| description | Use when you need to design or implement MongoDB data access in Spring Boot — including document modeling, Spring Data Mongo repositories/templates, indexing, optimistic concurrency, and error handling. This should trigger for requests such as Add MongoDB in Spring Boot; Review Spring Data Mongo design; Improve error handling for Mongo writes; Model MongoDB documents for a Spring Boot service; Configure Spring Data MongoDB indexes or transactions.

Spring Boot — MongoDB
Apply Spring Data MongoDB guidance with concrete examples for design, implementation, and error handling.
Constraints
Compile before MongoDB 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 MongoDB in Spring Boot
- Review Spring Data Mongo repositories/documents
- Improve duplicate key handling, retries, or optimistic locking in Mongo flows
- Model MongoDB documents for a Spring Boot service
- Configure Spring Data MongoDB indexes or transactions
Workflow
- Read reference and assess project context
Read references/315-frameworks-spring-mongodb.md and inspect persistence setup before proposing changes.
- Gather scope and decide target improvements
Identify data model, consistency, and query requirements to define safe improvements.
- Apply framework-aligned changes
Implement/refactor mappings, repositories, indexes, and failure handling policies.
- Run verification and report results
Execute build/tests and summarize what changed, what was verified, and follow-up actions.
