I would like to maintain MCP server state persisted (sessionId)

Now the session id is maintained in memory in a map. But since I have my MCP server multiple pods running, I would like the state to be persisted in redis or in a DB.

I would like to override the session Validator as a parameter in the HttpServletStreamableServerTransportProvider

Current Behavior

Currently only the session creation can be customised but not maintaining the state fully.

Context

I am not able to implement stateful session in a distributed setup

从 HttpServletStreamableServerTransportProvider 开始，检查会话创建、验证以及内存中的会话映射是如何处理的。定义一个用于自定义会话验证和持久化的扩展点，使其能够跨多个 pod 工作，并以 Redis 或数据库为目标；当有状态会话不再依赖单个进程时，即视为完成。
