。我想在Redis缓存中添加TTL怎么办？
如何在Redis的Spring Cache中使用缓存过期？

答案 0 :(得分：0)
我也遇到了同样的问题。我使用的是 redis 2.4.5 版本，然后经过这篇文章，我升级到 3.0.504 并且它工作（我的操作系统是 windows）

如本期所述：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
