The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications — on any type of deployment platform.

What is SpringBoot?

Spring Boot is a lightweight framework that takes up most of the work in configuring Spring-based applications. The main goal of the Spring Boot Framework is to reduce overall development time and increase efficiency by having a default setup for unit and integration tests.

In short, Spring Boot is the combination of Spring Framework and Embedded Servers.

In Spring Boot, there is no requirement for XML configuration (deployment descriptor). It uses convention over configuration software design paradigm that means it decreases the effort of the developer.

We can use Spring STS IDE or Spring Initializr to develop Spring Boot Java applications.

Why Spring Boot?

You can choose Spring Boot because see the features and benefits:

  • It provides a flexible way to configure Java Beans, XML configuration, and database transactions.
  • It provides powerful batch processing and manages REST endpoints.
  • In Spring Boot, everything is autoconfigured; No manual configuration is required.
  • It provides an annotation-based Spring application
  • Makes dependency management easy
  • Includes Embedded Servlet Container.

Why is Springboot is important in a Programming language?

Spring Boot helps developers build applications that just run. Specifically, it lets you create standalone applications that run on your own, without relying on external web servers, by embedding a web server like Tomcat or Netty in your app during the initialization process.

Where can you use a spring boot?

The spring boot provides a good platform to develop stand-alone and production-grade spring applications for Java developers that you can still run. You can get started with minimal configuration without requiring the entire spring configuration setup.

What is the Benefits of Springboot?

  • Fast and easy development of Spring-based applications.
  • No need for the deployment of war files.
  • The ability to create standalone applications.
  • No need for XML configuration.
  • Reduced amounts of source code.

Spring Application —

The SpringApplication is a class that provides a convenient way to bootstrap a Spring application. It can be started from the main method. We can call the application just by calling a static run() method.

public static void main(String[] args)


SpringApplication.run(ClassName.class, args);


Application Events and Listeners —

Spring Boot uses events to handle the variety of tasks. It allows us to create factories file that is used to add listeners. We can refer it to using the ApplicationListener key.

Always create factories file in META-INF folder like META-INF/spring.factories.

Admin Support —

Spring Boot provides the facility to enable admin-related features for the application. It is used to access and manage applications remotely. We can enable it in the Spring Boot application by using spring.application.admin.enabled property.

Externalized Configuration —

Spring Boot allows us to externalize our configuration so that we can work with the same application in different environments. The application uses YAML files to externalize configuration.

Properties Files —

Spring Boot provides a rich set of Application Properties. So, we can use that in the properties file of our project. The properties file is used to set properties like server-port =8082 and many others. It helps to organize application properties.

YAML Support —

It provides a convenient way of specifying the hierarchical configuration. It is a superset of JSON. The SpringApplication class automatically supports YAML. It is an alternative of properties file.

Type-safe Configuration —

The strong type-safe configuration is provided to govern and validate the configuration of the application. Application configuration is always a crucial task which should be type-safe. We can also use annotation provided by this library.

Logging —

Spring Boot uses Common logging for all internal logging. Logging dependencies are managed by default. We should not change logging dependencies if no customization is needed.

Security —

Spring Boot applications are spring bases web applications. So, it is secure by default with basic authentication on all HTTP endpoints. A rich set of Endpoints is available to develop a secure Spring Boot application.
