Learn to build a Spring Boot 4 REST API from scratch in this 26-minute tutorial that demonstrates the rapid development capabilities of the Spring framework. Set up your development environment with IntelliJ IDEA and JDK, then use Spring Initializr to bootstrap your project quickly. Create REST controllers using @RestController and request mappings, build a simple domain model with Java records, and implement GET endpoints that automatically return JSON responses. Understand the distinction between quick demonstration code and production-ready applications, as this tutorial focuses on getting a working CRUD API running rapidly rather than comprehensive production architecture. Gain hands-on experience with Spring Boot 4's streamlined development process while learning essential concepts like controller creation, JSON serialization, and REST endpoint configuration. The tutorial requires basic to intermediate Java knowledge and IntelliJ IDEA installation, providing a foundation for understanding Spring Boot's approach to rapid API development compared to other programming languages and frameworks.
