Spring Boot is an open-source Java-based framework designed for quickly setting up production-ready applications by automating configuration, thus allowing developers to focus more on logic than setup. It features an embedded server, reducing the need for pre-setup containers and avoiding excessive boilerplate code, while also enabling different environment profiles and simplified dependency management. To get started, prerequisites include Maven or Gradle, Java (recommended version 1.8 or greater), and a basic understanding of HTTP methods and Spring MVC.

2. Java (Recommended1.8versionorgreaterversion) –https://maven.apache.org
3. IDE (Itcan be anythinglike sts,eclipse,IntelliJ,etc.butthisprojectexplainedwitheclipse asIDE).
4. Basic understandingof HTTP methods i.e.GET,POST,PUT, DELETE, etc.
5. Basic understandingof SpringMVC.
Advantages of Spring Boot
1. Container fewer Deployments: In Spring Boot instead of deploying application in containers (like
tomcat, JBoss, etc.) it had embedded tomcat, as a result.
a) Pre-setupof container&configurationforeachenvironmentlikedevelopment,production,etc.isnot
required. When the application is ready for deployment we only need to find an environment that is
capable of running the correct version of java that our application runs.
b) Forapplicationtoworkwe needtoprovidesome deploymentdescriptivesothe containerunderstands
how to deploy & serve up our application which is done in XML. but in Spring Boot no longer needed
deployment descriptive & web.xml file as Spring Boot contains an embedded container.
2. Avoids writing lots of boilerplate code, Annotations.
3. We can create profiles for different environments like development, production, etc.
4. Removed need to specify a version for dependencies in pom.xml file & bother about versions
compatibility for different libraries & frameworks in an application.
