Getting Started Building an Application with Spring Boot

For building or developing applications, the Spring framework is considered to be the most widely used Java EE  framework. You can define the needs of your project during the initialization process, during which you choose among multiple starter dependencies—called Spring Starters—that cover typical use cases. You run Spring Boot Initializr by filling out a simple web form, without any coding. In the above example, I have used @RequestMapping annotation to map requests to the controller method.

  • You should also see a much smaller file named myproject-0.0.1-SNAPSHOT.jar.original in the target directory.
  • This feature significantly reduces the development time and effort required for setting up a Spring application.
  • Understanding the project structure and configuration is crucial for organizing and customizing your Spring Boot application.
  • Path such as JPA, Security, Spring, and so on, to name a few.
  • These features work together to provide you with a tool that allows you to set up a Spring-based application with minimal configuration and setup.

You can shortcut the steps below by going to and choosing the “Web” starter from the dependencies searcher. Doing so generates a new project structure so that you can start coding right away. You can clearly see org.springframework.boot.autoconfigure beans. The main() method uses Spring Boot’s method to launch an application. This web application is 100% pure Java and you did not have to deal with configuring any plumbing or infrastructure. You can use this pre-initialized project and click Generate to download a ZIP file.

Learn What You Can Do with Spring Boot

For example, if you want to get started using Spring and JPA for database access, include the spring-boot-starter-data-jpa dependency in your project, and you are good to go. You can use Spring Boot to create stand-alone Java applications that can be started using java -jar or more traditional WAR deployments. We also provide a command-line tool that runs Spring scripts. Hopefully, this section provided some of the Spring Boot basics and got you on your way to writing your own applications. If you are a task-oriented type of developer, you might want to jump over to and follow some of the getting started guides that solve specific “How do I do that with Spring? We also have Spring Boot-specific “How-to” reference documentation.

what is spring boot

Choose an Integrated Development Environment (IDE) that suits your preferences. Popular choices include IntelliJ IDEA, Eclipse, and Visual Studio Code. Configure your IDE to use the installed JDK, ensuring a smooth development experience. Can simply build the application jar and run the application with no need to customize the deployment. Spring Boot allows us to externalize our configuration so that we can work with the same application in different environments. The application uses YAML files to externalize configuration.

Spring Boot can use dependencies that are not going to be used in the application. DigitalOcean makes it simple to launch in the cloud and scale up as you grow – whether you’re running one virtual machine or ten thousand.

For web applications Spring provides
Spring MVC which is a widely used module of spring which is used to create scalable web applications. But main disadvantage of spring projects is that spring boot lessons configuration is really time-consuming and can be a bit overwhelming for the new developers. Making the application production-ready takes some time if you are new to the spring.

So in theory one could have a Spring MVC project packaged as a Spring Boot application. Both can be classified as Spring frameworks however the scale of Spring Boot encompasses many types of Spring frameworks. While, Spring MVC on the other hand specifies the design of the framework.
