This tutorial will teach you how to do the full stack development application using Spring boot with React and mongoDB you how to do basic database functions that are CREATE RETIEVE, UPDATE and DELETE using mongoDB Database.
@PostMapping: annotation which used to create new record.
@GetMapping: annotation which used to reads a record.
@RequestMapping: annotation which used to search the record.
@PutMapping: annotation which used to update the existing record.
@DeleteMapping: annotation which used to delete the record.

} Installing React
npx create-react-app front-end
After complete the installation and run the project using following command.
npm start Now you see the React Welcome Page.
After that open the React project into VS code editor.
First Step go to the bootstrap respect website and copy the bootstrap style paste inside the head tag.
After that install the axios by typing the following command
npm i axios Creating a new Component student.jsx Paste the following code
import axios from 'axios';
import {useEffect, useState } from "react";
function Student()
{
//Logic
const [studentid, setId] = useState('');
const [studentname, setName] = useState("");
const [studentaddress, setAddress] = useState("");
const [mobile, setMobile] = useState("");
const [students, setUsers] = useState([]);
useEffect(() => {
(async () => await Load())();
}, []);
async function Load()
{
const result = await axios.get(
"http://localhost:8081/api/v1/student/getall");
setUsers(result.data);
console.log(result.data);
}
async function save(event)
{
event.preventDefault();
try
{
await axios.post("http://localhost:8081/api/v1/student/save",
{
studentname: studentname,
studentaddress: studentaddress,
mobile: mobile
});
alert("Student Registation Successfully");
setId("");
setName("");
setAddress("");
setMobile("");
Load();
}
catch(err)
{
alert("User Registation Failed");
}
}
async function editStudent(students)
{
setName(students.studentname);
setAddress(students.studentaddress);
setMobile(students.mobile);
setId(students._id);
}
async function DeleteStudent(studentid)
{
await axios.delete("http://localhost:8081/api/v1/student/delete/" + studentid);
alert("Student deleted Successfully");
Load();
}
async function update(event)
{
event.preventDefault();
try
{
await axios.put("http://localhost:8081/api/v1/student/edit/" + studentid ,
{
studentname: studentname,
studentaddress: studentaddress,
mobile: mobile
});
alert("Registation Updateddddd");
setId("");
setName("");
setAddress("");
setMobile("");
Load();
}
catch(err)
{
alert("Student Updateddd Failed");
}
}
