Description

In this course, you will learn how to build REAL TIME REST APIs using Spring boot.

Well, we will follow the Real-time industry-standard project development approach in this course.

SpringBoot ?

Spring Boot is an open source, microservice-based Java web framework. The Spring Boot framework creates a fully production-ready environment that is completely configurable using its prebuilt code within its codebase

JPA?

Spring Boot JPA is a Java specification for managing relational data in Java applications. It allows us to access and persist data between Java object/ class and relational database. JPA follows Object-Relation Mapping (ORM). It is a set of interfaces

H2 Database ?

H2 database is an open source, embedded and in memory relational database management system. It is written in Java and provides a client/server application. It stores data in system memory instead of disk. Once program is closed, data is also lost

Lombok ?

What is Lombok. Project Lombok (from now on, Lombok) is an annotation-based Java library that allows you to reduce boilerplate code. Lombok offers various annotations aimed at replacing Java code that is well known for being boilerplate, repetitive, or tedious to write
