In contrast, the spring boot can allow the development of applications that as standalone.

After learning about the difference between spring and spring boot, we will explore what is spring and spring boot in brief. The comparison of spring vs spring boot will be done based on various aspects such as key features, use, types of application development, and a lot more in the coming sections.

What is a Spring in Java?

Spring is a framework developed for the Java programming language. This is also called the framework since it is used by various frameworks such as JSP, Struts, etc. It is known for dependency Injection. The benefit of the spring is that it is effective in all layers of the development of the application. 

Spring framework is known for being lightweight. It is a collection of sub-frameworks. There are various modules in the spring framework:

  • Spring AOP
  • Spring Test
  • Spring ORM
  • Spring JDBC
  • Spring MVC
  • Spring Security

What is a Spring Boot?

Spring boot is also a framework built as a module of the spring framework. Standalone applications can be developed with minimal configuration. Among various benefits of spring boot, it does not need deployment of WAR files, is easier to launch, XML configuration is not required, etc. 

The characteristic of a spring boot is that everything in it is auto-configured. Various stater dependencies are offered by spring-boot: 

  • Spring-boot-starter-data-jpa
  • Spring-boot-starter-security
  • Spring-boot-starter-aop
  • Spring-boot-starter-web
  • Spring-boot-starter-thyme-leaf
  • Spring-boot-starter-mail
  • Spring-boot-starter-web-services
  • Spring-boot-starter-test

  • The Spring Boot is created on top of the conventional spring framework. Spring Boot provides all the features of spring and this is quite easier to use than spring whereas the spring is an open-source and lightweight framework which allows Java EE 7 developers to build quite simple, reliable, and scalable enterprise applications.

  • The Spring is a lightweight application framework that provides support to various frameworks such as Hibernate, Struts, JSP, etc. Rod Johnson wrote the first version of the Spring framework in 2002 and the framework was first released in 2003 under the Apache license that has version 2.0.

  • The Spring Boot is created on top of the conventional spring framework. This framework provides all the features of spring and is quite easy to use than spring. The Spring Boot is a Java-based framework used to create a microservice and it makes a production-ready application in very less time.

  • No, we cannot learn Spring boot without Spring because Spring Boot is built on Spring and it is not possible to use Spring Boot without Spring at all. However, it is recommended that we start with Spring Boot and then gradually learn the essential steps of Spring.

  • Spring Boot is not meant to be a replacement for Spring; even, it is created to make working with it faster and quite easier. As a result, most of the modifications required for migrating an application are related to configuration. For the most part, the custom controllers and other components will remain unchanged.
