What is Spring Boot? Understanding its Definition and Features

In recent years, Spring Boot has become a widely popular and essential framework for developers, simplifying the process of creating and deploying applications. About 43% of professional developers use this tool to build APIs for application development. This glossary page will provide you with a comprehensive understanding of Spring Boot, its benefits, use-cases, best practices, and the most recommended books for in-depth knowledge.

“Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can just run.” – Pivotal Software

What is Spring Boot? Definition of Java Spring Boot

Spring Boot is an open-source Java-based framework designed to help developers create stand-alone, production-grade Spring applications with minimal effort. It was created by the Pivotal Team as an extension to the Spring Framework, aiming to simplify the complete process of app development, from writing code to deployment and execution. With Spring Boot, developers can easily build microservices, RESTful web services, and other types of applications using the Java programming language.

How it Works

Spring Boot works by automating configuration, dependency management, and bootstrap processes, providing production-ready defaults for application development. This way, it helps developers to focus on writing business logic instead of wasting time on configuring dependencies and other configurations manually. It offers various embedded server options like Tomcat, Jetty, and Undertow, which means that the applications developed using Spring Boot can run as stand-alone applications directly from the command line or an executable JAR file.

Key features of Spring Boot:

• Auto-configuration: Automatically configures commonly used application features and beans according to the included dependencies on the classpath.
• Standalone execution: Runs without requiring an external container by using embedded servers like Tomcat or Jetty.
• Production-ready tools: Includes non-functional essentials like metrics, health checks, and configuration management.
• Extensible: Offers extensibility by allowing developers to override default configurations and implement custom features if required.

Benefits of using Spring Boot

• Quick development: Spring Boot simplifies the entire process of app creation, enabling developers to develop applications more efficiently.
• Reduced configuration: Auto-configuration eliminates the need for manual XML or Java-based configuration, saving time and effort.
• Embedded server container: Allows developers to run applications directly as an executable, without depending on external servers.
• Easy dependency management: With starters, developers can include and manage dependencies easily, reducing the chances of version conflict.
• Built-in featured templates: Spring Boot includes various featured templates, allowing developers to build web applications or APIs with minimal coding.
• Community and ecosystem support: Since Spring Boot is backed by Pivotal, it has excellent community and ecosystem support, offering numerous plugins and integrations.

Spring Boot use cases

Spring Boot has a wide range of use-cases, making it suitable for various types of application development. Some of the most common use-cases include:

• Microservices development: It is highly useful for developing and deploying independent, scalable, and resilient microservices.
• RESTful web services: It simplifies the creation of RESTful web services with built-in support for JSON, XML, and various HTTP methods.
• Web applications development: Integrates with various web frameworks and UI technologies like Thymeleaf, JSP, and Angular for building web applications.
• Big data and analytics projects: Spring Boot assists in creating powerful data-driven applications with easy integration of various data analysis and reporting tools.
• Enterprise applications: Offers a secure platform for developing and deploying complex and scalable enterprise applications.

Code Examples

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MySpringBootApplication {

    public static void main(String[] args) {
        SpringApplication.run(MySpringBootApplication.class, args);
    }
}

Best Practices

To maximize productivity while working with Spring Boot, it’s essential to follow some best practices. Always choose the proper packaging structure for your project, such as using the default Maven or Gradle structure. Make use of the Spring Boot Starter features to manage dependencies and reduce boilerplate code. Leverage the power of Actuator to monitor and manage your application’s health, metrics, and environment. Utilize pre-defined production-ready configurations and override them as needed to customize your application. Lastly, ensure that you take advantage of the extensive community support and resources available for Spring Boot.
