Building REST APIs with Spring Boot — Java + Spring Boot Roadmap
Turning Spring Boot into a working HTTP API
Steps in Building REST APIs with Spring Boot
- Spring MVC & the DispatcherServlet — intermediate · How an incoming HTTP request gets routed to your controller code
- REST Controllers & Request Mapping — intermediate · @RestController, @GetMapping/@PostMapping and routing incoming requests
- Request/Response Bodies & DTOs — intermediate · Mapping JSON to Java objects and using DTOs to decouple API shape from entities
- Path Variables, Query Params & Validation — intermediate · Extracting request data and validating it with Bean Validation annotations
- Exception Handling (@ControllerAdvice) — intermediate · Centralizing error handling and returning consistent, meaningful error responses
- API Versioning Strategies — advanced · URI versioning, header versioning and evolving an API without breaking clients
- Mini Project: Building a CRUD REST API — intermediate · Build a complete REST API with proper DTOs, validation and error handling
