Spring Boot is a Java framework based on the Spring framework. Spring Boot has an opinion about the Spring platform and helps you build Java applications quickly without writing multiple lines of boilerplate code. Most Spring Boot applications require minimal Spring configuration. Join FITA Academy‘s Spring and Hibernate Training in Chennai.

The auto-configuration feature attempts to configure your Spring application automatically based on the jar dependencies you have added, making application development very convenient for Java developers.
The following are some Spring Boot Features for Java Developers should be aware of:
Spring Boot Features
Spring Initialize
Spring Initializr is a tool for getting your Spring Boot projects up and running. This Spring Boot feature facilitates project creation via cURL, multiple IDEs, and its own Spring CLI. It generates no application code but does provide a basic project structure. All that remains is to write the application code.
Spring Initializr allows you to choose a project, a programming language, and dependencies such as dev tools, actuators, web, etc. After selecting the choices on the Spring Initializr screen, click the button to create a project.
Spring CLI
The Spring Boot CLI is a command-line tool for quickly developing a Spring application. You can use Spring CLI to execute Groovy scripts, allowing you to code using your Java knowledge without having to write reusable code repeatedly. You can begin a new project by utilizing the starter component, which resolves dependencies.

Externalized Configuration
All configuration parameters in Spring Boot applications are read from the application.properties or application.yaml resource files. However, you may need to transfer your configuration from one environment to another. This is when you must configure these properties, necessitating rebuilding and testing your application in all environments. Not only that, but you must redeploy your application in the production environment every time a change occurs.
To address this issue, Spring Boot allows you to externalize your configuration. Externalizing configuration entails using the application code that you use in one environment in another. Spring Boot allows you to extend your configuration and reuse your code in various environments.
To externalize the configuration, use the following files:
- Properties files
- YAML files
- Environment variables, etc.
Autoconfiguration
Assume you want to create a new library that will be used throughout your application. You may be able to develop and integrate the code; however, you may still be required to perform a significant amount of configuration manually. The autoconfiguration feature provided by Spring Boot comes into play here.
Spring Boot allows you to select dependencies for your project while creating a new project. The autoconfiguration feature loads specific default configurations based on these dependencies. The AutoConfiguration class is fortified with @Conditional annotations, which activate beans under specific conditions. During an application’s startup, Spring Boot evaluates these conditionals.
