Springboot is a framework that built based upon the spring framework. With the help of Spring Boot, we can develop and deploy Java based web applications, including microservices, very easily.

 

This spring boot framework enables the development of executable JAR files that are self-contained. in place of conventional WAR or EAR files. This implies that you, as a developer, should concentrate solely on your business logic and the framework will be responsible for the initialisation of your application and the packaging of your application. and deploying your application into an embedded Tomcat server or embedded web server. 

Therefore, the files that we will produce with the assistance of these Spring Boot applications are self-contained, which implies that they will have all the necessary dependencies to function. 

 

 

Advantage of Springboot 

• Springboot  approach eliminates the need of external web server like Tomcat or JBoss or any other application servers. And we don't have to maintain all of them manually.
• Springboot  provide a lot, many built in features and integrations with the help of concepts like auto configuration dependency injection, and it also supports various cloud platforms.
  • As soon as you're trying to create a web application with Spring boot framework, it is going to make auto configurations to deploy your web application into a web server like Tomcat at a default port of 8080.
  • As a developer, you can always override them with the help of properties inside the spring boot framework.
• Whenever we are using Spring Boot framework, it provides an embedded service like Tomcat, Jetty or Undertow, which you can use to run your microservices directly without the need of a separate server, installation and maintenance.
• Spring boot framework supports a lot many production ready features, such as providing metrics about your web application, health monitoring and external configurations.
  • Earlier Inside monolithic approach, we as a developer need to write lot of code to monitor our web application, to produce metrics from our web application and to configure some external configurations. Whereas with Spring Boot, everything is going to be super, super easy with the dependencies like spring boot actuator.
• With  Springboot we can quickly bootstrap a microservice project and start coding with range of started dependencies, that provide pre configured settings for various components such as database, queue etc. 
  • Before Spring Boot whenever a developer wants to add a dependency related to some database or some message queues or some other framework, you need to do a lot of configurations inside his project and he need to add a lot of dependencies manually.
  • But with the help of starter projects inside Spring Boot, it is going to be super, super easy. You as a developer just tell what dependencies you have inside your web application. Suppose if I'm trying to connect to a MySQL database, I can define that and my spring boot is going to provide a starter project which will have a bundle of dependencies that will help me to connect with my MySQL database.
• Whenever we are building applications with the help of springboot microservices.  They are cloud ready, which means you can easily deploy them into any cloud platforms like Kubernetes, you can containerize your application with the help of Docker, you can easily deploy them into cloud providers like AWS, GCP, Azure.
