Comprehensive best practices guide

java-springboot is an agent skill from the github/awesome-copilot collection that gives best practices for building production-ready Spring Boot applications in Java. It covers project setup and structure, dependency injection and components, configuration management and the web layer. On setup it recommends Maven or Gradle for dependencies, Spring Boot starters such as spring-boot-starter-web and spring-boot-starter-data-jpa to keep dependency management simple, and a package structure that groups code by feature or domain, such as an order package or a user package, rather than by technical layer. For dependency injection it recommends constructor injection for every required dependency, with the fields declared private and final, so the components are easier to test and their dependencies are explicit. It explains when to use the stereotype annotations for components, services, repositories and controllers. The configuration section covers externalized configuration, type-safe properties, and environment profiles, so the same build runs in development, test and production with different settings. The web layer section covers RESTful API design. The skill is useful for Java teams building or reviewing Spring Boot services, and for developers who want a consistent baseline. Configuration often contains secrets, which should come from the environment or a secret store rather than from files in the repository. The skill is installed with the skills CLI from the github/awesome-copilot repository. Its skills.sh page showed about 21.0K installs and passing results from three security audits at the time of the scan.
