如何将Netty Channel对象存储在Redis数据库或任何其他解决方案中？

Question

As i am using netty to make chat application.As i have cluster of netty servers.

As i am storing channel id of all clients in Redis to have reference of all channels which are connected to netty servers.

I want to store all Channel objects to Redis so that from any node or instance i can get all clients Channel objects because node on which if i want to get other clients Channel which are created on some other node, How to get those client Channel objects which reside on other node or instance?

So its better to store client Channel object to redis so from any node i can get any client Channel object. but Channel implementing class is not Serializable in netty.

1. So how to store Channel object in Redis?
2. Is it good idea to serialize Channel object by extending Channel object and implementing Serializable interface?
3. If this solution is not good, then how to get any client Channel object from any node in a netty cluster?

Thanks.

Answer 1

Channel in Netty contains implicitely all network aspects (socket, nio support, tcp or udp or ...), therefore you can not serialize it (a network connection cannot be serialized).

But you can serialize the remote address. Note however that the "id" is not configurable, meaning you cannot force its value for one channel. So you might use something like:

In Redis or so: (your id being the key)

• your id
• remote host address (and port probably)
• any data for the context

In your JVM (node): (map where your id is the key)

• your id
• the channel object
