Without repeating the same thing in previous answers  I m writing this answer for the people who are looking to starting a new project and don t know which is the best framework to startup your project  If you are a beginner to this framework the best thing I prefer is Use spring boot with STS  Spring Tool Suite   Because it helps a lot  Its do all configurations on its own  Additionally  use Hibernate with spring-boot as a database framework  With this combination  your application will be the best  I can guarantee that with my experiences    Even this is one of the best frameworks for JEE in present  this is gonna die in the near future  There are lightweight alternatives coming up  So keep updated with your experience don t stick to one particular framework  The best thing is being fluent in concepts  not in the frameworks

Spring MVC and Spring Boot are exist for the different purpose  So  it is not wise to compare each other as the contenders   What is Spring Boot   Spring Boot is a framework for packaging the spring application with sensible defaults  What does this mean   You are developing a web application using Spring MVC  Spring Data  Hibernate and Tomcat  How do you package and deploy this application to your web server  As of now  we have to manually write the configurations  XML files  etc  for deploying to web server   Spring Boot does that for you with Zero XML configuration in your project  Believe me  you don t need deployment descriptor  web server  etc  Spring Boot is magical framework that bundles all the dependencies for you  Finally your web application will be a standalone JAR file with embeded servers   If you are still confused how this works  please read about microservice framework development using spring boot   What is Spring MVC   It is a traditional web application framework that helps you to build web applications  It is similar to Struts framework   A Spring MVC is a Java framework which is used to build web applications  It follows the Model-View-Controller design pattern  It implements all the basic features of a core spring framework like Inversion of Control  Dependency Injection   A Spring MVC provides an elegant solution to use MVC in spring framework by the help of DispatcherServlet  Here  DispatcherServlet is a class that receives the incoming request and maps it to the right resource such as controllers  models  and views   I hope this helps you to understand the difference

Spring MVC is a complete HTTP oriented MVC framework managed by the Spring Framework and based in Servlets  It would be equivalent to JSF in the JavaEE stack  The most popular elements in it are classes annotated with  Controller  where you implement methods you can access using different HTTP requests  It has an equivalent  RestController to implement REST-based APIs  Spring boot is a utility for setting up applications quickly  offering an out of the box configuration in order to build Spring-powered applications  As you may know  Spring integrates a wide range of different modules under its umbrella  as spring-core  spring-data  spring-web  which includes Spring MVC  by the way  and so on  With this tool you can tell Spring how many of them to use and you ll get a fast setup for them  you are allowed to change it by yourself later on     So  Spring MVC is a framework to be used in web applications and Spring Boot is a Spring based production-ready project initializer  You might find useful visiting the Spring MVC tag wiki as well as the Spring Boot tag wiki in SO

Spring MVC is a sub-project of the Spring Framework  targeting design and development of applications that use the MVC  Model-View-Controller  pattern  Spring MVC is designed to integrate fully and completely with the Spring Framework and transitively  most other sub-projects   Spring Boot can be understood quite well from this article by the Spring Engineering team  It is supposedly opinionated  i e  it heavily advocates a certain style of rapid development  but it is designed well enough to accommodate exceptions to the rule  if you will  In short  it is a convention over configuration methodology that is willing to understand your need to break convention when warranted

Using spring boot you will no need to build configuration  This will have done automatically when you create project  If you use spring MVC you need to build configuration yourself  It is more complicated  but it is crucial

Spring MVC and Spring Boot are well described in other answers  and so without repeating that  let me jump straight to the specifics  Spring Boot and Spring MVC are not comparable or mutually exclusive  If you want to do web application development using Spring  you would use Spring MVC anyway  Your question then becomes whether to use Spring Boot or not   For developing common Spring applications or starting to learn Spring  I think using Spring Boot would be recommended  It considerably eases the job  is production ready and is rapidly being widely adopted   I have seen sometimes beginners asking this question because in STS  Spring Tool Suite  there are two wizards  one for creating a Spring Boot project  and another for creating a Spring MVC project  So  my recommendation would be to create a Spring Boot project and choose Web as a module in that

Think this way   Spring MVC is a web based framework to implement the MVC architecture   Spring Boot is a tool oriented to the programmer  Programmer must focus on programming and tool must focus on configurations  So we don t need to wast our time configuring a bunch of xml to make a simple  Hello world

Here is some main point which differentiate Spring  Spring MVC and Spring Boot     Spring     Main Difference is  Test-ability   Spring come with the DI and IOC  Through which all hard-work done by    system we don t need to do any kind of work like  normally we define object     of class manually but through Di we just annotate with  Service or   Component - matching class manage those   Through  Autowired annotation we easily mock   it at unit testing time  Duplication and Plumbing code  In JDBC we writing same code multiple time   to perform any kind of database operation Spring solve that issue through   Hibernate and ORM  Good Integration with other frameworks  Like Hibernate  ORM  Junit  amp     Mockito    Spring MVC   Spring MVC framework is module of spring which provide facility HTTP oriented web application development  Spring MVC have clear code separation on input logic controller   business logic model   and UI logic view   Spring MVC pattern help to develop flexible and loosely coupled web applications  Provide various hard coded way to customise your application based on your need    Spring Boot     Create of Quick Application so that  instead of manage single big web   application we divide them individually into different Microservices which have their own scope  amp  capability  Auto Configuration using Web Jar   In normal Spring there is lot of     configuration like DispatcherServlet    Component Scan  View Resolver  Web  Jar  XMLs   For example if I would like to configure datasource  Entity     Manager     Transaction Manager Factory   Configure automatically when it s not available   using class-path  Comes with Default Spring Starters  which come with some default Spring     configuration dependency  like Spring Core  Web-MVC  Jackson  Tomcat    Validation  Data Binding  Logging   Don t worry about versioning issue as well     Evolution like   Spring -  Spring MVC -  Spring Boot  So newer version have the compatibility of old version features   Note   It doesn t contain all point

SpringBoot is actually pre configured  that reduced boiler configuration and providing easiest or quick way to start your application   SpringBoot take the headache of configuration from developer to it s own self rather than Spring   Implicitly SpringBoot is based on Spring framework concept like bean  controller   services  jpa etc   You can say that SpringBoot is a wrapper of Spring   In SpringBoot by default port of Server is 8080 but if you want to change then go to your application properties and write  server port   8084

To add my once cent  Java Spring is a framework while Java Spring Boot is addon to accelerate it by providing pre-configurations and or easy to use components  It is always recommended to have fundamental concepts of Java Spring before jumping to Java Spring Boot
