SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Spring Framework 7 / Spring Boot 4 conventions codify modern idioms and defaults to keep Spring projects consistent, maintainable, and aligned with the latest platform capabilities.

Core Features & Use Cases

  • Package layout — by feature, not by layer, with public api at the feature boundary and typed sub-packages for internal classes.
  • Dependency injection — constructor injection only; avoid Lombok; enforce explicit constructors.
  • HTTP clients — prefer declarative HttpExchange clients for external calls and avoid RestTemplate.
  • Web layer and DTOs — controllers expose DTOs, validate inputs, and avoid returning entities.
  • Observability and configuration — per-module configuration properties, structured logging, and AOT-friendly setup.

Quick Start

Restructure your codebase to feature-based packages, switch to constructor injection, and implement HTTP clients using @HttpExchange to align with the conventions.

Frequently Asked Questions about spring-boot-4-conventions

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What are the Spring Boot 4 conventions for dependency injection?▼

Spring Boot 4 conventions mandate constructor injection exclusively and avoiding Lombok to ensure explicit, AOT-friendly, and testable code structures.

How do I structure packages for a modern Spring Boot application?▼

Structure Spring Boot packages by feature rather than layer, placing public API at the feature boundary and organizing internal classes into typed sub-packages.

Should I use RestTemplate or HttpExchange for HTTP clients in Spring Framework 7?▼

Spring Framework 7 conventions prefer declarative HttpExchange clients for external calls and explicitly avoid using RestTemplate to align with modern platform capabilities.

Why avoid returning entities directly from Spring Boot controllers?▼

Spring Boot controllers should expose DTOs and validate inputs rather than returning entities to maintain a clean web layer and support structured API boundaries.

How do I configure Spring Boot 4 application properties for AOT compatibility?▼

Configure Spring Boot 4 properties per-module and adopt structured logging alongside an AOT-friendly setup to ensure consistent maintainability across project modules.

Does Spring Framework 7 require avoiding Lombok for AOT compilation?▼

Yes, Spring Framework 7 conventions require avoiding Lombok and enforcing explicit constructors to support AOT-friendly compilation and ensure fully testable code.
