You can read my article "Why SpringBoot?" which exactly describes what you want to know. http://sivalabs.in/2016/03/why-springboot/ – K. Siva Prasad Reddy Sep 15 '16 at 04:57

First of all spring boot isn't a framework. https://springhow.com/spring-boot-and-spring/ – Raja Anbazhagan Aug 09 '20 at 19:43

Two best things about Spring Boot are
- It's pure Java. You can run it without XML
- Built-in tomcat app server. You can run it without setting up an app server
So it's both correct and simple to use now. I recommend trying one of the many github examples, the one I want to recommend is https://spring.io/guides/gs/rest-service/ - just download the files and you can run it directly with gradle.

The main points are the following (my opinion, which would imply that this question should be closed):
- spring-boot is the java answer to microservices : why-spring-is-winning-the-microservices-game
- somewhat encourages the 12-factors
- you can have a simple working example with ~ 10 lines of code.
- you can launch the app from a jar (with an embedded container) or deployed as a war, with the same spring configuration. Configure once, deploy/run anywhere :)
- spring-boot
autoconfiguresmany things for you: the spring configuration is much simpler - debugging the application is as simple as executing a main method
- It's fun
- many great spring projects integrate nicely with sring-boot:
spring-cloud,spring-data... - Another SO answer: Advantage of Spring Boot
What Spring says:
Spring Boot aims to make it easy to create Spring-powered, production-grade applications and services with minimum fuss. It takes an opinionated view of the Spring platform so that new and existing users can quickly get to the bits they need.
...
The primary goals of Spring Boot are:
- To provide a radically faster and widely accessible ‘getting started’ experience for all Spring development
- To be opinionated out of the box, but get out of the way quickly as requirements start to diverge from the defaults
- To provide a range of non-functional features that are common to large classes of projects (e.g. embedded servers, security, metrics, health checks, externalized configuration)
