Rest API | Web Service Tutorial
MindCraft Backend Web Dev - Spring, and Microservices Lecture 7
Course by: MindCraft

In this comprehensive lecture, we explore RESTful web services using Jersey and Spring. This session is designed to equip you with the knowledge and skills to build, test, and manage RESTful APIs effectively. Whether you're new to REST APIs or looking to enhance your existing skills, this lecture covers essential concepts and practical implementations to help you get started.

We begin with an introduction to REST APIs and their significance in modern web services. You'll learn how to set up a Jersey project in Eclipse and run your first RESTful application. We’ll guide you through creating resource classes, managing lists, and integrating a mock repository for testing purposes. The session also covers how to use Postman for sending requests and handling JSON data.

As we advance, you'll dive into database integration with MySQL and learn how to handle both JSON and XML formats in your services. We’ll cover advanced topics such as updating and deleting resources, and recap the key concepts covered. Finally, we'll introduce Spring Boot for building RESTful services and demonstrate how to integrate Spring Data JPA for efficient data management.
