Spring-boot application not getting auto-deployed on startup

Question

I created a spring boot basic application in Eclipse IDE by following a tutorial online. When I am trying to run the application as a java application, the application is not getting deployed in embedded tomcat. I have googled a lot and tried some of the found solutions. However, none worked for me. I am pasting the code here. Please let me know any possible issues. Code:-

pom.xml:-

SpringBootExample.java:-

package com.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.test.config.AppConfiguration;

@SpringBootApplication
public class SpringBootExample {

    public static void main(String[] args) {
        System.out.println("Started main");
        SpringApplication.run(AppConfiguration.class, args);
        System.out.println("Ending main");
    }

}

AppConfiguration.java:-

package com.test.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.test.beans.SampleBean;

@Configuration
public class AppConfiguration {

    @Bean
    public SampleBean getSampleBean() {
        return new SampleBean();
    }
}

SampleBean.java:-

package com.test.beans;

public class SampleBean {

    public SampleBean() {
        System.out.println("In constructor of SampleBean");
    }

}

Please note that bean of type SampleBean is getting created.But, application is closed after that. Below are the output logs:-

Answer 1

I added the annotation @EnableAutoConfiguration to AppConfiguration.java and it started working. The application was not able to determine which type of ServletWebServerFactory to create. After adding above annotation, it created it for embedded tomcat already present in classpath.
