spring boot actuator endpoints not activated

I am learning Spring boot Actuator, notice that spring boot actuator not getting activated. I am following the documentation [spring docs][1], so adding the maven dependency as mentioned.

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
</dependencies>

My POM.xml:

</project>

My Spring application:

package net.javapedia.springscheduling;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class SpringSchedulingApplication {

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

}

application.properties

management.endpoints.enabled-by-default=true

Console output:

I am trying to access the actuator health endpoint at http://localhost:8080/actuator/health but no luck.

Please add the following to your pom.xml:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

I've copied your setup and it really didn't work initially. But it worked out after I've added spring-boot-starter-web. It seems that you have to have web dependencies to spin up any controller, not only app-specific but even actuator's.

App log:
