搜了一下，貌似就这个靠点谱：

https://github.com/lettuce-io/lettuce-core/issues/930

于是就打算升级lettuce-core包来解决这个问题，通过一点点升级确认，好像升级到6.1.0时，这个错误没有了：

        <dependency>
            <groupId>io.lettuce</groupId>
            <artifactId>lettuce-core</artifactId>
            <version>6.1.0.RELEASE</version>
        </dependency>

但是好景不长，第二天同事说另一个用到lua脚本的服务启动不了了，报错：

明显是spring-data-redis的版本和lettuce-core版本不搭导致的冲突，但是spring-data-redis版本不敢再升级了。

于是只好暂时按兵不动，反正最开始的报错也不影响使用。
