Java Spring Boot

Using Spring Boot

Java Spring Boot builds scalable web apps with MVC and REST.

Introduction to Spring Boot

Spring Boot is an open-source Java-based framework used to create standalone, production-grade Spring-based applications. It is designed to simplify the development of new Spring applications and helps developers to bootstrap applications quickly.

Setting Up a Spring Boot Project

To start a new Spring Boot project, you can use the Spring Initializr, which allows you to generate a project setup based on your requirements. Choose the dependencies you need, such as Spring Web for RESTful APIs, and download the generated project.

Creating a Simple REST Controller

Spring Boot makes it easy to create RESTful web services. You can define a REST controller using the @RestController annotation. Here's a simple example of a REST controller that handles HTTP GET requests.

Understanding MVC Architecture

Spring Boot applications commonly follow the Model-View-Controller (MVC) architecture, which separates the application into three main logical components:

  • Model: Represents the application's data and business logic.
  • View: Renders the model into a user interface.
  • Controller: Handles input and updates the model and view accordingly.
