Creating REST APIs in Java with Spring Boot 3. This comprehensive course introduces you to building modern, scalable web APIs using the power of Java and Spring Boot 3. From basic concepts to advanced techniques like database integration and securing APIs with Spring Security and JSON Web Tokens (JWT), this course covers it all.

What you will learn

A solid foundation in RESTful architecture: Learn the principles of resource-based design, HTTP methods, and status codes.
Setting up and configuring Spring Boot projects: managing dependencies and using its features to simplify API development.
Hands-on experience with test-driven development (TDD): writing unit and integration tests to create robust and maintainable APIs.
Using Spring Data JPA: Perform basic CRUD operations and manage data persistence seamlessly within a Spring Boot application.
Adding security to APIs: authentication and authorization mechanisms, JWT tokens, and role-based access control.
Master error handling and validation: Provide clear, consistent, and user-friendly responses to API consumers.
Testing APIs with tools like HTTP Client and Postman: Effectively documenting endpoints using Swagger/OpenAPI.

This course is suitable for people who:

Java developers who want to expand their skills by learning to build RESTful APIs with Spring Boot 3.
Backend developers who want to use Spring Boot capabilities to simplify API development and better understand the Spring ecosystem.
Students or recent graduates with knowledge of Java who are looking to gain practical, industry-relevant skills in API development.
Engineers who want to learn test-driven development (TDD) on a real project and build reliable APIs using test-first approaches.
Developers looking to migrate from monolithic applications to microservices will benefit from learning how to create self-contained, scalable APIs using Spring Boot, a popular choice for microservices.
People seeking roles such as backend developer, API developer, or software engineer will gain foundational skills for developing, securing, and deploying APIs.
