Spring Boot REST API: Real-World Java Projects

This project-based course equips learners with the skills to design, construct, and implement RESTful APIs using Spring Boot through a complete case study of a Pet Clinic application. Following a modular structure, the course progresses from project setup and domain modeling to advanced layers such as exception handling, serialization, and RESTful service integration. In Module 1, learners will create and organize entity classes, define base structures using JPA, and construct repository interfaces for data access. Module 2 guides learners to develop robust exception handling mechanisms and customize JSON serialization using Jackson, ensuring clean and secure API responses. Finally, in Module 3, learners will build REST controllers, integrate service layers, and execute CRUD operations through structured HTTP endpoints. Throughout the course, emphasis is placed on applying best practices in layered architecture, analyzing component responsibilities, and evaluating results through testable and maintainable API endpoints. By the end of the course, learners will be able to: • Construct RESTful services using Spring Boot and Spring Data JPA • Implement exception handling strategies using Spring's controller advice model • Apply custom serialization and re-serialization for controlled JSON output • Develop and deploy a fully functional, modular REST API project • Demonstrate complete CRUD functionality using integrated service and controller layers

This hands-on course guides learners through the structured development and testing of a RESTful Book Store API using REST Assured and Java. Designed for learners with intermediate Java experience, the course applies real-world case study methodology to build foundational skills in RESTful API testing. Learners will set up a Java testing project, integrate key dependencies, and demonstrate mastery over authentication workflows by generating and authorizing users via secure tokens. Through practical exercises, learners will implement core CRUD operations, interpret API responses, and evaluate end-to-end outcomes using HTTP methods and status codes. By the end of this course, learners will be able to: • Configure REST Assured in a Java environment for scalable test automation. • Construct and execute secure API requests using token-based authentication. • Perform and validate create, read, update, and delete operations for managing book data. • Analyze API test results to verify functionality and system behavior. Whether you are looking to solidify your API testing skills or work toward automation in enterprise applications, this course equips you with the knowledge to apply, analyze, and evaluate RESTful services using REST Assured.

This hands-on course is designed to guide learners through the complete process of building, executing, and validating RESTful API tests using Java and REST Assured. Anchored in a real-world case study—the Employee Database API—this course enables learners to configure a robust testing environment, construct dynamic JSON payloads, and apply critical REST operations (GET, POST, PUT, DELETE) through structured automation scripts. Learners will explore best practices for mapping JSON to Java POJOs, asserting API responses using Hamcrest matchers, and evaluating final test outcomes to confirm successful CRUD operations. Each module is structured with instructional clarity and reinforced with quizzes to strengthen comprehension and practical skills. By the end of the course, learners will be able to confidently develop, execute, and verify REST API automation workflows in Java, applying principles that reflect industry standards in software quality engineering.
