What version of Spring Boot does this skill support?

This skill is specifically optimized for Spring Boot 3.3 and higher, utilizing modern features like Java records and updated Jakarta EE namespaces.

How does it handle application configuration?

It promotes using @ConfigurationProperties with @Validated, which groups related properties into a single object and validates them at startup, preventing runtime configuration errors.

Where should I apply @Transactional according to these patterns?

Transactions should be applied at the service layer (application services) to ensure that business operations are atomic, rather than at the controller or repository levels.

Does this skill work with legacy Java versions?

While the logic applies broadly, the code examples and patterns assume Java 17+ and Spring Boot 3, specifically utilizing records and Jakarta validation.

Why does this skill discourage @Autowired on fields?

Constructor injection is the industry standard because it allows for final fields, easier unit testing without reflection, and ensures the bean is never in an inconsistent state.

API 开发

Implements modern Spring Boot 3 standards for dependency injection, type-safe configuration, and robust RESTful API architecture.

This skill provides a comprehensive framework for building production-grade Spring Boot 3.3+ applications using current industry best practices. It enforces architectural standards such as constructor-based dependency injection to improve testability, type-safe configuration properties with validation to prevent runtime errors, and clear transaction boundaries at the service layer. By leveraging modern Java features like records for DTOs and optimized configuration scanning, it helps developers create maintainable, scalable, and idiomatic Spring Boot microservices and web applications.
