Cover image for Building a Task Management Application using Rest API, Spring Boot, Maven and Fauna

Posted on Nov 30, 2021 • Updated on Jul 23, 2022

Building a Task Management Application using Rest API, Spring Boot, Maven and Fauna

Written in connection with the Write with Fauna Program .

This article focuses on the tutorial steps in building a Rest API using the Java Programming framework (Spring Boot), Maven, and Fauna. We used Fauna as our database to save our information and integrated this into our Spring Boot project. We also outlined these steps to make it easy for beginners to follow through and implement the same using these steps when working on a similar project. The Rest API is more suitable for server-side API rendering. Hence, the REST API is a valuable architectural style for microservices because of its simplicity, scalability and flexibility. In microservice architecture, each application is designed as an independent service from the other. We recall that microservices rely on small teams to deploy and scale their respective services independently, this makes the REST API an invaluable resource to this architectural style.


To fully understand this part of the tutorial, you are required to have the following:

What is an API?

In the simplest form, an API is the acronym for application programming interface that allows for two or more different applications to talk to each other. Everytime you make use of these applications, the applications on your phone, gadgets or computer connect to the internet and send data to the server. This data retrieved by the server is then interpreted, and some actions are performed and a feedback is sent back to you in a human or readable format. The API also provides a level of security here since each communication entails a small packet of data, the data sharing here only entails that which is necessary. Another additional benefit of RESTful APIs is its Client-Server constraints. This constraint operates on the concept that the client and server side should be separated from each other. This is referred to as separation of concerns which guarantees more efficiency in our application. Therefore, I should be able to make changes on my client side without affecting my database design on the server and vice-versa. This makes our application to be loosely coupled and easily scalable . This article teaches how to create a SpringBoot and Restful API that performs CRUD (Create, Read, Update and Delete) operations by making a database call to a Fauna. The application we will be building in this tutorial is a “task-management app” for users to manage all their daily tasks.

Key Takeaways

Project Setup

To initialize the project we are going to use spring initializer . Enter the maven project properties of the project including the dependencies as shown below and click on the generate button. This will generate a zip file and download it for you. Unzip it and open it in your favorite IDEA and sync the dependencies with Maven.

spring initializer image

For this project we are going to add two dependencies namely:

The EntryPoint of the Application

The beauty of SpringBoot lies in how easy it is to create stand-alone, production-grade spring-based applications that you can "just run". If you open your file.

SpringBoot applications should have an entry point class with the public static void main(String[] args) methods, which is annotated with the @SpringBootApplication annotation and will be used to bootstrap the application. It is the main method which is the entry point of the JVM to run our application. The @SpringBootApplication annotation informs the Spring framework, when launched, to scan for Spring components inside this package and register them. It also tells Spring Boot to enable Autoconfiguration, a process where beans are automatically created based on classpath settings, property settings, and other factors. The @SpringBootApplication annotation has composed functionality from three annotations namely @EnableAutoConfiguration , @ComponentScan , and @Configuration . So we can say it is the shortcut for the three annotations.

Now, we can now run our application. We can do this by either clicking on the play button on our IDEA or running this command: mvn spring-boot:run on our command line. Navigate to the root of the project via the command line and execute the command. Boom! Tomcat started on port 8081 which is the port we configured our application to run.

Maven as a dependency management tool.

The pom.xml file houses the dependencies, Maven plugins in our project. The dependency section simply contains the dependencies we added to our project namely SpringWeb and springfox for documenting our api.

Adding Additional Maven Dependencies

In this section we are going to add additional deficiencies to the project. To do this, we navigate to Maven Repository and search for the Fauna dependency and add it to the dependencies section of the pom.xml file:

Next, we can now proceed to create a database on the Fauna dashboard, and generate a server key and configure FaunaClient in the Spring Boot project. To create a database and server key for our SpringBoot project, we are going to register a Fauna account. To do this, click on this link sign up today and ignore if you have one already. After signup, you get a prompt to create a database like the image below:

image shows Fauna sign-up page

Creating a Fauna API Key

To create a Fauna API Key, you would go to your settings on the Fauna sidebar (at the top left of the screen). This Fauna API key is required to connect the database to our Task_Management_App.

image showing Fauna API keys generation

Configuring Fauna Client

In the resources folder within the src/main folder, open file and add the secret key that you have generated. fauna-db.secret=”your api secret key should be here” Next we need to create a bean creates a single instance of the configuration with the help of the @Scope annotation and inject our api key using the @value annotation.

Project Structure

Our project will be structured into four subpackages: Data: This subpackage will house our Data access layer, which will include our Domain and repository.

Creating The Domain Class

In the data package, create another package called models. Inside the models package, create a class called Task with the following code:

Inside the data package, create a package with the name payloads. This package will have two sub-packages “request” and “response” to handle our request payloads and response payloads respectively.

Request payloads

Inside the request package create an EmployeeRequest class with the following code:

@NotBlank and @notnull : These two annotation checks and validate the fields where they are mapped to ensure the values are not blank and null respectively.

Response payload

Inside the response package create a TaskResponse class with the following code:

The Repository

Inside the data package, create a sub-package called a repository. Then create an interface called “TaskRepository” that extends JpaRepository. The JpaRepository is generic so it takes a model class(Type) and the data type of the primary key. Write the following code in the TaskRepository interface.

Next let’s create a class called FaunaRepository that will contain methods that will allow us to perform the CRUD Operation. We are going to first create an interface that will contain these methods. Let's call the interface Repository .

The above class provides an implementation to the methods defined on the interface. You can look up the Fauna documentation for Java by clicking on this link: Fauna/JVM doc

The TaskService

Create a service package under the taskmanager directory. This package is going to house the business logic. We have divided the service into two, an interface where the methods of our business logic will be declared and a concrete class that implements the interface. Create an interface with the name “taskService" with the following code:

Next, create a TaskServiceImpl class that implements the TaskService interface. Write the following code:

@Service annotation is a specialized form of @Component . With the @Service annotation, the class that is annotated is registered in the application context and accessible during classpath scanning.

The TaskServiceImpl class implemented the TaskService interface by overriding the method and implementing them. The class throws an exception(ResourceNotFoundException- This is the custom exception class we created that extends RunTimeException) where the Id supplied to get a single task does not exist on the database.

The Controller

Create a package called web under the taskmanager package . This package is going to house the APIs controller. Create an TaskController class with the following code:

Documenting your API with Swagger

We already added the io.springfox dependency to the pom.xml. With this dependency we will document the API so that it will be easy for other developers to use it. All is required is to add the following line of code at the class level of our controller as follows:

We added the @ApiResponse annotation from swagger at the class level. As simple as this, our APIs are fully documented. Go to localhost:8081/swagger-ui to access the documentation and test that our APIs are still working properly. Use the Swagger API document at localhost:8900/swagger-ui to add an employee, get, update and delete an employee.


In this article project, we successfully built a Task Management Application using SpringBoot framework and Maven as our dependency management and build tools. We used Fauna as our Cloud datastore. Additionally, we learned how to throw exceptions in our application which ensures that our application is fault-tolerant and resilient. We also learned how to document our API using Swagger .

Task manager with Java

Hi so I'm a student in high school and have a project to do with CS. I'm trying to write a program that shuts down an external application after a certain amount of time has passed. That time part was pretty easy to do but now the problem is the actual shutting down of the problem. I looked around and couldn't find anything that worked for me and need some help with this.

Here's what I have so far:


Still needs some working on when it comes to Mac OS. But the windows part works great. Added some video games that i had on my computer to shut down.

Kevin's user avatar

Use System.getProperty(""); to determine which OS is running the program:

Then kill the task based on the OS:

---- For Windows ---

You could use the method Runtime.getRuntime().exec(); to execute a cmd command in order to kill the process.

Replacing process.exe with the filename of the process you want to kill. You might have to run the program as administrator, because taskkill requires elevation to kill some processes.

--- For Mac ---

For mac, you will use the same method, just passing different arguments to it. Consider the following:
