原因：
根本原因是关闭ApplicationContext时，它将销毁所有单例bean，eurekaAutoServiceRegistration首先销毁，然后销毁feignContext。销毁feignContext时，它将关闭与每个FeignClient关联的ApplicationContext。由于eurekaAutoServiceRegistration监听ContextClosedEvent，因此这些事件将发送到该bean。不幸的是，由于它已被销毁，因此我们得到了上述异常（尝试在销毁中创建bean）。
解决方法：
@Component public class FeignBeanFactoryPostProcessor implements BeanFactoryPostProcessor { @Override public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException { if (containsBeanDefinition(beanFactory, "feignContext", "eurekaAutoServiceRegistration")) { BeanDefinition bd = beanFactory.getBeanDefinition("feignContext"); bd.setDependsOn("eurekaAutoServiceRegistration"); } } private boolean containsBeanDefinition(ConfigurableListableBeanFactory beanFactory, String... beans) { return Arrays.stream(beans).allMatch(b -> beanFactory.containsBeanDefinition(b)); } }
