spring-boot-dependency-injection

This skill captures the dependency injection approach promoted in this repository: constructor-first design, explicit optional collaborators, and deterministic configuration that keeps services testable and framework-agnostic.

Follow these steps to implement proper dependency injection in Spring Boot:

List all collaborators required by each class. Distinguish between mandatory dependencies (required for operation) and optional dependencies (feature-specific).

为 Spring Boot 项目提供依赖注入模式，涵盖构造函数优先模式、可选协作者处理、bean 选择和验证实践。在配置 bean、连接依赖项或排除注入问题时使用。 来源：giuseppe-trisciuoglio/developer-kit。
