Building a Hello World Web Application with Spring MVC and JSP
🚀 Take Your Java Skills to the Next Level!
SUBSCRIBE TO RAM N JAVAThe Basics of Spring MVC
Welcome back to Ram N Java! Today, we're diving into the heart of web development with Spring Boot by creating a classic "Hello World" application. We'll be using Spring MVC (Model-View-Controller), which is the standard design pattern for building flexible and loosely coupled web applications in Java. It separates the business logic (Model), the user interface (View), and the user input (Controller).
Why Use JSP with Spring Boot?
While modern web development often uses frontend frameworks, JavaServer Pages (JSP) remains a powerful and widely used technology for server-side rendering. JSP allows you to embed Java code into HTML pages, making it easy to display dynamic data. In this guide, we'll configure Spring Boot to recognize and serve these JSP files as our "View" layer.
Key Steps to Your First Web App
- Project Setup: Start with Spring Initializr and include the 'Spring Web' dependency.
- Controller Creation: Use the
@Controllerannotation to handle incoming web requests. - View Resolver: Configure your application properties to tell Spring where to find your JSP files (usually in
/WEB-INF/jsp/). - Running the App: Fire up the embedded Tomcat server and view your result in the browser!
