Build & Test REST APIs with POSTMAN and Spring Boot

Overview

By the end of this course, learners will be able to design, implement, test, and configure RESTful APIs using Spring Boot and POSTMAN while managing employee data through a complete backend application. Learners will gain hands-on experience in building a structured Employee Management System, implementing CRUD operations, handling exceptions effectively, and configuring application properties for reliable execution. This course equips learners with practical backend development skills by guiding them through a real-world project rather than isolated concepts. Learners will understand how application layers interact, how REST controllers process HTTP requests, and how repositories manage persistent data. The course also emphasizes professional API practices, including structured error handling and proper use of HTTP methods, ensuring learners build APIs that are robust, maintainable, and client-friendly. What makes this course unique is its project-driven approach that mirrors real industry workflows. Instead of theoretical explanations, learners actively build and test APIs using POSTMAN, reinforcing concepts through direct application. This course is ideal for aspiring backend developers, Java learners, and professionals looking to strengthen their REST API development and testing skills using Spring Boot.

Syllabus

Project Setup and Core Application Structure

This module introduces the Employee Management System project using Spring Boot and POSTMAN, guiding learners through project initialization, dependency configuration, application startup, and the creation of core domain models and repositories required for backend REST API development.

API Logic, Error Handling, and Configuration

This module focuses on building robust REST APIs by implementing controllers, handling application exceptions effectively, and configuring environment-specific properties to ensure reliable execution, maintainability, and proper API behavior.
