What is difference between spring and spring boot

Posted By : Simran Ahuja | 27-Nov-2020

Spring Framework

Spring is one of the most widely used Java EE Frameworks used for building applications. For the Java platform, the Spring framework provides very elaborate programming and configuration model. It aims in simplifying the Java EE development and helps the developers to be more productive in the work environment. It can be used at various kinds of deployment platforms. It takes into account the rising needs of today’s businesses and strives to fulfill each of them.

Unlike other frameworks, Spring focuses on several areas of an application by providing a wide range of features.

One of the major features of the Spring framework is its dependency injection. It simplifies things by enabling us to develop loosely coupled applications.

Spring Boot

Spring framework focuses on providing flexibility whereas Spring Boot aims to shorten the length of code. In short, it provides you with the easiest way to develop an efficient web application. Spring Boot shortens the time involved in the development of an application using annotation configuration and default codes. It also helps to create a stand-alone application with minimal or you may say almost zero-configuration.

Autoconfiguration feature can automatically configure a class based on the requirements thus being referred to as a very special feature in Spring Boot. Let us take a quick look at various features and benefits of these frameworks:

Benefits of the Spring Framework

•    It can be used at every layer of implementation of an application development

•    Considering its POJO model, thus it is a very lightweight framework.

•    It allows loose coupling and very easy testability.

•    It supports declarative programming for programmers.

•    It is very efficient and capable of eliminating the formation of singleton and factory classes.

•    It supports both XML and annotation configurations.

•    It provides middleware services.

Despite having several benefits in the Spring framework, what led to the emergence of the so-called Spring Boot?

Spring Boot helps in the easy usage of the Spring Framework by simplifying it to a very great extent. Spring providing a  loosely coupled application — this is a great feature. However, when there are several loosely coupled blocks, keeping track of them becomes a  very tedious and messy task. This is where Spring Block comes into the picture and helps in simplifying things by offering no configuration feature. It helps you get started with minimal effort and even provides externalized configuration also.


Benefits of Spring Boot

•    Spring Boot doesn’t require you to deploy any WAR files.

•    It creates stand-alone applications and good applications.

•    It helps embed Tomcat, Jetty, or Undertow directly.

•    It doesn’t any require XML configuration.

•    It aims in reducing the LOC.

•    It offers production-ready features and is very productive.

•    It is easier to launch.

•    Easier customization and management.


Therefore, Spring Boot is the  Spring-based production-ready project initializer. With features like auto-configuration, it saves you from writing all lengthy code and helps you to avoid unnecessary configuration.


While the Spring Framework offers you features like dependency injection, IOC, and handles transactions, it also acts as a foundation for all other Spring frameworks. The best example of this is Spring boot. Spring Boot uses the Spring Framework as a foundation and improvises on it for good. It simplifies Spring dependencies and runs applications straight from the command line. It also doesn’t require any application container. Spring Boot mostly helps in monitoring several components and configures them externally and efficiently.


All in all, the Spring framework has made a  very significant contribution and continues to do so well. With the many features mentioned above, the Spring framework is always a very great choice for all developers. However, it is highly beneficial when used alongside Spring Boot. The added advantages that come with Spring Boot are of excellent great value to the developers as they offer completion of projects with minimal effort for developers. To all the problems that arise from the Spring framework, Spring Boot is a very solution.
