Spring — Database migrations (Flyway)

Apply Flyway migration guidelines for Spring Boot.

What is covered in this Skill?

  • flyway-core and database-specific Flyway modules (e.g. PostgreSQL) with Spring Boot BOM
  • Versioned SQL under src/main/resources/db/migration (V{version}__{description}.sql)
  • spring.flyway.* properties: locations, baseline-on-migrate, validate-on-migrate
  • Optional Java migrations (BaseJavaMigration) for data backfills
  • Forward-only discipline: do not rewrite applied migrations in shared environments
  • Coordination with @311-frameworks-spring-jdbc and @312-frameworks-spring-data-jdbc

Scope: Apply recommendations based on the reference rules and good/bad examples.

Constraints

Before applying Flyway or SQL changes, ensure the project compiles. After improvements, run full verification.

  • 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 good/bad patterns

When to use this skill

  • Add or review Flyway migrations in a Spring Boot project
  • Configure spring.flyway or db/migration layout
