Practicing Spring Boot: Web App Development and Architecture

Building modern web applications requires a firm grasp of framework internals and best practices. This text-based guide is designed to help you validate your knowledge of Spring Boot, moving you from passive reading to active comprehension. You will explore core concepts, test your understanding of dependency injection, and learn to avoid common architectural pitfalls. By working through structured explanations and real-world scenarios, you will develop the confidence to design and debug spring-based applications independently. What you'll learn: Understand the Spring Boot starter dependency model and auto-configuration mechanics; Design clean RESTful APIs using standard controller annotations and modern JSON serialization; Configure application properties, profiles, and environment variables for different deployment stages; Apply database integration principles using Spring Data JPA and modern connection pooling; Implement secure authentication flows and understand zero-trust security basics in web applications; Learn how to write robust unit and integration tests using pytest-like test structures adapted for Spring. The course starts with essential terminology, core container concepts, and configuration basics before moving into database connectivity, API design, and security principles. This course is designed for beginning developers who have a basic grasp of Java and want to establish a rock-solid foundation in Spring Boot.
