Java REST API with Spring Boot Tutorial | REST API CRUD Implementation 

Let us learn how to build Java REST API with Spring Boot in this tutorial.
Some key Spring Boot annotations which are discussed in the session are - @SpringBootApplication , @RestController , @RequestBody , @RequestMapping , @GetMapping , @PostMapping , @PutMapping , @DeleteMapping .
Default Data exchange format is used is JSON.
In this session we will learn how to create REST APIs using Spring Boot from the beginning. Here we will first create a simple Spring Boot Application using Spring Initializer and after that will write code for to make it work as Spring Boot REST API. Finally, REST API testing with Postman tool will be demonstrated. Here Create, Read, Update and Delete - All 4 REST API CRUD operations are implemented in this session with the help of Spring Boot. This will be a Simple Spring Boot REST API application which will support CRUD operations. All the CRUD operations will be tested with the help of Postman tool.
A complete Spring Boot REST API project for Cloud Vendor Information Service is developed in this course, hence keep your system ready for building all 4 CRUD operations in just one tutorial.
This is a Spring Boot with REST API beginners course, where Spring Boot Application is build from scratch, hence feel free to attend this.
Some Key points for REST API -
REST APIs also called as RESTful APIs
REST = Representational State Transfer
API = Application Programming Interface
REST is a set of architectural constraints, not a protocol or a standard. API developers can implement REST in a variety of ways
A REST API is an application programming interface that follows the constraints of REST architectural style and allows for interaction with RESTful web services
REST APIs work over HTTP
Delivers information using any one of the following formats -
JSON (Most popular) , Text , HTML , XML , Javascript and more
Spring Boot Key points -
Easily create stand-alone, production-grade Spring based Applications
Tomcat, Jetty are embedded
Provides starter dependencies
Automatically configure Spring and third party libraries
Provides production ready features such as health checks, metrics, etc.
No code generation, No XML configuration
