创建名为“eurekaInstanceConfigBean”的bean时出错:在此工厂的单个程序被破坏时不允许单例bean创建

Question

这个问题是Working With Eureka Clients Programmatically issue - Completed shut down of DiscoveryClient的扩展。在我的windows机器上，JAVA_HOME和PATH都是不同的版本。我刚刚改正了它，现在它给我显示了下面的错误。

错误：

在名为“while edTarget.eurekaClient”的bean上调用破坏方法失败: org.springframework.beans.factory.BeanCreationNotAllowedException:错误创建名为“eurekaInstanceConfigBean”的bean :在此工厂的单节点被破坏时不允许单例bean创建(不要在破坏方法实现中从BeanFactory请求bean！)

我已经看过了urls，比如:Error creating bean with name and Singleton bean creation not allowed和https://github.com/spring-cloud/spring-cloud-netflix/issues/1064，但是这些建议还不清楚。

完整的错误跟踪：

您只需添加web依赖项即可。我不清楚为什么添加了、web、依赖/解决了这个问题。
