Top 7 Exciting Spring Boot Projects & Topics For Beginners [2020]

The best way to learn any technology is by using it. So, if you want to strengthen your knowledge of Spring Boot, you should work on a few Spring Boot projects. A significant issue with projects is it’s quite challenging to come up with their ideas. 

To help you there, we’ve compiled a list of Spring Boot project ideas. You can pick any one of the ideas we’ve shared here so you can test your knowledge. 

But we before discussing the projects, let’s look at the basics of Spring Boot:

What is the Spring Boot?

Spring Boot is an open-source framework based on Java, which allows users to create micro Services. A microservice enables developers to develop and deliver services independently. Here, every service has its process, which enhances the lightweight model. Spring allows you to develop a production-grade stand-alone application you can run. You can start your process without performing the stressful configuration setup of Spring.

That’s why it’s widely popular among Java developers. Developing and understanding spring applications is relatively easy. Moreover, as it gets rid of the complex configuration process, you develop and deploy applications faster with higher efficiency and productivity.

Let’s now focus on different Spring Boot project ideas:

Spring Boot Project Ideas

1. Use Spring Boot to build a Web Application

This is a beginner-level project. You can start your Spring learning journey by creating a simple web application. You’ll use either Maven 3.2+ or Gradle 4+. You’ll first have to create an application class then run the application. You’ll also have to add unit tests. For starters, you can build a website for a business. Apart from application class and unit tests, your web application will require services too. To add services, you’ll have to use the actuator module of Spring Boot. 

Here’s the sample code for creating the application class:

package com.example.springboot;

import java.util.Arrays;

import org.springframework.boot.CommandLineRunner;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.context.ApplicationContext;

import org.springframework.context.annotation.Bean;

@SpringBootApplication

public class Application {

 public static void main(String[] args) {

  SpringApplication.run(Application.class, args);

 }

 @Bean

 public CommandLineRunner commandLineRunner(ApplicationContext ctx) {

  return args -> {

   System.out.println(“Let’s inspect the beans provided by Spring Boot:”);

   String[] beanNames = ctx.getBeanDefinitionNames();

   Arrays.sort(beanNames);

   for (String beanName : beanNames) {

    System.out.println(beanName);

   }

  };

 }

}

After you’ve created a web application with Spring Boot, you’ll be familiar with the basics of this powerful tool. You can take this a step further by adding more features to your web app and enhance its functionality. 

2. Create REST Service for an Education Site

In this project, you’ll create a REST service for a course-providing website. REST is an abbreviation for REpresentational State Transfer, and to create these services; you’ll use Spring Boot. For example, one service can ask for the courses a particular student signed up for, through the Get request method. Other service examples include asking for the students of a specific class, as well as a request to register a student. 

To complete this project, you’ll need Maven 3.0+, an IDE, and JDK 1.8+. You should also be familiar with the Richardson Maturity Model as you’ll need that to identify the level of maturity of your Restful Web Service. This project will help you get more familiar with REST and its implementation through Spring Boot.

REST gives architectural constraints to services, which are called RESTful services. These constraints comprise of Cacheable results (such as HTTP cache), uniform URL, presence of a service consumer and producer, and statelessness. 

You can use the Spring Web MVC as your web framework. To bootstrap this project (as well as other Spring Boot projects), you can use Spring Initializr. You’d have to choose the Group, the Artifact, and Web, Actuator, and DevTools as your dependencies there. Your service will require data too. For that purpose, you can use an in-memory store such as “ArrayList”.

You’ll also get accustomed to using various request methods while completing this project because you’ll have to use GET, PUT, POST, and DELETE.

3. Create an Employee Management System (Using Spring Boot and Thymeleaf)

By using Spring Boot and Thymeleaf, you can build an employee management system for an organization. But for this, you should be familiar with the basic concepts of both of these technologies. The user of your EMS solution should be able to add an employee, view all employees, delete any employee, sort the data, and paginate. 

It is a rather complex project that might take you some time to complete. However, once you’re done, you’d be familiar with the Thymeleaf CRUD, Spring Boot, and their various functionalities in handling databases. 

You’ll have to use an IDE, Spring Data JPA, Spring Boot 2.2, Maven 3.2+, and Spring Framework 5.2. You should divide it into steps and complete them one-by-one. Start with setting up the database, and then start adding the required features. 

4. Work on the Open-source Project Sagan

Project Sagan is a real-world app that facilitates the official website of Spring Boot (spring.io). It’s available on Github and is a popular open-source project. By working on this project, you’ll get to learn a lot about the capabilities of Spring Boot while also getting familiar with its framework, Elasticsearch, Thymeleaf UI, and Gradle.

As it powers a real website, you can see its results anytime. You can see the progress of other developers and how they’ve worked on this project as well. 

It’s a great way to experience the various functionalities of Spring Boot. 

5. Create a Web App with Spring Boot Starter Web

Spring Boot starters can help you get rid of many complicated steps present in the development process. They are dependency descriptors you can add in your application and get all the benefits of Spring. Spring Boot Starter Web is a popular starter. It allows you to build an app with restful services. 

In this project, you’ll first have to use the Spring Initializr to bootstrap the project. Then, you’ll add Spring Boot Starter Web. It performs auto-configuration and adds the necessary dependencies you’d need for any web application.

This means your project gets dependencies for Tomcat, Validation API, beans, MVC, and many others. As you can see, by using Spring Boot Starter Web, you can easily make the development process more productive. 

This was just an example, and you can use many other Spring Boot starters and enhance your results.

6. Use LDAP to Authenticate a User

User authentication is a popular requirement of nearly every website and application. Without a valid user authentication measure, a platform would risk compromising the data of that respective user. That’s why we have multiple authentication solutions available. In this project, you’ll work on an LDAP-based authentication system. To create this system, we’ll use Spring Security.

You should be familiar with Spring Security, Maven (or Gradle), and the fundamentals of LDAP before you begin working on this project.  

LDAP authentication refers to validating the combination of the password and username with a directory server (such as OpenDJ, MS Active Directory). It is quite common as it follows the client/server model. Working on this project will make you more familiar with LDAP and help you implement it in other places. You’ll get familiar with the concept of cybersecurity by working on this project as well. 

Like all other Spring projects, you should first begin by going to Spring Initializr and bootstrap your project. You can use Maven or Gradle to work on this project. You’ll then have to create an unsecured web application and set up Spring Security, after which you’ll have to use LDIF (LDAP Data Interchange Format) files to transfer user data.

7. Create a Contact Us Page (Handle Form Submission)

You can create a contact us page for any company that has a form. Handling form submission is a great skill, and completing a project in this field will enable you to solve many problems related to the same. 

You’ll first have to use Spring Initializr, then build a web controller (they handle HTTP requests), and once you’ve done that, make your application executable. Test the results once you’ve created the form. This is one of the beginner-level Spring Boot project ideas, but it’ll make you familiar with a vital concept of back-end development. 

If the project seems too simple, you can take it a step further and add the functionality of validating form inputs. Input validation is necessary for sensitive fields such as Login windows.
