Spring Boot Best Practices SKILL.md skillA
Spring Boot Best Practices from rueclaw/public-data is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rueclaw/public-data/Spring Boot Best Practices@git:20260213.c690ecfPins git:20260213.c690ecf in mdr.lock. Pin the fingerprint instead.

Generate Spring Boot components following modern Java best practices and team conventions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Spring Boot Code Generation Guidelines
When generating or reviewing Spring Boot code, follow these best practices:
## Dependency Injection
- **Use constructor injection**, never field injection with @Autowired
- Mark injected fields as `private final`
- Let Lombok's `@RequiredArgsConstructor` generate constructors when appropriate
```java
// Good
@Service
@RequiredArgsConstructor
public class UserService {
private final UserRepository userRepository;
private final EmailService emailService;
}
// Avoid
@Service
public class UserService {
@Autowired
private UserRepository userRepository; // Field injection - avoid
}
```
## Package Structure
Follow standard Spring Boot layering:
```
com.example.project/
├── controller/ # REST endpoints, @RestController
├── service/ # Business logic, @Service
├── repository/ # Data access, extends JpaRepository
├── model/ # JPA entities, @Entity
├── dto/ # Data transfer objects
├── config/ # Configuration classes, @Configuration
└── exception/ # Custom exceptions and @ControllerAdvice
```
## REST Controllers

How to install
mdr add rueclaw/public-data/Spring Boot Best Practices@sha256:bb76035a1aa7f6cdThe line at the top of this page pins the label git:20260213.c690ecf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
