关于解决搭建Eureka出现的Unable to start embedded Tomcat；无法启动嵌入式tomcat异常

今天在搭建Eureka的时候，死活都跑不起来！一直提示 Unable to start web server; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat；无法启动嵌入式tomcat；
pom如下：

application.yml配置

server:
port: 10086 # 端口
spring:
application:
name: eureka-server  # 微服务在容器中的名称，会在Eureka中显示
eureka:
client:
service-url:     # EurekaServer的地址，现在是自己的地址，如果是集群，需要加上其它Server的地址。
defaultZone: http://127.0.0.1:${server.port}/eureka

引导类：

@SpringBootApplication
@EnableEurekaServer  //声明当前springboot应用是一个eureka服务中心
public class ItheimaEurekaApplication {

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

此问题困扰了一下午，各种调试都无法解决；后来终于发现，是使用jdk版本的问题；
我使用的是java9版本，在java8及之前内置了jaxb-api包，但是java9及之后就没有引入这个包了，所以需要在pom中手动引入，如下配置文件。

<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>

在Spring Cloud官方也指出了：

在pom文件中做出如下配置，问题解决！！

<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency><dependency>
