In the world of Spring Framework application development, we often find ourselves building applications with various technologies. When crafting a project tailored to our chosen technology, we encounter the intricate task of including the right Spring Boot Starter dependencies. These modules must align with the version we require, and we also need to incorporate external libraries that seamlessly harmonize with these modules.
Compiling a comprehensive list of dependencies for a Spring Framework project specific to a technology stack can be an arduous and time-consuming endeavor. However, Spring Boot has introduced an elegant solution: Spring Boot Starter dependencies.

Understanding Spring Boot Starter Dependencies
Spring Boot Starter dependencies are essentially Maven projects, but with a unique twist. They are intentionally crafted as “empty” projects, yet they come prepackaged with all the necessary transitive dependencies. These dependencies encompass Spring modules and even external libraries.
Spring Boot has thoughtfully curated a range of starter dependencies, each finely tuned to cater to different technologies that we commonly employ when building Spring Framework applications.
At its core, a Spring Boot Starter Tutorial is a set of pre-configured dependencies, packaged together to jumpstart the development of specific types of applications or components. These starters contain everything you need to get up and running quickly, reducing the complexity of configuring your application manually.
Dependency Management in Spring Boot
Let’s break down the process:
- Select the Relevant Starter Dependency:
- Depending on the technology stack you intend to utilize for your application, you can pinpoint the appropriate Spring Boot Starter dependency.
- Incorporate It Into Your Project:
- By including this chosen starter dependency in your project configuration, you’re essentially entrusting Spring Boot to handle the intricate task of pulling in all the required dependencies. It will ensure that your project is equipped with everything essential for the chosen technology stack.
Examples:
Let’s explore a few examples of Spring Boot Starter dependencies:
- Spring Framework 3.x:
spring-boot-starter-1.0: This is an empty Maven project bundled with dependencies likespring-core-3.4.2,spring-beans-3.4.2, and more.
- Spring Framework 4.x:
spring-boot-starter-1.3: Another empty Maven project, but tailored for Spring Framework 4.x, including dependencies likespring-core-4.1,spring-beans-4.1, and more.
Putting It All Together: Simplifying Dependency Management
Imagine you’re embarking on a project, such as a Hospital Management System (HMS). Here’s how you can leverage Spring Boot Starter dependencies:
- Create a Maven Project:
- Start by initiating a new Maven project for your application, ensuring that it’s structured properly.
Example:
Suppose you want to create a Maven project for a web application named “MyWebApp.”
- Open a Terminal or Command Prompt: Navigate to the directory where you want to create your project.
- Use Maven’s Archetype Plugin: Execute the following command to create a new Maven project using the “maven-archetype-webapp” archetype, which is suitable for web applications:
mvn archetype:generate -DgroupId=com.example -DartifactId=MyWebApp -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false-DgroupId: Specifies the project’s group ID, typically in reverse domain format (e.g., com.example).-DartifactId: Sets the project’s artifact ID, which is the project’s name (e.g., MyWebApp).-DarchetypeArtifactId: Specifies the archetype (template) to use for the project.
3. Navigate to the Project Directory: Change your current directory to the newly created project folder:
cd MyWebApp4. Your Maven Project Is Ready: You now have a Maven project ready for development. You can start adding code and configuring your project as needed.
Example:
Suppose you want to add Spring Boot Starter dependencies for building a web application using Spring Boot.
- Open the
pom.xmlFile: In your Maven project, locate thepom.xmlfile. This file is used to manage project dependencies. - Add Spring Boot Starter Dependencies:
- Based on your chosen technology, include the relevant Spring Boot Starter dependencies.
- Ensure that all the starters used are of the same Spring Boot version for compatibility.
- Edit the
pom.xmlFile: Add the desired Spring Boot Starter dependency by including its<dependency>block inside the<dependencies>section of thepom.xmlfile. For a web application, you can add the “spring-boot-starter-web” dependency:
Spring boot starter dependency
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
<dependencies>
<!-- Other dependencies -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.7.15</version>
</dependency>
</dependencies><groupId>: Specifies the group ID for the dependency (in this case, “org.springframework.boot”).<artifactId>: Sets the artifact ID for the dependency (e.g., “spring-boot-starter-web”).
3. Save the pom.xml File: After adding the dependency, save the pom.xml file. Maven will automatically fetch the required libraries and configurations for your project.
4. Build Your Project: To apply the changes, build your project using the following command:
mvn clean installMaven will download the necessary “Spring Boot Starter” dependencies and make them available for your project.
With these steps, you’ve successfully created a Maven project and added “Spring Boot Starter” Dependencies, making it ready for Spring Boot application development
Below is a screenshot illustrating the generated project, ‘MyWebApp,’ along with the added starter dependencies.
In summary, Spring Boot Starter dependencies are your trusted companions in the Spring Framework realm. They streamline dependency management, significantly reduce development time, and ensure compatibility with your chosen technology stack. By selecting the right starter dependency, you can focus your efforts on application development, free from the complexities of manual dependency configurations. Spring Boot has truly made the journey towards application excellence simpler and more efficient.
