Spring Boot is an open-source, Java-based framework used to create stand-alone, production-grade applications with the Spring platform. It simplifies the process of setting up and developing Spring applications by providing a set of opinionated 'starter' dependencies, which can automatically configure your application based on the libraries present on the classpath. This allows developers to get started quickly and with minimal configuration.
Spring Boot is designed to streamline the development process by offering the following key features:
Auto-configuration: Spring Boot can automatically configure your application based on the jars that it detects in your classpath. This reduces the need for specifying beans and allows developers to focus more on business features.
Standalone: Spring Boot applications are self-contained and can run independently without relying on an external web server. This is achieved by embedding web servers like Tomcat, Jetty, or Undertow directly into the application.
Opinionated Defaults: It comes with a set of pre-defined configurations and defaults that follow best practices, which helps in reducing boilerplate code and configuration.
Production-ready: With features like health checks, metrics, and externalized configuration, Spring Boot applications are ready for production deployment.
No Code Generation and XML Configuration: Spring Boot requires no code generation or XML configuration. It uses convention over configuration and provides a way to set up Spring applications quickly.
Spring Boot Starters: These are a set of convenient dependency descriptors that you can include in your application. For example, if you want to work with JPA, you just need to include the 'spring-boot-starter-data-jpa' starter, and Spring Boot will auto-configure Hibernate along with a sensible set of default settings.
Spring Boot CLI: This is a command-line tool that can be used for running and testing Spring Boot applications.
Actuator: Spring Boot includes a number of additional features to help you monitor and manage your app...
