| description | Use when you need to design or implement Kafka messaging in Spring Boot — including topic design, producer/consumer implementation, JSON serialization with Boot factory customizers, Testcontainers `@ServiceConnection` integration tests, retries and dead-letter topics, idempotency, and error handling. This should trigger for requests such as Add Kafka in Spring Boot; Review Spring Kafka consumers; Improve retries and DLT in Spring Kafka; Configure Spring Kafka topics serializers or listener containers; Add Spring Kafka dead-letter topic handling.

Spring Boot — Kafka messaging
Apply Spring Kafka guidance with concrete examples for design, implementation, and error handling.
Constraints
Compile before messaging refactors; verify after changes.
- MANDATORY: Run
./mvnw compile or mvn compile before applying any change
- SAFETY: If compilation fails, stop immediately
- VERIFY: Run
./mvnw clean verify or mvn clean verify after applying improvements
- BEFORE APPLYING: Read the reference for detailed rules and examples
When to use this skill
- Add Kafka in Spring Boot
- Review Spring Kafka consumers/producers
- Improve retries, dead-letter topics, or idempotency in Spring Kafka
- Configure Spring Kafka topics serializers or listener containers
- Add Spring Kafka dead-letter topic handling
Workflow
- Read reference and assess project context
Read references/314-frameworks-spring-kafka.md and inspect current messaging setup before proposing changes.
- Gather scope and decide target improvements
Identify reliability and throughput goals and define the minimum safe set of changes.
- Apply framework-aligned changes
Implement/refactor Spring Kafka configuration, producer/consumer logic, and failure handling.
- Run verification and report results
Execute build/tests and summarize what changed, what was verified, and follow-up actions.
