Spring PetClinic is a sample Spring Boot application that demonstrates building a web application with the Spring framework.
The project solves the problem of providing a concrete, runnable example for developers learning Spring. It implements a pet clinic management system with features for managing veterinarians, pets, and visit records. The application uses Spring Boot for rapid development, supports both Maven and Gradle as build tools, and includes a web interface accessible through a browser. The architecture demonstrates standard Spring patterns including data access, service layers, and web controllers.
Developers should use this project as a learning resource or reference implementation rather than as a foundation for production systems. It suits anyone new to Spring who wants to see how a complete application fits together, from database configuration through web endpoints. The project supports multiple database backends: it defaults to an in-memory H2 database for quick startup, but also provides configurations for MySQL and PostgreSQL when persistent storage is needed. The application requires Java 17 or later and can be run directly from the command line, within an IDE, or as a containerized image built through the Spring Boot build plugin.
The project maintains active build automation with both Maven and Gradle pipelines. Documentation acknowledges that legacy presentation materials exist but directs users to the current repository and its documentation for accurate information. The application includes database setup scripts for MySQL and PostgreSQL, and provides docker-compose configuration for running database services alongside the application.
