Spring BOOT introduction

What is Spring Boot?

Spring Framework is an open-source, enterprise-level framework in Java. It is used to develop standalone, production-grade applications on the Java Virtual Machine (JVM).  
The tool called "Spring Boot" makes the development of web applications and microservices with Spring Framework faster and easier. It allows you to set up a Spring-based application with minimal configuration and setup through three core capabilities: Autoconfiguration, opinionated approach to configuration, and ability to create standalone applications. We can easily create a self-contained HTTP server using embedded Tomcat, Jetty, or Undertow. We can even use the spring-boot-starter-web module to start and run applications quickly.

Rising popularity of Spring Boot

Spring Boot has become the most popular Java web site, adding 14% from last year. Unlike many other frameworks, which focus on only one area, Spring framework provides a wide variety of features addressing the modern business needs via its portfolio projects.

The Spring team created spring Boot to address the complexity of the configuration. It provides flexibility to configure beans in multiple ways, such as XML, Annotations, and JavaConfig. With the increased number of features and complexity, configuring Spring applications becomes tedious and error-prone.
