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

Which book do you recommend for spring and spring Boot framework
GITHUB Link - github.com/thinkconstructive/rest-api-spring-boot-demo/tree/master In this tutorial all 4 CRUD REST API operations are implemented using Spring Boot for a particular service. First Spring Boot application is implemented from scratch and then evolved to implement REST API. All CRUD operations are also tested using POSTMAN. Kindly watch the full session and try the implementation with the session to get the complete benefit from this course. Also, please comment here to let me know which next session you want me to upload here. Enjoy learning Spring Boot and REST API. Cheers, Esha

Hi, your explanation and way of Demo, neat and clean, but one doubt. I Updated as C4, but In Delete, if I give C1, C2, C3... its not giving any error, simply deleting which I created C4.

First of all thank you for this wonderful session. This is really helpful to understand the concept of api. I have followed this and created same project but I am facing some issues. Whenever I am trying to create more than 1 vendor with different vendorId using POST from postman the previous vendor details get override. I can see that when I am using GET in postman with different vendorId in URL. The payload or details are same for both different vendors. Also with put it gets update in both vendor details and delete is removing all of the vendors created. Can someone tell me where exactly I am making mistake or this is because we are passing same object body in methods? It will be helpful if you clarify this. Thanks
The same code for CloudVendorAPIService works on Intellij IDE but does not work in Eclipse IDE. Any reason..?? Or do we need to change the code..? What changes we need to do in Eclipse..??
Hi ma'am I have followed the same steps. But in this post,put and delete operation, in the postman it's showing i have created,updated and deleted successfully. But when I try to retrieve the data using get, it's not shoing the updated details. Only showing the previous data. Why is it like that?
thanks maam
