A common misconception: Spring is not the same as Spring Boot

Many people use the terms Spring and Spring Boot interchangeably, but beware: they’re not the same! When people use the word Spring, they usually refer to the Spring Framework. Spring Boot is actually more of an extension of the Spring framework. Our Spring trainer Patrick Hancke explains the difference in the video on the right.

Spring Boot is a tool that makes developing web applications and microservices with the Spring Framework a lot easier for Java developers. While the Spring framework focuses on providing flexibility, Spring Boot aims to shorten the code length and allows you to build a stand-alone application with minimal or zero configurations.

Spring boot is widely used to develop REST APIs, whereas the Spring Framework is mostly used for building applications. You can read more about Spring Boot in Spring's documentation.



What is Spring used for?

For developing web applications

Spring is a lightweight application development framework, so it’s no surprise that it’s often used to develop web applications.

For securing web applications

You can implement Spring Security in your projects to protect the web applications you’re building.

For handling long running jobs

Spring Batch provides functions which are essential in processing large volumes of records.

For handling external resources

With Spring Integration, you can integrate external systems via declarative adapters within Spring-based applications.

For standalone Java projects

Spring containers can be run stand-alone with Spring Boot, which makes it easy to create production-grade Spring based applications.
