我是Spring Boot的新手,在运行我的应用程序时遇到错误.我正在关注一个教程,我相信我有适当的父母和POM的依赖,请帮助我

主要课程:

package com.boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

/**
 * Hello world!
 *
 */

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

错误是:
