In this course, you will learn how to build and secure modern REST APIs with Java 25, Spring Boot 4, Spring Security 7, JWT, Spring Data JPA with Hibernate 7, and MySQL. This is a brand-new course built using the latest versions of Java 25, Spring Boot 4, and Spring Security 7. The entire course is designed for beginners and intermediate developers who want practical, real-world experience. Every concept is explained clearly, and every feature is demonstrated through hands-on projects.
We begin by understanding the foundations of REST. You will learn what REST APIs are, how they work, how clients communicate with servers, and what makes a good API design. We cover important topics such as resources, endpoints, HTTP methods, status codes, and best practices used in real applications. This gives you a strong base before writing any code.
After building this foundation, we move into real Spring Boot development. You will create a Spring Boot 4 project, explore the folder structure, and understand how Spring Boot manages configuration and dependencies. From there, we start building REST APIs step by step by creating controllers, services, repositories, and models. This helps you understand how real backend applications are structured.
Next, we connect our APIs to a MySQL database and build complete CRUD operations. Through a Task Management project, you will learn how to store, update, retrieve, and delete data using Spring Data JPA. You will also learn how to write clean code, validate input, and handle exceptions so your API always returns clear and consistent responses. Once you are comfortable with CRUD, we move to more advanced backend design. You will build REST APIs for a One-To-Many relationship using a User–Blog mini-project. This helps you understand entity mapping, cascading, lazy loading, and designing APIs that work with relational data.
