springbootrestapiexample

A small java application showing Spring Boot, MySQL, JPA, Hibernate Restful CRUD API

The Spring Framework is an application framework and inversion of control container for the Java platform.

The framework's core features can be used by any Java application, but there are extensions for building web

applications on top of the Java EE platform.

1. Spring Boot is a Spring framework module which provides RAD (Rapid Application Development) feature to the Spring framework.

It is highly dependent on the starter templates feature which is very powerful and works flawlessly.

2. MySQL database as backend

3. JPA - The Java Persistence API is a Java application programming interface specification that describes

the management of relational data in applications using Java Platform, Standard Edition and Java Platform, Enterprise Edition.

4. Hibernate ORM is an object-relational mapping tool for the Java programming language.

It provides a framework for mapping an object-oriented domain model to a relational database.
