我将Redt Spring Data（1.8.9.RELEASE）与生菜（4.5.0.Final）用作底层Redis驱动程序。它使用的是4.1.29版的netty。
我们正在使用Redis ElastiCache并启用了加密传输和静态加密。
我遇到了错误。我看到了与netty的NotSslRecordException相关的帖子，其中suggested cause与http和https不匹配。但是我们通过tcp与弹性痛联系。

从线程堆栈看，您似乎正在将Spring Data Redis与Lettuce库结合使用。
在创建LettuceClientConfiguration时，您需要通过设置useSSL（）选项来告诉Client使用SSL。 https://docs.spring.io/spring-data/redis/docs/current/api/org/springframework/data/redis/connection/lettuce/LettuceClientConfiguration.html#isUseSsl--
我希望这会有所帮助。
