Master Spring Boot REST APIs: CRUD, Exception Handling, JWT Security, and Database Integration
What you'll learn
Build complete CRUD REST APIs using Spring Boot and JPA, including database configuration, entity mapping, and repository integration.
Design clean and maintainable Spring Boot applications using layered architecture, service and controller best practices, and proper API structure.
Implement robust exception handling and error management using custom exceptions, global exception handlers, and correct HTTP status codes.
Secure Spring Boot applications using Spring Security and JWT, including authentication, authorization, filters, and testing secured APIs with Postman and cURL.
Requirements
Basic knowledge of Java
Description
This course is a hands-on guide to building secure and production-ready REST APIs using Spring Boot. You will learn to implement CRUD operations, exception handling, and Spring Security with JWT authentication through real-world examples.The course covers Spring Boot project setup, database integration using JPA and MySQL, and building clean REST APIs using controller, service, and repository layers. You will also implement custom exceptions, global exception handling, and proper HTTP status codes, ensuring robust and maintainable applications. You'll learn how to create meaningful error messages, log exceptions for troubleshooting, and gracefully handle unexpected scenarios to improve API reliability and user experience.You'll explore Spring Security basics, form-based and in-memory authentication, and then move to JWT-based authentication and authorization. Throughout the course, you'll test APIs using Postman and cURL, debug common issues, fix real-world errors, and understand logging using print statements and monitoring techniques for better application management. You will also gain practical knowledge of API versioning, input validation, securing endpoints against common vulnerabilities, and implementing best practices for error responses efficiently.By the end of this course, you'll be confident in building, securing, and testing Spring Boot REST APIs that follow industry best practices, deployable in real-world production environments, and scalable for future enhancements. You'll also be ready to integrate these APIs with frontend applications or microservices architecture efficiently and effectively.
