Description

Introduction

Spring Boot is a widely used Java-based framework that simplifies the process of building cloud-native, production-ready applications. It is built on top of the Spring Framework, designed to provide a set of tools and conventions to streamline the development of Java applications. Spring Boot eliminates the need for extensive configuration and boilerplate code, enabling developers to focus on building application logic. It provides a fast and efficient way to create web applications, RESTful services, microservices, and more, with integrated support for key features like embedded servers, security, and persistence. Spring Boot’s popularity stems from its ability to integrate seamlessly with cloud platforms, offering scalability and flexibility for modern applications.

Prerequisites

• Basic understanding of Java programming and object-oriented concepts.
• Familiarity with the Spring Framework and its core components (e.g., Spring MVC, Spring Data).
• Knowledge of web development concepts (e.g., HTTP, REST, APIs).
• Understanding of dependency injection and inversion of control (IoC) patterns.
• Basic knowledge of Maven or Gradle for managing dependencies and building projects.
• A working development environment (e.g., IntelliJ IDEA, Eclipse, or VS Code).
• JDK (Java Development Kit) installed on your machine.
