Springboot +Mysql+ Angular example

Here is an example of a simple web application using Spring Boot, MySQL, and Angular.

Backend (Spring Boot + MySQL)

1. Create a new Spring Boot project using your favorite IDE.

2. Add the following dependencies to your pom.xml file:


    <!-- Spring Boot dependencies -->





    <!-- MySQL Connector/J -->






    <!-- Spring Data JPA -->






3. Create a MySQL database and update the application.properties file to configure the database connection.






4. Create a JPA entity class for your database table. Here's an example:


@Table(name = "users")

public class User {


    @GeneratedValue(strategy = GenerationType.IDENTITY)

    private Long id;

    @Column(nullable = false)

    private String firstName;

    @Column(nullable = false)

    private String lastName;

    // getters and setters


5. Create a Spring Data JPA repository interface to define database operations. Here's an example:


public interface UserRepository extends JpaRepository<User, Long> {


6. Create a Spring MVC controller to handle REST API requests. Here's an example:



public class UserController {


    private UserRepository userRepository;


    public List<User> getUsers() {

        return userRepository.findAll();



    public User createUser(@RequestBody User user) {

        return userRepository.save(user);



    public User updateUser(@PathVariable Long id, @RequestBody User user) {


        return userRepository.save(user);



    public void deleteUser(@PathVariable Long id) {




Frontend (Angular)

1. Install the latest version of Node.js and Angular CLI.

2. Create a new Angular project using the CLI:

ng new my-app

3. Change to the project directory and install the rxjs and @angular/common/http dependencies:

  cd my-app

npm install rxjs @angular/common/http

4. Create a new Angular component for displaying and managing user data. Here's an example:

  ng generate component user

5. Update the user.component.ts file to define the user model and API service:

 import { Component, OnInit } from '@angular/core';

import { HttpClient } from '@angular/common/http';

import { Observable } from 'rxjs';

interface User {

  id: number;

  firstName: string;

  lastName: string;



  providedIn: 'root'


export class UserService {

  private apiUrl = '/api/users';

  constructor(private http: HttpClient) {}

  getUsers(): Observable<User[]> {

    return this.http.get<User[]>(this.apiUrl);


  createUser(user: User): Observable<User> {

    return this.http.post<User>(this.apiUrl, user);
