What are the migration paths between them?

I can only answer questions about liyifeng1994/ssm or reactivex/rxjava.

These are two fundamentally different projects with no direct migration path between them:

• liyifeng1994/ssm is an educational tutorial on integrating the SSM framework (SpringMVC + Spring + MyBatis), a traditional Java web application stack. It's designed to teach servlet/JSP-based web development [README.md:L1-L3].

• reactivex/rxjava is a reactive programming library for composing asynchronous and event-based programs using observable sequences.

They serve entirely different purposes and operate at different architectural levels. SSM is a full-stack web framework for building server-rendered applications, while RxJava is a library for handling reactive streams and asynchronous data flows.

If you're asking whether you could refactor an SSM application to use RxJava:

• You could integrate RxJava into an SSM-based application to handle asynchronous operations (e.g., non-blocking database calls, async HTTP requests), but this wouldn't be a "migration" between the two projects—it would be adding RxJava as a dependency within an SSM architecture.

Could you clarify what kind of relationship or comparison you're looking for between these two repositories?
