Java Web Internals Unlock the secrets of Java web servers, frameworks, and application architecture (Francisco Isidro Massetto)（Z-Library）

Author： Francisco Isidro Massetto

Key benefits • 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 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. Who is this book 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.
