Provides dependency injection patterns for Spring Boot projects, including constructor-first design, optional collaborator handling, bean selection, and wiring validation. Use when creating services and configurations, replacing field injection, or troubleshooting ambiguous or fragile Spring wiring.
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 Dependency Injection ## Overview Provides constructor-first dependency injection patterns for Spring Boot: - mandatory collaborators via constructor injection - optional collaborators via `ObjectProvider` or no-op fallbacks - bean selection via `@Primary` and `@Qualifier` - validation via minimal context tests before full integration ## When to Use Use this skill when: - creating a new `@Service`, `@Component`, `@Repository`, or `@Configuration` class - replacing field injection in legacy Spring code - resolving multiple beans of the same type with qualifiers or primary beans - handling optional features, adapters, or integrations without null-driven wiring - reviewing circular dependencies or brittle context startup failures - preparing code for direct constructor-based unit testing ## Instructions ### 1. Separate mandatory and optional collaborators For each class, identify: - mandatory collaborators required for correct behavior - optional collaborators that enable integrations, caching, notifications, or feature-flagged behavior …

How to install
mdr add giuseppe-trisciuoglio/developer-kit/spring-boot-dependency-injection@sha256:1490386566fdf73aThe line at the top of this page pins the label git:20260324.a02e282, 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.
