Architecture
Spring Boot is a framework that The Model-View-Controller (MVC) architecture is a fundamental design pattern used in software development, and Spring Boot embraces this architectural paradigm to create robust and maintainable web applications. At its core, MVC divides an application into three interconnected components: the Model, the View, and the Controller. Each component has a distinct role within the application, contributing to its overall structure and functionality.
- Model: The Model component corresponds to all the data-related logic that the user works with. This can represent either the data that is being transferred between the View and Controller components or any other business logic-related data. It can add or retrieve data from the database. It responds to the controller’s request because the controller can’t interact with the database by itself. The model interacts with the database and gives the required data back to the controller¹. Spring Boot simplifies the creation of the Model by providing tools for data persistence, such as databases or APIs, making it easier to manage and access data. This Code below is the Model example for User Data
package com.riskee.globalchat.model.dto;
import jakarta.persistence.*;
@Entity
@Table(name = User.TABLE_NAME)
public class User {
public static final String TABLE_NAME = "users";
public static final String USERNAME = "username";
public static final String EMAIL = "email";
public static final String PASSWORD = "password";
public static final String AVATAR_ID = "avatar_id";
public static final String LEVEL = "level";
public static final String EXP = "exp";
public static final String COINS = "coins";
public static final String AVATARS = "avatars";
public static final String ITEMS = "items";
@Id
@Column(name = USERNAME)
private String username;
@Column(name = EMAIL)
private String email;
@Column(name = PASSWORD)
private String password;
@Column(name = AVATAR_ID)
private int avatarId = 2;
@Column(name = LEVEL)
private int level = 1;
@Column(name = EXP)
private int exp = 0;
@Column(name = COINS)
private int coins = 0;
@Column(name = AVATARS)
private String avatars = "";
@Column(name = ITEMS)
private String items = "";
public User() {
this.username = "null";
this.email = "null";
this.password = "null";
}
// Getters and setters (omitted for brevity)
}- View: The View component is used for all the UI logic of the application. It generates a user interface for the user. Views are created by the data which is collected by the model component but these data aren’t taken directly but through the controller. It only interacts with the controller¹. The View component in Spring Boot handles the presentation and user interface of the application. It is responsible for rendering data from the Model into a format that users can interact with, such as HTML for web applications. Spring Boot integrates seamlessly with various view technologies like Thymeleaf, FreeMarker, or JSP, allowing developers to choose the one that best suits their needs. This code below is the view example for a simple Home Page.
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Our Homepage</title>
</head>
<body>
<header>
<h1>Welcome to Our Homepage</h1>

<h2>About Me</h2>
<p>This is a simple homepage created by us</p>
</section>
</main>
<footer>

</body>
</html>- Controller: The controller is the component that enables the interconnection between the views and the model so it acts as an intermediary. The controller doesn’t have to worry about handling data logic, it just tells the model what to do. It processes all the business logic and incoming requests, manipulates data using the Model component, and interact with the View to render the final output¹. Controllers are the entry points for incoming requests in a Spring Boot application, and they play a pivotal role in defining the application’s behavior. This code below is the Controller example for Home Page.
package com.riskee.globalchat.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class HomeController {
@GetMapping("/")
public String home() {
return "home"; // This corresponds to the "home.html" template in resources/static
}
}The MVC architecture in Spring Boot offers several advantages. It promotes a clear separation of concerns, making the codebase more modular and maintainable. Developers can work on different components independently, enhancing code reusability and collaboration. Additionally, Spring Boot provides built-in features like request mapping, data binding, and form handling, simplifying the development process and reducing boilerplate code.
Moreover, MVC aligns with the principles of RESTful web services, enabling the creation of scalable and resource-oriented applications. It also supports the development of diverse types of applications, from traditional web apps to RESTful APIs and single-page applications (SPAs). Overall, Spring Boot’s implementation of the MVC architecture empowers developers to create web applications that are both flexible and robust, capable of adapting to evolving requirements and delivering a superior user experience.
Spring Boot Vs Others
On other hands, we want to find a similar Spring Boot framework with other frameworks, such as Node.js and Laravel.

Meanwhile, the Controller acts as an intermediary, receiving user requests and coordinating the communication between the Model and View, resulting in a modular and maintainable codebase for building robust web applications.
Node.js: The main element in single-threaded Node.js architecture is the event loop. The event loop is the mechanism that takes callbacks (functions) and registers them to be executed at some point in the future. It operates in the same thread as the proper JavaScript code. When a JavaScript operation blocks the thread, the event loop is blocked as well. The worker pool is an execution model that spawns and handles separate threads, which then synchronously perform the task and return the result to the event loop. The event loop then executes the provided callback with said result. (LogRocket)
Laravel: Laravel, a PHP-based framework, adheres to the well-known Model-View-Controller (MVC) architectural pattern, which is the same with Spring Boot that elegantly divides an application into distinct components, ensuring a clear separation of business logic, presentation, and data handling.
