Building RESTful APIs with Spring Boot

Modern backend development relies heavily on robust, scalable, and secure APIs. If you want to transition into backend engineering, mastering RESTful web services with Spring Boot is one of the most valuable skills you can acquire. This text-based course guides you from backend basics to deploying fully functional REST APIs. You will start with the fundamental concepts of HTTP, REST architecture, and dependency injection before moving on to hands-on API design and database integration. What you'll learn: Understand the core principles of RESTful architecture and HTTP methods; Configure Spring Boot projects using modern dependency injection and configuration patterns; Create robust controllers, services, and repositories to handle backend business logic; Implement modern Java records as Data Transfer Objects for cleaner data handling; Apply relational database integration using Spring Data JPA for persistent storage; Design structured error handling using modern RFC-compliant Problem Details; Test your API endpoints effectively using Spring's built-in testing utilities. The course begins with essential backend terminology and Spring framework fundamentals. You will then progress through step-by-step written tutorials and code-based exercises, learning how to structure, build, and secure your API. This course is designed for beginners new to backend development and Java developers looking to transition into web services. No prior Spring Boot experience is required.
