Who creates HttpServletRequest in Spring MVC?

🔙 From Servlets to Spring Boot 🚀 Looking back at how Java web apps evolved: 1️⃣ Before Spring – manual servlets and web.xml chaos 2️⃣ Spring MVC – the DispatcherServlet era 🌐 3️⃣ Spring Boot – embedded Tomcat, auto configuration, pure joy ☕ Sometimes, progress is just about removing boilerplate. #Java #SpringBoot #OOP #SoftwareEngineering #BackendDevelopment

☀️ Day 17 of My 90 Days Challenge – Understanding Servlets in Java Today I explored something that forms the foundation of Java web applications — Servlets. At first, I thought servlets were just old-school Java classes, but I quickly realized they’re the bridge between a web browser and a server-side application. 🔹 Servlets are server-side heroes A servlet is a Java program that lives on a server and handles client requests. It listens, processes, and responds — usually over HTTP. 🔹 Lifecycle matters Every servlet has a lifecycle: init() → setup when the servlet loads service() / doGet() / doPost() → handles each request destroy() → cleanup when the servlet is taken out of service Understanding this helps write efficient, scalable, and resource-safe code. 🔹 Request & Response Servlets are all about communication: HttpServletRequest → what the client sends HttpServletResponse → what you send back They turn Java into a server-side conversation language, bridging code with the real world. 🔹 Modern relevance Even though frameworks like Spring Boot are popular now, servlets are the foundation. Everything in Spring MVC and REST APIs is built on top of the servlet model. 💭 Key takeaway: Servlets taught me that web applications are not magic — they are a careful orchestration of requests, responses, and lifecycle management. #Day17 #Java #Servlet #WebDevelopment #Backend #CoreJava #SpringBoot #Hibernate #LearningJourney #90DaysChallenge

🚀 Did you know? You can configure your Spring MVC Servlet container without touching web.xml! 🚫📄 With WebApplicationInitializer and its abstract base class AbstractDispatcherServletInitializer, you can programmatically register your DispatcherServlet and filters, whether you prefer Java or XML-based configuration. This means: - Cleaner, code-centric setup 🧑💻 - Easy filter registration (like HiddenHttpMethodFilter or CharacterEncodingFilter) 🔄 - Async support enabled by default ⚡ - Full control to customize your DispatcherServlet as needed 🎛️ Modern Spring apps are moving away from XML. Are you? #SpringBoot #Java #WebDevelopment #SpringMVC #CleanCode

Spring WebFlux vs Spring MVC: same Spring Boot, two completely different worlds under the hood. One waits… the other reacts. If you’ve ever wondered why your APIs hit performance limits or how reactive programming actually scales better with fewer threads this deep dive will make it click. Understand the “blocking vs non-blocking” mindset in my latest Medium article. #SpringBoot #WebFlux #SpringMVC #ReactiveProgramming #Java #BackendEngineering #Microservices #Performance #Scalability #DevCommunity

Learning Spring MVC – The Backbone of Java Web Applications Recently, working with Spring MVC (Model–View–Controller). key Insights : 1. Model – Represents the data (Entities, DTOs, database tables) 2. View – UI layer (Thymeleaf/JSP) or JSON responses in REST 3. Controller – Handles incoming requests and returns responses At the center of Spring MVC is the DispatcherServlet, which acts as the Front Controller and manages the entire request workflow: 1.Receives the client request. 2.Finds the correct controller method. 3.Calls the service layer for business logic. 4.Connects to the database through repositories. 5.Sends the final response back. Spring MVC makes backend development structured, clean, and scalable. For upcoming days, I will be sharing about serverlet and CRUD operations #SpringMVC #SpringBoot #JavaDeveloper #BackendDevelopment #RESTAPI #FullStackDeveloper

📘 Servlet Life Cycle – Quick Notes Understanding the life cycle of a Servlet is key to mastering Java Web Development! 🚀 The servlet life cycle consists of five main stages: 1️⃣ Loading and Instantiation – Servlet class is loaded into memory. 2️⃣ Initialization (init()) – Servlet is initialized and ready to handle requests. 3️⃣ Request Handling (service()) – Called for each client request. 4️⃣ Destruction (destroy()) – Called before servlet is removed from memory. 5️⃣ End of Life Cycle – Servlet instance is garbage collected. 💡 Tip: This process is managed by the Servlet Container (like Tomcat) automatically. #Java #Servlet #WebDevelopment #Backend #JavaEE #CodingNotes #LearnWithAICoder

Spring Framework is like an ecosystem — each part has a purpose, yet everything works together in perfect harmony. At its core lies the Core Container, the heart of Spring, managing Beans, Context, and Dependency Injection — the roots that hold everything steady. Above it, AOP (Aspect-Oriented Programming) brings cross-cutting logic like security and logging into focus, cleanly and elegantly. Then comes Data Access & Integration — JDBC, ORM, JMS — handling how your app connects, communicates, and stores data. Finally, the Web layer — Spring MVC, Servlets, and more — turns backend logic into seamless user experiences. Each layer builds on the one below it, forming a flexible, modular, and testable foundation for modern enterprise applications. Spring isn’t just a framework — it’s a complete environment for growth, structure, and innovation. #SpringFramework #Java #SoftwareArchitecture #BackendDevelopment #CleanCode #SpringCore
