Spring Boot is an open-source framework used for developing web applications. It is a part of the Spring Framework and provides the opportunity to develop applications quickly by reducing complexity. Its features include an embedded web server, automatic configuration, dependency management, and monitoring interface. Starter packages offer developers the ability to write less code and develop applications faster.
Spring Boot is an ideal choice for microservices and cloud-based applications. The microservices architecture breaks down large applications into smaller, more manageable pieces. Spring Boot offers features that support this architecture and make application scaling easier.
This code is used to start a Spring Boot application, one of the most basic components. The tag indicates that the application is a Spring Boot application and is called by the application launcher. Spring Boot starts the server and runs the application.
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class MyApplication {
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
}This code is one of the most essential components needed to start a Spring Boot application. The @SpringBootApplication annotation specifies that the application is a Spring Boot application and is called by the SpringApplication.run method of the application launcher. This way, Spring Boot automatically starts a server and runs the application.
