Redis Cache throw exception: java.net.ConnectException: Connection refused

[hongwei1]

implicit val scalaCache = ScalaCache(RedisCache(url, port))

I follow this page for Redis, just use the simple function:

val myValue: Option[Cat] = sync.get("eric")
myValue: Option[Cat] = None

It should return None, but it returns the crazy exception. It seems my Redis server is dead ...
