Difference between Spring and Spring Boot

Spring
 Spring Boot
Spring Framework is a widely used Java EE framework for building applications.Spring Boot Framework is widely used to develop REST APIs, usually for microservices.
It aims to simplify Java EE development that makes developers more productive.It aims to shorten the code length and provide the easiest way to develop Web Applications. That's the reason we often tell it provides production ready code.
The primary feature of the Spring Framework is dependency injection.The primary feature of Spring Boot is Autoconfiguration. It automatically configures the classes based on the requirement.
It helps to make things simpler by allowing us to develop loosely coupled applications.It helps to create a stand-alone application with less configuration.
The developer writes a lot of code (boilerplate code) to do the minimal task.It reduces boilerplate code.
To test the Spring project, we need to set up the sever explicitly.Spring Boot offers embedded server such as Tomcat, Jetty etc.
It does not provide support for an in-memory database.It offers several plugins for working with an embedded and in-memory database such as H2.
Developers manually define dependencies for the Spring project in pom.xml.Spring Boot comes with the concept of starter in pom.xml file that internally takes care of downloading the dependencies JARs based on Spring Boot Requirement.
