How does Spring Boot facilitate the acceleration and simplification of application development based on Spring?

Spring Boot significantly simplifies and accelerates the development of Spring-based applications through the following features:

• Automatic configuration: Spring Boot automatically configures many application components based on project dependencies, eliminating the need to write a lot of configuration code.

• Embedded application server: you can run the application as a standalone jar with an embedded Tomcat or Jetty, which simplifies deployment and testing.

• Starter dependencies: a set of ready-made dependencies for popular functions (e.g., web, data, security), which are easy to include and use immediately.

• Convenient development tools: support for hot reloading, Actuator for monitoring, simplified management of settings via application.properties/yml.

Example:

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

This minimal code launches a full Spring application without additional configuration.
