spring-boot-conventions

To enforce consistent Spring Boot backend architecture, apply a standardized three-layer pattern—Controller, Service, and Repository—across your codebase. This approach prevents pattern drift and ensures new code follows predictable structural guidelines.

The standard package layout for a Spring Boot backend separates classes into specific directories: config, controller, dto, entity, enums, repository, and service. This structure keeps related classes grouped logically and makes the codebase easier to navigate.

Yes, you should use Java records for DTOs in Spring Boot applications. Defining DTOs as records provides immutability and reduces boilerplate code, aligning with modern coding conventions to standardize data transfer structures.

Structure JPA entities in a Spring Boot codebase by applying proper Lombok annotations for boilerplate reduction and mapping database columns accurately. Enums should be persisted as STRING values to ensure readability and database compatibility.

The best way to review Spring Boot controllers and services for anti-patterns is checking them against prescribed class guidelines. Ensure controllers only handle HTTP requests and services contain business logic, avoiding common structural drift.

Yes, you can apply Spring Boot coding conventions during code refactoring. Use the defined architectural patterns to guide the restructuring of existing controllers, services, repositories, DTOs, and entities into the standardized three-layer layout.
