Implement Spring Data JPA repositories, entities, and queries following modern best practices. Use for creating repositories (only for aggregate roots), writing queries (@Query, DTO projections), custom repositories (Criteria API, bulk ops), CQRS query services, entity relationships, and performance optimization. Covers patterns from simple repositories to advanced CQRS with detailed anti-patterns guidance.
Implement persistence layers with Spring Data JPA. Use when creating repositories, configuring entity relationships, writing queries (derived and @Query), setting up pagination, database auditing, transactions, UUID primary keys, multiple databases, and database indexing. Covers repository interfaces, JPA entities, custom queries, relationships, and performance optimization patterns.
Rules and guidelines for working with Spring Data JPA in the project. ALWAYS use this skill when adding, removing, or modifying JPA entities, repositories, or projections. Trigger on any request that involves changing entity structure, adding new entities, modifying field annotations, updating database mappings, creating or modifying Spring Data repositories, or defining query projections (interfaces, DTOs).
Provides comprehensive guidance for Spring Data JPA including repositories, entity management, query methods, and database operations. Use when the user asks about Spring Data JPA, needs to work with JPA repositories, implement data access layers, or configure JPA in Spring.
Spring Boot 3 Java framework with enterprise patterns. Covers REST controllers, services, repositories, JPA entities, MapStruct mappers, Lombok, JWT security, Flyway migrations, and global exception handling. USE WHEN: user mentions "Spring Boot", "REST API", "enterprise Java", asks about "controller patterns", "service layer", "repository", "DTO mapping", "JWT auth", "Flyway", "MapStruct" DO NOT USE FOR: Spring Data JPA (use `spring-data-jpa`), Spring Security (use `spring-security`), Spring WebFlux (use `spring-webflux`), Spring WebSocket (use `spring-websocket`)
Rules and guidelines for working with Spring Data JDBC in the project. ALWAYS use this skill when adding, removing, or modifying Spring Data JDBC entities (@Table from org.springframework.data.relational.core.mapping), aggregates, AggregateReference links, embedded objects, @MappedCollection associations, or Spring Data JDBC repositories (CrudRepository / ListCrudRepository). Trigger on any request that touches @Table, @Column, @MappedCollection, @Embedded annotations from spring-data-relational, AggregateReference fields, @PersistenceCreator constructors, or @Query methods on JDBC repositories. Do NOT use for JPA (jakarta.persistence) entities — use the spring-data-jpa skill instead.
Build production Spring Boot applications - REST APIs, Security, Data, Actuator
Model Kotlin persistence code correctly for Spring Data JPA and Hibernate. Covers entity design, identity and equality, uniqueness constraints, relationships, fetch plans, and common ORM (Object-Relational Mapping) traps specific to Kotlin. Use when creating or reviewing JPA (Java Persistence API) entities, diagnosing N+1 or LazyInitializationException, placing indexes and uniqueness rules, or preventing Kotlin-specific bugs such as data class entities and broken equals/hashCode.
Build Spring Boot 4.x applications following best practices. Use when developing or modifying Spring Boot apps that use Spring MVC, Spring Data JPA, Spring Modulith, Spring Security, or Spring Boot testing including package structure, REST APIs, entities/repositories, service layer, modular monoliths, and REST API tests.
Spring Boot 3.x - Java framework for production-ready applications with dependency injection, REST APIs, data access, security, and actuator monitoring
Provide repeatable CRUD workflows for Spring Boot 3 services with Spring Data JPA and feature-focused architecture; apply when modeling aggregates, repositories, controllers, and DTOs for REST APIs.
Use when building Spring Boot 3.4+ applications with Java records, virtual threads, Spring Security 6, Spring Data JPA, reactive WebFlux patterns, and production-grade testing strategies.
