SpringBoot React Oracle CRUD Example

Tutorial: SpringBoot + React + Oracle: Build CRUD Application with SpringBoot React.js Example

In the tutorial, I introduce how to build an “SpringBoot React.js CRUD Oracle Example” project with the help of SpringData JPA for POST/GET/PUT/DELETE requests with step by step coding examples:

– SpringBoot project produces CRUD RestAPIs with Oracle database using the supporting of Spring Data JPA.
– React.js project will consume the SpringBoot CRUD RestAPIs by Ajax then show up on Reactjs component’s views.

– I draw a fullstack overview Diagram Architecture from React.js Frontend to Oracle database through SpringBoot RestAPI backend.
– Develop SpringBoot CRUD RestAPIs with the supporting of SpringWeb Framework.
– Implement Reactjs CRUD application with Ajax fetching APIs to do CRUD request (Post/Get/Put/Delete) to SpringBoot Backend APIs.
– I create a testsuite with a number of integrative testcases with CRUD RestAPI requests from Reactjs to do CRUD requests to SpringBoot RestAPIs Server and save/retrieve data to Oracle database.

<ul>
<li>We build a backend: SpringBoot CRUD Application with Oracle that provides RestAPIs for POST/GET/PUT/DELETE data entities and store them in Oracle database.</li>
<li>We implement React.js CRUD Application that use Ajax to interact (call/receive requests) with SpringBoot CRUD application and display corresponding data in Reactjs Component.</li>
</ul>

I build a SpringBoot project that handle all Post/Get/Put/Delete requests from RestClient and do CRUD operations to Oracle database to save/retrieve/update and delete entity from Oracle and returns back to Restclient the corresponding messages.

We build a SpringBoot project with 2 layers:
– SpringJPA Repository is used to interact with Oracle database by a set of CRUD operations.
– RestController layer is a web layer for SpringBoot project, it will directly handle all incomming requests and do the corressponding responses to the calling client.

– Reactjs CRUD Application is designed with 2 main layers:
<ul>
<li>React.js components let you split the UI into independent, reusable pieces, and think about each piece in isolation.</li>
<li>Ajax is used by Reactjs component to fetch (post/put/get/delete) data from remote restapi by http request</li>
</ul>

Reactjs CRUD Application defines 5 components:

<ul>
<li><code>Home.js</code> is used serve as the landing page for your app.</li>
<li><code>AppNavbar.js</code> is used to establish a common UI feature between components.</li>
<li><code>CustomerList.js</code> is used to show all customers in the web-page</li>
<li><code>CustomerEdit.js</code> is used to modify the existed customer</li>
<li><code>App.js</code> uses React Router to navigate between components.</li>
</ul>

Reactjs delete data:

-> Delete a customer Adam with id=2, after successfully, check the customer list again:
