Introduction- Spring Boot is an open-source framework that simplifies the development of production-ready applications in the Spring ecosystem. These small projects will help you:
Understand Spring Boot basics. Learn how to build REST APIs. Work with Spring Data JPA to integrate databases. Implement security using Spring Security. Deploy Spring Boot applications. Each project is organized in its own folder with a clear objective and step-by-step instructions.
Prerequisites- Before you begin, ensure you have the following installed:
Java Development Kit (JDK) 17+ Maven or Gradle IntelliJ IDEA or any other Java IDE Basic knowledge of Java and Spring Framework Postman for testing APIs (optional)
