怎么配置 redis 的connection呢

我看 connection 都写死在 代码里的。我想换个 connection ，只能通过创建几个类用 dependencies.php 替换吗？

还有个依赖库已经废弃了
```
Package mix/redis-subscribe is abandoned, you should avoid using it. Use mix/redis-subscriber instead.
```
并且这个依赖库，不支持 prefix，导致本库根本就用不了 https://github.com/mix-php/mix/issues/100#event-6088492645

目前我是另外通过 class_map让它支持prefix的

Start by locating the hard-coded Redis connection and reviewing dependencies.php and the current class_map workaround. Check the abandoned mix/redis-subscribe dependency, the suggested mix/redis-subscriber replacement, and the linked upstream issue about prefix support; done should include a documented way to select a connection and resolve the prefix limitation.
