"The best developers of the future will have a deep appreciation for the fundamentals that make great software possible, and also deeply enjoy the craft of development. This book, built on Professor Isidro's beliefs of the importance of fundamentals and on having fun developing software, gives you both."
Key Features
Build a multithreaded HTTP server and application container using Java sockets
Understand and replicate the internal mechanics of Tomcat and Jakarta EE, and Spring features
Develop a modular Java framework with annotation-based routing and dependency injection
Book Description
Ever wondered how web servers like Tomcat process requests, or what really happens behind frameworks such as Spring? This book takes you beneath the surface of Java web development to uncover the why behind the tools you use every day. Rather than focusing solely on coding recipes, this book emphasizes the underlying concepts and design principles that govern how web servers and frameworks operate.
Starting with low-level socket programming, you'll build a multithreaded HTTP server from the ground up and extend it into a lightweight application server capable of handling dynamic content.
Along the way, you'll master HTTP request parsing, response generation, servlet-like request handling, and Java reflection and annotations for metaprogramming. As you progress, you'll evolve this infrastructure into your own Java framework with embedded Tomcat, annotation-driven routing, object serialization with Jackson, and basic dependency injection modeled on Jakarta CDI.
By the end of this journey, you'll understand the principles behind them, enabling you to reason about system design, troubleshoot complex issues, and apply these concepts across frameworks and programming languages.
What you will learn
Implement a multithreaded web server using Java sockets
Decode and construct HTTP requests and responses manually
Build an application container to serve dynamic Java classes
Serialize and deserialize JSON data using Jackson
Structure projects with modular static and dynamic content
Replicate the internal mechanics of Tomcat, Jakarta EE, and Spring features
Manage lightweight session handling and routing logic
Create and deploy a complete custom Java web framework
Who this book is for
Java developers, computer science students, and educators seeking a deep, hands-on understanding of web server internals and application framework design. Prior knowledge of Java and basic networking concepts is recommended.
