启动日志错误信息如下：
Invocation of destroy method failed on bean with name 'scopedTarget.eurekaClient': org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'eurekaInstanceConfigBean': Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)
继续向上查看日志，发现日志中有以下内容：
Caused by: java.net.BindException: Address already in use: bind
原因很明显，服务端口被占用了！
解决方法：
方法1、将服务端口修改为未被使用的端口
方法2：参照 ------解决端口被占用问题------ 这篇文章，终止占用端口的进程，释放端口既可。
