Create spring boot project

There are many different ways to create a spring boot application, you can follow the below articles to create one –

>> Create spring boot application using Spring initializer
>> Create spring boot application in Spring tool suite [STS]
>> Create spring boot application in IntelliJ IDEA

Add maven dependencies

Open pom.xml and add the following dependencies –

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
		<relativePath/> <!-- lookup parent from repository -->
	<description>Spring boot rest api</description>




spring-boot-starter-web dependency for building web applications using Spring MVC. It uses the tomcat as the default embedded container. spring-boot-devtools dependency for automatic reloads or live reload of applications. spring-boot-starter-data-jpa dependency for performing database operations.

lombok dependency is a java library that will reduce the boilerplate code that we usually write inside every entity class like setters, getters, and toString(). mysql-connector-java dependency is to store the data into the database.

Create Database

Open MySQL workbench and execute the following statements-

CREATE DATABASE employeeportal;

USE employeeportal;

CREATE TABLE tbl_employees
    name VARCHAR(255) NOT NULL,
    location VARCHAR(255) NOT NULL,
    department VARCHAR(255) NOT NULL

INSERT INTO tbl_employees(name, location, department) 
VALUES("Bushan", "India", "IT");

INSERT INTO tbl_employees(name, location, department) 
VALUES("Bharath", "Australia", "Marketing");

Configure Datasource

Open application.properties file and add the following content



Create an Entity class

Create Employee.java class inside in.bushansirgur.springbootrestapi.entity package and add the following content

package in.bushansirgur.springbootrestapi.entity;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Table(name = "tbl_employees")
public class Employee {
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	private Long id;
	private String name;
	private String location;
	private String department;
  • All your domain models must be annotated with @Entity annotation. It is used to mark the class as a persistent Java class.
  • @Table annotation is used to provide the details of the table that this entity will be mapped to.
  • @Id annotation is used to define the primary key.
  • @GeneratedValue annotation is used to define the primary key generation strategy.
  • @Column annotation is used to define the properties of the column that will be mapped to the annotated field.

Create a Repository

Create EmployeeRepository.java interface inside in.bushansirgur.springbootrestapi.repository package and add the following content

package in.bushansirgur.springbootrestapi.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import in.bushansirgur.springbootrestapi.entity.Employee;

public interface EmployeeRepository extends JpaRepository<Employee, Long>{


Create a Controller

Create EmployeeController.java class inside in.bushansirgur.springbootrestapi.controller package and add the following content

package in.bushansirgur.springbootrestapi.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import in.bushansirgur.springbootrestapi.entity.Employee;
import in.bushansirgur.springbootrestapi.repository.EmployeeRepository;

public class EmployeeController {
	private EmployeeRepository eRepo;
	public List<Employee> getAllEmployees() {
		return eRepo.findAll();
	public Employee getEmployeeById(@PathVariable Long id) {
		return eRepo.findById(id).get();
	public Employee saveEmployeeDetails(@RequestBody Employee employee) {
		return eRepo.save(employee);
	public Employee updateEmployee(@RequestBody Employee employee) {
		return eRepo.save(employee);

We are calling repository method save() to update the data to the database.

Run the App

Run the application using the below maven command –

mvn spring-boot:run

Open the postman rest client and test the APIs




Create React Project

In order create react project, first we should install Node.js. Download the Node.js from the below link and install on your system


Once Node.js is installed on your system, you can verify it by executing the below command

node -v

To create new react project, we can use create-react-app library. Open the command prompt, enter the following command

npx create-react-app my-app

This will create react starter project. Next open the project in any text editor

Install axios library

On the root of the project, enter the following command to install axios library

npm install axios
  • Axios is a simple promise based HTTP client for the browser and node.js.
  • Axios provides a simple to use library in a small package with a very extensible interface.

Install React Router DOM library

On the root of the project, enter the following command to install react-router-dom library

npm install react-router-dom

Intall Bootstrap library

On the root of the project, enter the following command to install bootstrap library

npm install [email protected]

Configure axios library

Inside src folder, create http-common.js file and add the following content –

import axios from "axios";

export default axios.create({
    baseURL: 'http://localhost:8080/api/v1',
    headers: {
        'Content-Type': 'application/json'

Create Employee Service

Inside src/services folder, create employee.service.js file and add the following content –

import httpClient from "../http-common";

const getAll = () => {
    return httpClient.get('/employees');

const create = data => {
    return httpClient.post("/employees", data);

const get = id => {
    return httpClient.get(`/employees/${id}`);

const update = data => {
    return httpClient.put('/employees', data);
export default { getAll, create, get, update };

Create EmployeeList Component

Create EmployeesList.js inside src/components folder and add the following content

import { useEffect, useState } from 'react';
import { Link } from 'react-router-dom';
import employeeService from '../services/employee.service';

const EmployeeList = () => {

  const [employees, setEmployees] = useState([]);

  useEffect(() => {
      .then(response => {
        console.log('Printing employees data', response.data);
      .catch(error => {
        console.log('Something went wrong', error);
  }, []);

  return (
    <div className="container">
      <h3>List of Employees</h3>
        <Link to="/add" className="btn btn-primary mb-2">Add Employee</Link>
        <table className="table table-bordered table-striped">
          <thead className="thead-dark">
            employees.map(employee => (
              <tr key={employee.id}>
                  <Link className="btn btn-info" to={`/employees/edit/${employee.id}`}>Update</Link>

export default EmployeeList;

Create Add Employee Component

Create AddEmployee.js inside src/components folder and add the following content

import { useState } from "react";
import { Link, useHistory, useParams } from "react-router-dom";
import { useEffect } from "react/cjs/react.development";
import employeeService from "../services/employee.service";

const AddEmployee = () => {
    const[name, setName] = useState('');
    const[location, setLocation] = useState('');
    const[department, setDepartment] = useState('');
    const history = useHistory();
    const {id} = useParams();

    const saveEmployee = (e) => {
        const employee = {name, location, department, id};
        if (id) {
                .then(response => {
                    console.log('Employee data updated successfully', response.data);
                .catch(error => {
                    console.log('Something went wrong', error);
        } else {
            .then(response => {
                console.log("employee added successfully", response.data);
            .catch(error => {
                console.log('something went wroing', error);

    useEffect(() => {
        if (id) {
                .then(employee => {
                .catch(error => {
                    console.log('Something went wrong', error);
    }, [])
        <div className="container">
            <h3>Add Employee</h3>
                <div className="form-group">
                        className="form-control col-4"
                        onChange={(e) => setName(e.target.value)}
                        placeholder="Enter name"

                <div className="form-group">
                        className="form-control col-4"
                        onChange={(e) => setDepartment(e.target.value)}
                        placeholder="Enter Department"

                <div className="form-group">
                        className="form-control col-4"
                        onChange={(e) => setLocation(e.target.value)}
                        placeholder="Enter Location"
                <div >
                    <button onClick={(e) => saveEmployee(e)} className="btn btn-primary">Save</button>
            <Link to="/">Back to List</Link>

export default AddEmployee;

Create NotFound Component

Create NotFound.js inside src/components folder and add the following content

const NotFound = () => {
    return (
            <p>The page you are looking is not yet developed.</p>
export default NotFound;

Configure React Router

Open App.js and add the following content

import { BrowserRouter, Switch, Route } from 'react-router-dom';
import EmployeeList from './components/EmployeesList';
import NotFound from './components/NotFound';
import 'bootstrap/dist/css/bootstrap.min.css';
import AddEmployee from './components/AddEmployee';

function App() {
  return (
            <Route exact path="/" component={EmployeeList} />
            <Route path="/add" component={AddEmployee} />
            <Route path="/employees/edit/:id" component={AddEmployee} />
            <Route path="*" component={NotFound} />

export default App;

At the top, we are importing the bootstrap.min.css library

Run the React App

On the root of the project, open the command prompt, execute the following command

npm start

This will run the application on the port, localhost:3000
