Spring 5.0 By Example

Spring Boot

Spring Boot was released in 2014. The idea behind this project was to present a way to deploy the web application outside of any container, such as Apache Tomcat, Jetty, and so on. The benefit of this kind of deployment is the independence from any external service. It allows us to run the web applications with one JAR file. Nowadays, this is an excellent approach because this forms the most natural way to adopt DevOps culture.

Spring Boot provides embedded servlet containers, such as Apache Tomcat, Jetty, and Undertow. It makes the development process more productive and comfortable when testing our web applications. Also, customizations during configuration are allowed via a configuration file, or by providing some beans.
