Spring Boot vs Spring MVC – Key Differences

 🆚 Spring Boot vs Spring MVC

Feature Spring MVC Spring Boot

Definition A web framework built on the Spring Framework for building web applications (uses Servlet API, annotations, etc.) A complete framework that simplifies Spring application development by adding auto-configuration and embedded servers

Configuration Requires manual configuration of XML or Java-based settings (e.g., dispatcher, view resolvers, etc.) Comes with automatic configuration and sensible defaults

Setup Time Slower; needs setup of external server (like Tomcat) and configuration files Faster; comes with embedded server (Tomcat, Jetty, or Undertow)

Dependencies Management Manual dependency management in pom.xml or build.gradle Manages most dependencies using Spring Boot Starters

Project Type Used for traditional enterprise apps or specific web modules Ideal for microservices and REST APIs

Learning Curve Requires understanding of Spring Core and extensive config Easier for beginners with opinionated setup

Command Line Support Not built-in Can be launched with a single command: java -jar app.jar

Development Speed Slower due to more setup Much faster development cycle

Use of Spring Boot Internally N/A Spring Boot includes and uses Spring MVC internally for web apps

Community and Popularity Still used for complex, legacy apps Very popular for modern web & cloud apps


🧠 Quick Definitions

🔹 Spring MVC

A web framework that uses a Model-View-Controller architecture. It is a part of the larger Spring Framework. You must configure it manually.


🔹 Spring Boot

A rapid application development framework built on Spring. It uses Spring MVC internally but adds auto-configuration, embedded servers, and starter dependencies to reduce boilerplate.


✅ When to Use What?

Use Case Recommended

Traditional enterprise applications Spring MVC

Microservices and REST APIs Spring Boot

You want full control over config Spring MVC

You want to start quickly with minimal setup Spring Boot

You’re building cloud-native or container-based apps Spring Boot


📝 Summary

Spring MVC is the web framework part.


Spring Boot is the full package that simplifies building and running Spring apps, including those using Spring MVC.
