Java Web Development: From Basics to Deployment

This book is your guide to the world of modern Java web development. Whether you are taking your first steps in programming or already have experience with other languages, you will find here a structured and practical guide to creating full-fledged web applications.

What the book is about

The book covers all stages of the web application lifecycle: from architecture design to server deployment. You will start with the basics of the Java language and gradually move on to learning key technologies:

• Java Basics for the Web: working with HTTP, sessions, cookies, multithreading, and security.
• Servlets and JSP: creating dynamic pages, form handling, filters, and listeners.
• Spring Framework: IoC container, Spring MVC, Spring Boot — from simple examples to a full-fledged REST API.
• Working with Databases: JDBC, JPA/Hibernate, transactions, and query optimization.
• Modern Approaches: microservices, Docker, CI/CD, testing, and monitoring.
• Deployment: configuring Tomcat, Jetty, cloud platforms (AWS, Heroku), containerization.

Who this book is for

• Beginner Java developers — get a clear roadmap: from "Hello World" to a production-ready application.
• Developers from other languages (Python, PHP, C#) — quickly master the Java ecosystem and its tools.
• Students and graduates — practical examples will help reinforce theory and build a portfolio.
• Team Leads and Architects — systematize your knowledge and learn best practices for 2024.

What you will learn

• How to design a scalable web application architecture.
• How to work with popular frameworks (Spring Boot, Hibernate).
• How to create secure REST APIs with authentication and authorization.
• How to set up CI/CD pipelines and deploy applications to the cloud.
• How to write unit tests and integration tests for web components.

Each chapter contains practical assignments, code examples, and links to repositories with ready-made projects. The book is written in a lively style, without excessive academicism — you will be able to apply the knowledge you gain immediately.

By the end of the book, you will create a full-fledged task management web application with a microservice architecture, which you can show to an employer or use as a starting template for your own projects.
