What's the difference between Spring Boot and Spring MVC

Spring MVC (Model-View-Controller) is a web framework within the Spring ecosystem that is designed for building traditional, server-side web applications. It follows the MVC design pattern, where:

Model: Represents the application's data and business logic.
View: Represents the user interface, usually created with technologies like JSP, Thymeleaf, or other templating engines.
Controller: Handles user requests, interacts with the model, and returns the appropriate view.
Key Features of Spring MVC:

Configuration: Spring MVC requires detailed configuration, either through XML or Java annotations, to set up the web application context, define controllers, map URLs to methods, and more.
Flexibility: It's highly flexible, allowing developers to pick and choose the components they need, but this flexibility can also lead to complexity in setup and maintenance.
Spring Boot
Spring Boot is an extension of the Spring Framework that simplifies the process of developing new Spring applications by providing a convention-over-configuration approach. It does this by:

Auto-configuration: Spring Boot automatically configures your application based on the dependencies you include. For example, if you include Spring MVC as a dependency, Spring Boot will automatically set up a basic web application without requiring explicit configuration.
Embedded Server: Spring Boot includes an embedded web server (like Tomcat or Jetty), which allows you to run your application as a standalone Java application, without needing to deploy it to an external server.
Opinionated Defaults: Spring Boot comes with sensible defaults out-of-the-box, which makes it easier to get started quickly. It provides pre-configured setups for commonly used components, like security, database access, and REST APIs.
Starter Dependencies: Spring Boot provides starter dependencies, which are pre-defined sets of dependencies for common scenarios. For instance, the spring-boot-starter-web starter brings in all the dependencies needed to create a web application, including Spring MVC, Tomcat, and Jackson.
Key Differences Between Spring Boot and Spring MVC:

Purpose: Spring MVC is specifically for building web applications, while Spring Boot is a framework that simplifies the setup and development of Spring-based applications, including but not limited to web applications.
Configuration: Spring MVC requires manual configuration, while Spring Boot leverages auto-configuration to reduce the need for boilerplate setup.
Deployment: Spring MVC applications typically require deployment to an external server, whereas Spring Boot applications can run independently with an embedded server.
Startup Time: Spring Boot is designed for quick startup and development, making it easier to get a Spring application up and running with minimal effort.
