Is Spring Boot a Web Server?

When it comes to building web applications, Spring Boot is a popular choice among developers. But is Spring Boot a web server? Let’s dive into this topic and find out.

Understanding Web Servers:

Before we can answer the question, let’s first understand what a web server is. A web server is a software or hardware that serves content over the internet. It receives requests from clients (such as web browsers) and responds with the requested resources.

Spring Boot as a Web Framework:

Spring Boot, on the other hand, is not a web server itself but rather a framework for building Java-based web applications. It provides several features that make it easier to develop robust and scalable web applications.

Embedded Tomcat Server:

One of the key features of Spring Boot is its ability to embed an application server such as Apache Tomcat directly within your application. This means that you don’t need to deploy your application to an external server, as the embedded server can handle incoming requests.

Advantages of Using Spring Boot for Web Development:

  • Simplified Configuration: With Spring Boot, you can avoid complex XML configurations typically associated with Java-based web applications. It uses convention over configuration principles, making it easier to get started.
  • Rapid Development: The framework provides a range of pre-built components and libraries that help speed up development.

    This includes features like auto-configuration, which automatically sets up common configurations based on dependencies in your project.

  • Built-in Security: Spring Security is another powerful feature of Spring Boot, providing robust security capabilities out of the box. It allows you to secure your web application with minimal effort.
  • Microservices Support: Spring Boot is well-suited for building microservices-based architectures. It provides features and integrations that make it easier to develop, deploy, and manage microservices.


While Spring Boot is not a web server itself, it provides an embedded server capability that allows you to run your Java-based web applications without the need for an external server. Its simplified configuration, rapid development features, built-in security, and support for microservices make it a popular choice among developers for web development projects.

In summary, Spring Boot complements existing web servers by providing a framework that simplifies the development process and enhances productivity. Whether you are building a small-scale application or a large-scale enterprise system, Spring Boot can be an excellent choice.
