What is Spring Boot?
The Spring Framework is an open-source application framework for the Java platform. Introduced in 2003, it provides a comprehensive programming and configuration model for modern Java-based enterprise applications.
Key Features of Spring Framework:
- Dependency Injection (DI): Manages objects and their dependencies, making the application easier to manage.
- Aspect-Oriented Programming (AOP): Enables separating cross-cutting concerns like logging, security, and transactions.
- Spring MVC: Provides tools to develop web applications using the Model-View-Controller architecture.
- Data Access Layer: Simplifies interaction with databases using JDBC, Hibernate, and JPA.
- Transaction Management: Supports both declarative and programmatic transaction management.
Spring allows developers to create loosely coupled, testable, and maintainable applications. However, it requires extensive configuration, which can be time-consuming for developers.
According to Statista, the following is a list and percentage of most used web frameworks among developers worldwide, as of 2024:
What is Spring Boot?
Spring Boot, introduced in 2014, is an extension of the Spring Framework. It simplifies the process of creating Spring-based applications by reducing the need for boilerplate code and configuration.
Key Features of Spring Boot:
- Embedded Servers: Comes with Tomcat, Jetty, or Undertow, eliminating the need for manual server deployment.
- Starter Dependencies: Provides ready-made dependencies to speed up development.
- Spring Boot CLI: Allows developers to write Groovy scripts to simplify application setup.
- Production-Ready Features: Offers metrics, health checks, and application monitoring out-of-the-box.
Spring Boot focuses on rapid development and minimizes the complexities of setting up and configuring a Spring-based project.
Spring Framework vs Spring Boot: A Detailed Comparison
Let’s analyze the Spring and Spring Boot difference across key areas:
Spring boot vs Spring framework
Aspect | Spring Framework | Spring Boot |
|---|---|---|
Setup | Requires manual configuration for components. | Auto-configures components, reducing setup time. |
Complexity | Higher complexity due to boilerplate code. | Simplified project setup with minimal code. |
Dependency Management | Dependencies must be added manually. | Starter dependencies manage everything automatically. |
Server Deployment | Requires external servers like Tomcat or Jetty. | Comes with embedded servers. |
Development Speed | Slower due to manual configuration and setup. | Faster development with ready-to-use components. |
Learning Curve | Steeper learning curve for new developers. | Easier to learn due to streamlined processes. |
Focus | Provides flexibility for enterprise-level applications. | Focuses on microservices and quick development. |
Why Spring Boot Over Spring?
If you’re wondering why Spring Boot over Spring, the answer lies in its simplicity and speed. Spring Boot eliminates the need for extensive configuration, allowing developers to focus on application logic.
- Quick Setup: Developers can get an application up and running within minutes.
- Production-Ready Features: Monitoring, metrics, and health checks come pre-configured.
- Simplified Microservices Development: Ideal for building scalable, independent Microservices.
Spring Boot retains the power of the Spring Framework while reducing its complexity, making it a go-to choice for modern development.
Is Spring and Spring Boot Same?
No, Spring and Spring Boot are not the same. While Spring is a comprehensive framework, Spring Boot is a tool built on top of Spring that simplifies application development.
- Spring provides the foundation for building enterprise-level applications.
- Spring Boot streamlines this process by offering defaults, auto-configuration, and embedded servers.
Think of Spring as the foundation and Spring Boot as the toolkit that accelerates development.

Advantages of Spring Boot
To summarize, here are the core advantages of using Spring Boot:
- Faster development and deployment
- Minimal boilerplate code
- Integrated testing support
- Embedded server capabilities
- Seamless integration with databases and cloud services
- Ideal for microservices and enterprise applications
Spring Boot Components
Spring Boot’s efficiency stems from its key components:
- Spring Boot Starters: Predefined dependency packages (e.g., spring-boot-starter-web, spring-boot-starter-data-jpa).
- Auto-Configuration: Automatically configures beans and properties based on the application context.
- Embedded Server: Includes Tomcat, Jetty, and Undertow for running applications without external servers.
- Spring Boot Actuator: Provides tools to monitor and manage applications.
- Spring Boot CLI: A command-line tool for building and testing applications.
These components collectively make Spring Boot efficient, quick, and production-ready.
Java Spring vs Spring Boot: Use Cases
- When to Use Spring Framework:
- Large enterprise-level applications.
- Applications requiring custom configurations.
- Projects needing fine-grained control over components.
- When to Use Spring Boot:
- Microservices and REST API development.
- Applications requiring rapid prototyping.
- Projects with tight deadlines and minimal configurations.
Conclusion - What is the Difference between Spring and Spring Boot?
To summarize, what is the difference between Spring and Spring Boot? The Spring Framework provides a comprehensive structure for Java development but involves manual configurations.
On the other hand, Spring Boot streamlines development with auto-configuration, embedded servers, and starter dependencies.
Choosing between Java Spring vs Spring Boot depends on your project requirements. If you need flexibility for complex enterprise applications, Spring is ideal. For fast, lightweight, and production-ready applications, Spring Boot is the clear winner.
Whether you’re a new developer or an experienced programmer, understanding what is Spring and Spring Boot is essential for building efficient and scalable Java applications.
FAQs About Difference between Spring and Spring Boot?
What is the main difference between Spring and Spring Boot?
The main difference between Spring and Spring Boot is that Spring is a framework for building Java-based applications with extensive manual configurations, while Spring Boot simplifies this process by providing auto-configuration, embedded servers, and starter dependencies.
What is the difference between Spring Boot and Spring Tool Suite?
Spring Boot is a tool for building production-ready Spring applications quickly, whereas Spring Tool Suite (STS) is an integrated development environment (IDE) that helps developers build and manage Spring and Spring Boot projects efficiently.
What is the difference between Spring Boot and Spring Batch?
Spring Boot is used to create stand-alone Spring applications with minimal configuration, while Spring Batch is a module within the Spring ecosystem designed for batch processing of large amounts of data, such as transaction logs or data migration tasks.
What is the difference between Spring Boot and microservices?
Spring Boot is a tool that simplifies the development of Java applications, particularly microservices, with its embedded servers and auto-configuration.
