Summary
LGTM — adds WebFlux support for Seata distributed transaction context propagation. The ReactiveSeataHandlerFilter correctly binds/unbinds XID from request headers to RootContext, mirroring the servlet-based handler pattern for reactive applications.
Review Notes
- Clean implementation following the existing servlet filter pattern
- Proper use of
Mono.defer()for cleanup in the reactive chain @ConditionalOnWebApplication(type = REACTIVE)ensures this only activates for WebFlux apps
