Spezialisierung Spring Boot REST API: Real-World Java Projects

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 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 design, development, and deployment of a real-world RESTful API using Spring Boot and Java. Structured around the creation of an Employee Management System, the course helps learners progress from project setup to the implementation of controller logic, business services, data access layers, and application configuration.

Through a modular approach, learners will first construct domain models, organize service and repository logic, and then design REST endpoints for handling CRUD operations. The final section focuses on bootstrapping the application, configuring runtime settings, and preparing the system for deployment. Throughout the course, learners will engage with Bloom’s-aligned objectives to: • Construct modular backend architecture using Spring Boot conventions • Design RESTful APIs using annotations and HTTP methods • Implement controller logic to process client requests • Configure application settings for flexible deployment • Integrate all layers into a scalable, production-ready API system Whether you're a developer seeking to solidify your backend skills or a student aiming to build a portfolio-grade project, this course provides both conceptual clarity and practical application.
