In this tutorial, let's learn how to build Java REST API with Spring Boot.
Some important Spring Boot annotations discussed in the session are – @SpringBootApplication , @RestController , @RequestBody , @RequestMapping , @GetMapping , @PostMapping , @PutMapping , @DeleteMapping .
The standard format for data exchange is JSON.
In this session, we will learn how to create REST APIs with Spring Boot from scratch. Here we will first create a simple Spring Boot application using Spring Initializer and then write code to make it work as Spring Boot REST API. Finally, REST API testing with the Postman tool will be demonstrated. Here Create, Read, Update and Delete – All 4 REST API CRUD operations are implemented in this session using Spring Boot. This will be a Simple Spring Boot REST API application that supports CRUD operations. All CRUD operations are tested using the Postman tool.
This course develops a complete Spring Boot REST API project for Cloud Vendor Information Service, so you can keep your system ready to build all four CRUD operations in just one tutorial.
This is a Spring Boot with REST API beginners course, building the Spring Boot application from scratch, so feel free to attend.

Some key points for REST API –
REST APIs are also called RESTful APIs
REST = Representative State Transfer
API = Application Programming Interface
REST is a set of architectural constraints, not a protocol or standard. API developers can implement REST in several ways
A REST API is an application programming interface that follows the constraints of the REST architecture style and enables interaction with RESTful web services
REST APIs work over HTTP
Provides information using one of the following formats:
JSON (Most Popular), Text, HTML, XML, Javascript and more

Spring Boot Key Points –
Easily create stand-alone, production-quality spring-based applications
Tomcat and Jetty are embedded
Provides starter dependencies
Automatically configure Spring and third-party libraries
Provides production-ready features such as health checks, statistics, etc.
No code generation, no XML configuration
