/**
|
||||||
|
* 拓展 DefaultStreamMessageListenerContainer 实现,解决 Spring Data Redis + Redisson 结合使用时,Redisson 在 Stream 获得不到数据时,返回 null 而不是空 List,导致 NPE 异常。
|
||||||
|
* 对应 issue:https://github.com/spring-projects/spring-data-redis/issues/2147 和 https://github.com/redisson/redisson/issues/4006
|
||||||
|
* 目前看下来 Spring Data Redis 不肯加 null 判断,Redisson 暂时也没改返回 null 到空 List 的打算,所以暂时只能自己改,哽咽!
