Could not resolve placeholder 'redis.pool.maxActive' in value "${redis.pool.maxActive}" 告诉你读取不到配置，看下是不是配置的参数有问题，没对应上

Could not resolve placeholder 'redis.pool.maxActive' in value "${redis.pool.maxActive}" 问题一个一个来，先去看是否定义了这个？

Could not resolve placeholder 'redis.pool.maxActive' in value "${redis.pool.maxActive}" 解析不到这个值，看一下配置文件里的命名。
