About Spring (in my words)

👉 Spring Boot is a powerful framework that includes a number of robust libraries that developers can use to deliever business requirements quickly; these libraries can be quickly imported via Maven or Gradle.
👉 By using Spring Boot, developers can easily create and quickly delivery production grade application - quicker turn-around time closely attributed to being able to use imported modules, allowing more time to focus on the business logic and application rather than technical details (i.e. ldap authentication, sso management, web application and etc).

Take for example that you are instructed to build a new web application.

• The web application must be secured against your company LDAP server.
• Authorization should be role based (casual, analyst, and admin).
• You need a REST API which will trigger some business logic to consume data from 'x' number of sources, process and publish to a database.
• This data should be viewable from the UI.

You could choose to create your own Java classes to handle everything from security, session handling, HTTP servlet classes, JPA implementation and etc. Alternatively, you can simply import certain dependencies such as Spring Security, Spring Web Application, Spring Data JPA, Spring JDBC and etc. Then simply leverage these packages to create your services. Don't worry if you can't see the difference now, we've got plenty of runnable projects in this repository for you to download and review.
