在学习Springcloud微服务时，配置服务注册中心后遇到了启动内置Tomcat失败的问题。通过检查application.yml、pom.xml和程序入口类，发现启用EurekaServer注解后项目无法运行。解决方法是由于使用了Java 10，从Java 9开始模块化导致JAXB未加载，需要手动引入jaxb-api模块，从而解决了问题。

项目启动报错比调bug更加难受

概要：近日在学习Springcloud微服务。配置服务注册中心，一切妥妥当当，但还是报了一个让我崩溃的问题：org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat
翻译一下这句话：启动内置tomcat失败。
具体报错信息如下：
