How To Develop a Fast and Modern Java Application by Using Spring Boot?

Let’s look at how to create a quick and cutting-edge Java application with Spring Boot now that we’ve established why it’s a great option for creating Java apps. We’ll cover in this section the following topics:

  • Setting up a development environment
  • Understanding the Spring Boot architecture
  • Creating a simple Spring Boot application
  • Implementing data persistence
  • Securing your application
  • Test your application
  • Ready to deploy your application

You first need to set up your development environment before you begin developing a Java application. This entails setting up the Spring Boot CLI, a Java Integrated Development Environment (IDE), and the Java Development Kit (JDK).

Setting Up a Development Environment

So the development process starts with setting up a development environment before you can begin programming using Spring Boot. The following steps are:

  1. Install Java Development Kit (JDK): Installing JDK is a first step because Spring Boot requires JDK 8 or a later version. JDK is available for download and installation on the official Oracle website.
  1. Install an Integrated Development Environment (IDE): you can use any IDE such as IntelliJ IDEA, Eclipse, or NetBeans. However, IntelliJ IDEA is one of the most often used IDEs for Spring Boot development.
  1. Install Maven: Maven is an automated tool for developing and deploying applications. It is used to manage dependencies. It can be installed and downloaded from the Apache Maven website.
  1. Install Spring Boot: You can add Spring Boot as a dependency to your Maven project or download and install Spring Boot from the official Spring Boot website directly.

This is the complete development environment setup process. Now let’s move on to the next section.

Understanding the Spring Boot Architecture

The Spring Platform, a well-liked Java framework for creating online applications, is the foundation upon which Spring Boot is constructed. Application-grade applications are simple to create because of the pre-configured functionality offered by Spring Boot. The basic parts of a Spring Boot setup are mentioned below:

  1. Spring Boot Starter: To help you quickly get started with Spring Boot development, Spring Boot Starter is a collection of pre-configured dependencies. The starting that best meets your needs, such as Web, Data, Security, or Messaging, is yours.
  1. Spring Boot Autoconfiguration: Based on classpath dependencies, Spring Boot autoconfiguration automatically configures the Spring application. By supplying your settings, you can alter the default ones.
  1. Spring Boot Actuator: Spring Boot Actuator is an extensive collection of tools that offers ready-for-production features, like health checks, metrics, and monitoring. The actuator can be used to troubleshoot issues that could occur and monitor how well your application is performing.

Creating a Simple Spring Boot Application

Creating a Spring Boot application is our next step, so let’s create a simple Spring Boot application to understand the basic structure and components.

  1. Create a new Maven project in your already installed IDE.
  1. Add the Spring Boot starter dependency in the pom.xml file.
  1. Create a Spring Boot main class with the help of @SpringBootApplication annotation.
  1. Add a REST endpoint with the @RestController and @RequestMapping annotations.
  1. Run the application and test the REST endpoint with a web browser or a REST client.

Implementing Data Persistence

To store and recover data in your Spring Boot application, you can use many data persistence technologies, such as relational databases, NoSQL databases, or file systems. Here are the several steps to implement data persistence in your application:

  1. Choose a data persistence technology and add the corresponding dependency to your Spring Boot project.
  1. Define the data model with JPA annotations or use a data mappings framework, such as MyBatis or Hibernate.
  1. Create a repository interface that extends the Spring Data interface, such as CrudRepository or PagingAndSortingRepository.
  1. Use the repository in your service layer to conduct CRUD operations on the database.

Securing Your Application

Spring security is a robust and flexible security framework that provides authentication, authorization, and access control for your Spring Boot application.

Here are the following steps to integrate security in your Spring Boot application with Spring Security:

  1. Add the Spring Security starter dependency to your Spring project.
  1. Then define a security configuration class that extends WebSecurityConfigurationAdapter and overrides the configure() method.
  1. Configure the authentication mechanism, such as in-memory authentication, database authentication, or LDAP authentication.
  1. Configure the authorization mechanism, such as role-based or permission-based access control.

Test the Application

After developing your Spring Boot Java application, the next step is to test the application and ready it for final deployment. This development process will give you a final result on how your app has performed or whether it is ready for deployment. So to test your application, you can use various testing frameworks, such as JUnit or Mockito. You can choose either of them; they are all pretty good for testing application performance and operations. These frameworks will allow you to write tests for your applications to ensure that it works as you expected.

Once you have tested your application, it's time to deploy it. You can deploy your Spring Boot Java application to a production environment. Spring Boot supports various deployment options, such as deploying the application to a server or running it as a standalone application on the Java platforms.

Deploying Your Application

The final stage is here after crossing so many stages earlier. To deploy your final product (Spring Boot application), you must use various deployment options, such as standalone executables, traditional WAR files, or containerized Docker images.

Here are the final steps to deploy your Java application:

  1. Build a standalone executable JAR file through Maven builds command "mvn clean package," You can also use your IDE's build tools, which will be a good choice to complete this process quickly.
  1. Run the JAR file using the command "java -jar ."
  1. If you want to deploy your Java application to a web server, such as Tomcat or Jetty, you can package your application as a WAR file and deploy it to the server.
  1. Alternatively, you can use Docker to containerize your Java application and deploy it to a cloud-based service such as AWS or Azure; both are top-notch cloud service providers.

Best Practices for Developing Fast and Modern Java Applications Using Spring Boot

It's critical to adhere to certain best practices when creating a quick and contemporary Java application with Spring Boot. These procedures guarantee your application's sound design, scalability, and maintainability.

Among these ideal practices are the following:
