学习atguigu的Redis配置类RedisConfig中PropertyAccessor.ALL报错

Question

问题遇到的现象和发生背景

学习尚硅谷的Redis6，，RedisConfig报错，
有没有学习atguigu的Redis的？学到这里卡死了，百度没查不到。
尚硅谷的Redis6，RedisConfig配置类。老湿一顿说：咱们快速的引入以下依赖，但就是细讲。搞死我了。百度也查不到

运行结果及报错内容

运行不了，直接报错，报红
// 这里的 .ALL 以及下面的都报错。
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);

我的解答思路和尝试过的方法

百度，各种轮胎博客，都没查到相关的

我想要达到的结果

解决bug，然后继续学习
