我是Spring Boot的新手，运行应用程序时出错。我正在学习一个教程，我相信我对POM有正确的父母和依赖关系，请帮助我

主类：

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：

   org.springframework.boot.context.embedded.EmbeddedServletContainerException: Unable to start embedded Tomcat servlet container
        at org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainer.start(TomcatEmbeddedServletContainer.java:165) ~[spring-boot-1.3.1.RELEASE.jar:1.3.1.RELEASE]

回答：

尝试将application.yaml（或application.properties）中的端口号更改为其他名称。
