Difference between Spring MVC and Spring Boot [closed]
Spring MVC and Spring Boot are both part of the Spring framework, but they serve distinct roles and functionalities when building Java applications. The key differences are outlined below:Definition and Purpose:Spring MVC is a framework for building web applications within the Spring ecosystem. It primarily implements design patterns such as Inversion of Control (IoC) and Aspect-Oriented Programming (AOP), and handles HTTP requests in web applications.Spring Boot was designed to simplify developing standalone applications using the Spring framework. It embeds servers like Tomcat, Jetty, or Undertow directly via auto-configuration, eliminating the need to deploy WAR files.Dependency Management:In Spring MVC, you must manually configure all dependencies and libraries, including Spring core, web modules, and database connections.Spring Boot provides "starters" that automatically manage project dependencies. For instance, to build a web application, you only need to add the dependency.Auto-Configuration:Spring MVC requires manual setup of components like DispatcherServlet and WebApplicationContext.Spring Boot leverages extensive auto-configuration, removing manual setup. It automatically configures your application based on JAR files present in the classpath.Embedded Servers:Traditional Spring MVC applications require deployment to an external server, such as Tomcat or Jetty.Spring Boot supports embedded servers, streamlining development and testing. You can start your application simply by running it, without deploying any files.Use Cases:Spring MVC suits developers building applications from the ground up who require fine-grained control.Spring Boot is ideal for developers of all levels, especially for projects needing rapid startup and execution, as well as microservices architecture.Example:Suppose I need to quickly develop a RESTful web service. With Spring Boot, I can achieve this efficiently: add the dependency, create a class with , define route methods, and the application runs without configuring Tomcat.In summary, Spring MVC offers a robust framework for fine-grained web application configuration, while Spring Boot enables rapid development without intricate configurations, making it particularly suitable for microservices architecture and projects requiring quick iterations.
