Everything you need to know about Spring Boot before getting Started!

Let us start with the very basic definition of a Spring Boot.

It is an amazing technology that provides an easier and faster way to set up, configure and run any web-based application. One of the best things of Spring Boot is that it smartly chooses all your dependencies and auto-configures all the features that are on your priority list so that you can easily start your application in just a single click. Not only this, but it also simplifies the deployment process of your application.

Do you want to know how?

Spring Boot by default uses an embedded server that eliminates the need of Java EE containers. You can expose its components such as REST services independently so that you need not redeploy all its consumers at the time of maintenance.

However, if you want to run a web-based application using Spring Boot, firstly you should understand the components of Spring boot to get a kickstart. Let’s get started!

What is Actually a Spring Boot?

Spring Boot can be explained in just a single line:

( Spring Framework – XML Configuration ) + Integrated Server.

Components of Spring Boot

Spring Boot Auto Configure

Spring boot has the ability to detect the availability of certain frameworks such as Spring Data JPA, Spring Batch, Hibernate, and JDBC. Once it has detected the framework, it will auto-configure it.

Spring Boot Core

Spring Boot core is a base for other Spring models. It provides certain functionalities that work on their own with validation.

Spring Boot CLI

It is basically a command line interface based on ruby and rails for its function. However, to start and stop the application, spring boot is required.

Spring Boot Actuator

Spring Boot Actuator enables certain enterprise features that you can use in your application. It can auto-detect frameworks and features of your application and use it accordingly as and when required.

Spring Boot Starters

Starters help to initiate the project and are included as a dependency in your built file. It automatically adds starter projects and dependencies for the kind of application you’re using.

Features of Spring Boot

Intelligent Auto-Configuration

One of the best features of Spring Boot is that it auto configures your application according to your dependencies. It is not only smart and active but also contextually smart and keep a note of your requirements. Let us take the example of a database feature. In case you have added a requirement to a pom.xml, which somehow relates to a database, Spring boot assumes by itself that you would like to use a database and thus it allows your application to make use of the exact database anytime.

Being Standalone

Spring boot allows you to design stand-alone, production-grade quality applications that you can run on any website without wasting time. You might think that running a java application is extremely simple and easy. All you need to do is give a run command and everything starts happening exactly what you have thought of. Honestly, this is not true! To run a java application following steps are required:

  • Package your application
  • Choose which type of web server you want to run your application and download it
  • Configure that web server
  • Organize the deployment process

However, if you’re using Spring Boot technology to run your application, you just need to follow two steps:

  • Package your application
  • Run it using some simple commands such as java -jar my-application.jar

How simple is that! Spring Boot takes care of the rest of your requirements by simply configuring and deploying an embedded web server to your application.

Opinionated

The best thing about using Spring Boot is that it takes an opinionated view before it starts building or deploying new Spring application. When developers use Java, they are full of choices whether it is related to logging and collecting framework or building a tool. Instead of having so many choices in Java, developers like to use only the popular libraries.

Spring Boot, on the other hand, loads and configures those libraries in the most standard way. That’s the reason, developers get more time to configure and write the code over and over again. Thereby, satisfying business needs. Using Spring Boot, you can easily select what you want and get along with ready-to start application for yourself in just a few clicks!

Difference Between Spring Boot vs. Spring MVC vs. Spring

Understanding the difference between Spring Boot, Spring MVC and Spring is of utmost importance. A lot of people who have little knowledge of Spring Boot get confused when it comes to using and deploying these three Spring technologies. Therefore, it becomes extremely important to know when and where they are used.

  • Spring Framework: The role of Spring Framework is of giving a dependency which is also known as Inversion of Control (IOC). when IOC is used appropriately, it helps in developing loosely coupled applications which can be easily tested and used.

 

  • Spring MVC: It provides a decoupled way of designing web applications. With simple concepts such as View Resolver, Dispatcher Servlet, and ModelAndView, it enables developers to develop applications without consuming much time.  

 

  • Spring Boot: Spring Boot works smartly by auto-configuring the data sources. It can handle starter projects too which increase productivity and reduces developers’ effort by eliminating the need of writing annotations, boilerplate Code, and XML Configuration.

Wrapping Up

Now that you know enough about Spring Boot you can easily make out a difference with other technologies. Moreover, when you start using it, you will be overwhelmed with its performance and the way it knows all your choices and dependencies that not only save your time but also allows you to work efficiently.
