Description

分布式事务需要跨模块的通讯，模块与模块之前需要传递事务的信息，为了不影响业务的情况下，需要将传递数据与业务解耦封装，在框架层面做数据拦截处理。

难点：RPC通讯框架较多，不同的框架存在通讯机制上的差异。

Research direction
Investigate how different RPC frameworks (Dubbo, Spring Cloud, Motan) implement interceptors for passing distributed transaction context. Review the tx lcn codebase for existing interceptor patterns and identify a common interface that can adapt to each framework's communication mechanism. Consider consulting the issue comments for additional requirements and maintainer feedback.
