Do you have practical experience working with Spring Boot?

Yes, Spring Boot is widely used for quickly creating standalone applications in Java with minimal configuration. It simplifies the setup and deployment of applications through auto-configuration and an embedded server (such as Tomcat). For example, you can create a REST service with minimal code:

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

@RestController
class HelloController {
    @GetMapping("/hello")
    public String hello() {
        return "Hello, Spring Boot!";
    }
}

Spring Boot also supports integration with databases, security, monitoring, and much more.
