BeanCreationNotAllowedException: Error creating bean with name 'eurekaInstanceCo

学习 SpringCloud 时遇到如下错误

Destroy method on bean with name 'scopedTarget.eurekaClient' threw an exception: 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!)

找了好久终于在 github 上 SpringCloud 的 issues 里找到了解决方案，链接在这里

网上也有很多文章说这样解决

@Component
public class FeignBeanFactoryPostProcessor implements BeanFactoryPostProcessor {

    @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
        BeanDefinition bd = beanFactory.getBeanDefinition("feignContext");
        bd.setDependsOn("eurekaServiceRegistry", "inetUtils");
    }
}

但我用这个方法不行。

最终的解决方案是在 pom.xml 添加 spring-boot-starter-web 依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

然后重新导入完美解决。

所用的 SpringBoot 版本：2.1.0.M2

SpringCloud 版本：Greenwich.BUILD-SNAPSHOT
