Configure Spring MVC without web.xml using WebApplicationInitializer

📘 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

🌱 Bean Scopes in Spring Spring supports multiple bean scopes such as singleton, prototype, request, session, and application. The singleton scope creates one shared instance per container, while prototype generates a new instance each time. Web scopes like request and session manage user-specific data efficiently in web applications. 🌐 #SpringFramework #SpringBoot #Java #BackendDevelopment #BeanScopes

☀️ 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

Good APIs are like ogres: they have layers. But while an ogre hides its softness behind a rough shell, an API should do the opposite: friendly and polished on the outside, with the complex machinery hidden beneath. In my new post, I look at how Spring MVC and WebMvc.fn illustrate this principle of layered API design, and why higher layers should still let you reach the lower ones. https://lnkd.in/eh6duNpV #Java #Kotlin #APIDesign #SpringFramework

Honestly, I don’t get why no one really talks about JSP & Servlets in the Java community anymore. I mean, Spring itself is literally built on top of the Servlet API yet most Spring Boot roadmaps don’t even mention learning them. Even if you’re not going to use them directly, understanding how a request is built and processed can really help when you’re debugging or trying to understand what’s happening behind the scenes. What do you think? #Java #SpringBoot #SpringFramework #JSP #Servlets

I stopped memorizing API terms and asked a simpler question “Why do APIs even exist?” That led me into a deep dive from first principles, REST, HTTP, MVC, caching, and all the invisible patterns behind modern web systems. I’ve summed it up in a concise REST API Handbook that explains not just how but why APIs work the way they do. (Attached below — I hope it helps someone starting the same journey.)

🔙 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
