What is the difference between Spring MVC and Spring Boot?

Spring MVC and Spring Boot are both parts of the Spring Framework, but they serve different purposes and are used in different contexts. Here’s a breakdown of their key differences:

1. Spring MVC

• Purpose:
  • Provides a framework for building web applications using the Model-View-Controller (MVC) architecture.
  • Focuses on handling HTTP requests, views, and form submissions.
• Features:
  • Supports fine-grained control over configuration.
  • Primarily used for building traditional web applications.
  • Requires configuration of components like view resolvers, message converters, etc.
• When to Use:
  • When you need full control over web components and complex web applications with custom configurations.

2. Spring Boot

• Purpose:
  • A rapid application development framework that simplifies the setup of Spring-based applications with minimal configuration.
  • Provides auto-configuration and convention over configuration for common use cases.
• Features:
  • Provides a more opinionated approach to web development.
  • Reduces the need for manual configuration.
  • Includes embedded servers like Tomcat, Jetty, or Undertow, allowing for standalone Spring applications without needing external server setup.
• When to Use:
  • When you need a fast, opinionated, and minimal configuration setup for building web applications or microservices.
  • Ideal for quick prototyping and getting a basic Spring application up and running quickly.

Key Differences:

Summary:

• Spring MVC offers detailed control over web development with manual configuration.
• Spring Boot provides a streamlined approach with auto-configuration and an embedded server for rapid development.
