What is Spring Boot?

Spring Boot is a popular Java-based framework used to build web applications and microservices. It is built on top of the Spring framework and provides a set of features and tools that make it easy to create and deploy web applications quickly.

One of the main advantages of Spring Boot is its ability to automatically configure and manage many of the components and dependencies required for a web application.

This eliminates the need for developers to manually configure and manage these components, which can save a significant amount of time and effort.

Spring Boot also provides a number of features to help developers create web applications quickly and easily. These include:

Embedded web servers

Spring Boot can automatically configure and start an embedded web server (such as Tomcat or Jetty) when the application is run, eliminating the need to manually configure and start a separate web server.

Auto-configuration

Spring Boot can automatically configure many of the components and dependencies required for a web application, such as databases, security, and caching.

Command-line interface

 Spring Boot provides a command-line interface that can be used to quickly generate a new project, run the application, and perform other tasks.

Actuator

Spring Boot includes an Actuator that provides a number of endpoints to monitor and manage the application, such as health checks and metrics.

In addition to these features, Spring Boot also provides a number of plugins and starters that can be used to add functionality to an application, such as security, data access, and messaging.

Spring Boot is often used to build microservices, which are small, independent services that can be easily deployed and scaled. Spring Boot provides a number of features and tools that make it easy to create and deploy microservices, such as service discovery, load balancing, and circuit breaking.

Overall, Spring Boot is a powerful and flexible framework that can help developers create web applications and microservices quickly and easily. Its ability to automatically configure and manage many of the components and dependencies required for a web application, as well as its many features and tools, make it a popular choice for many developers.
