Java Spring Framework is an open-source framework that is used for creating enterprise-grade, stand-alone applications that run on the Java Virtual Machine. As useful as it is, Java Spring Framework takes a lot of time and knowledge to set up, and deploy. Spring Boot makes this process easier using autoconfiguration, and an opinionated approach that allows Spring Boot to decide which dependencies and packages are right for your project. Spring Boot helps developers that run on their own without relying on an external web server. [1] On Eclipse, Spring Boot is referred to as Spring Tools Suite. This wikiHow article teaches you how to install Spring Tools Suite.
