In this tutorial, we\u2019ll take a look at Spring Boot and see how it\u2019s different from the Spring framework. We\u2019ll also discuss various features offered by Spring Boot.<\/p>\n

What is the Spring Boot?<\/h3>\n

Spring is a powerful framework when it comes to developing enterprise-level applications. It provides us with features like dependency injection along with supporting many other framework extensions.<\/p>\n

Still, there\u2019s a lot of configurations and boilerplate code involved. For instance, for every Spring MVC application, we\u2019ll be configuring the DispatcherServlet<\/em>, InternalResourceViewResolver<\/em>, and a lot of other components.<\/p>\n

Spring Boot is an extension over the Spring framework and enables us to quickly bootstrap a production-ready Spring application.<\/strong><\/p>\n

It is extremely powerful and offers a wide range of features.<\/p>\n

Spring Initializr:<\/h3>\n

We can use the Spring Initializr<\/a> website to quickly download a Spring Boot application template with needed dependencies:<\/p>\n

In the dependencies section, we can add the Spring Boot starter dependencies we need for our application.<\/strong> For instance, we can search and include the Spring Web Starter<\/em> if we are developing a web application.<\/p>\n

All Spring Boot applications have a parent section defined in their POM<\/em> file:<\/strong><\/p>\n

The parent POM<\/em> manages the version of the child dependencies all at once.<\/strong> And so, we can omit version tags for each child dependency. It also defines default configurations for several plugins.
