What Is Java Spring Boot?

Java Spring Boot is a widely used open-source framework built on top of the Spring Framework, which is designed to simplify the development and deployment of Java-based applications, particularly microservices and web applications. It is created and maintained by Pivotal Software, now a part of VMware.

Spring Boot aims to streamline the development process by providing pre-configured templates, called “starters,” which handle common tasks like setting up a database connection, configuring a web server, or enabling security features. These starters allow developers to focus on writing their application logic rather than spending time on configuring the underlying infrastructure.

Some key features of Spring Boot include:

1. Convention over configuration: Spring Boot relies on sensible defaults and conventions that minimize the amount of configuration required to set up a new project. This helps developers get started quickly and reduces the boilerplate code.
2. Standalone applications: Spring Boot enables developers to create standalone, executable Java applications with an embedded web server (like Tomcat, Jetty, or Undertow). This allows for easy deployment without the need for a separate application server.
3. Autoconfiguration: Spring Boot automatically configures your application based on the dependencies you’ve added to your project. This helps to minimize manual configuration and setup.
4. Dependency management: Spring Boot provides pre-configured sets of dependencies, ensuring compatibility between different components and simplifying the process of adding new dependencies to your project.
5. Actuator: Spring Boot Actuator provides production-ready features, such as monitoring, health checks, and application metrics, making it easier to manage applications in production environments.
