Top 5 Essential Spring Boot Features for Java Development

You’ve probably heard regarding Spring Boot and its miraculous ability to construct a Spring Web application in less than 140 characters, but what exactly does that necessarily imply? 

What exactly are these characteristics that give Spring Boot so much power while also making Spring boot developers application development so simple? That is what you will discover in this post. 

We’ll go through the auto-configuration, starting requirements, Spring Boot CLI, and Actuator and Spring Initializer capabilities in further depth. 

These are the characteristics that alleviate the greatest amount of pain and friction that comes with developing Spring-based Java web applications.

  • AutoConfiguration

This is not very difficult for a person who has previously developed in Spring, but it might take hours or days to discover out if you are beginning from scratch. But, more crucially, regardless of our application, this is a piece of code that numerous of us have written. I mean, this functionality is not exceptional, and it will be required by every Spring boot developer application that uses JDBC.

Here’s where the Spring Boot AutoConfiguration function comes in. It recognizes the existence of a certain Class in the Classpath and then customizes it for you. 

You may have dealt with Spring-based Java web applications that connect to a database system, such as an in-memory registry such as H2, and if so, you may be aware that you must declare the JdbcTemplate as a bean as well as setup a DataSource, which is a requirement for the JDBC template. 

In order to use Java-based customization in a contemporary Spring application, you must add the following 2 techniques to your Settings class:

  • Starter POMs

You can access all of these by just including the spring-boot-starting-web requirement in your pom.xml if you use Spring Boot Beginning POMs or the starter requirement functionality. 

So, so rather than adding all of these requirements and worrying about compatibility, you only need to add one. 

You will also have more confidence that proven and tested library versions are being utilized, and that there will be no interoperability issues in the future.

Another inconspicuous advantage of the beginning POMs feature is that you don’t have to remember or look for dependencies. 

You can include a ‘web’ beginning if you are creating a web application. If you’re developing a Spring boot developers JPA application, you may include the ‘JPA’ beginning by combining common requirements and features that Spring Boot has made simple to understand.

  • Spring Boot CLI

The Spring Boot CLI is a graphical interface offered by the Spring Boot framework that allows you to develop Spring-based web apps in Groovy. Groovy and Spring Boot possibly work well together. 

Groovy strives to simplify Java programming, whereas Spring Boot simplifies Spring application development and both benefits from each other’s simplification. 

Spring CLI is an expanded version of Spring Boot, whereas vehicle and starting requirements are required. In order to utilise it, you must also install Spring CLI.

  • Actuator

The actuator seems to be another fantastic Spring Boot feature that allows you to monitor what’s going on within a functioning Spring boot developer’s application. 

With all of the benefits of auto-configuration comes the risk of not understanding what is within your program, which is handled by the Spring Actuator.

It offers a wealth of information and data about running apps in production. An actuator, for example, may be used to determine which objects are configured in the Application environment, what vehicle decisions will be made, what environmental parameters, system attributes, and command line arguments are exposed to an application and many other things.

  • Spring Boot Initializer

Spring Innovative opportunities is another Spring Boot component that addresses the issue of the project plan. 

It’s a web software that lets you create Maven or Gradle applications in Java, Kotlin, Groovy, or Spring Boot.

All you are required to do is supply the Project MetaData in the GUI, such as the description of your project, Group, Artifact, and so on. 

It also lets you select a beginning requirement from a long selection, such as web, JPA, or secure beginning.

The Spring Authorization application is available for download. After creating a project, you may download the Zip file and open it in an IDE such as Eclipse or IntelliJ IDEA. You may then modify this document to fit your needs.
