BeanCreationNotAllowedException: Error creating bean with name 'eurekaInstanceCo

学习 SpringCloud 时遇到如下错误

代码语言：javascript复制

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

代码语言：javascript复制

@Component
public class FeignBeanFactoryPostProcessor implements BeanFactoryPostProcessor {

<span class="hljs-meta">@Override</span>
<span class="hljs-function"><span class="hljs-keyword">public</span> <span class="hljs-keyword">void</span> <span class="hljs-title">postProcessBeanFactory</span><span class="hljs-params">(ConfigurableListableBeanFactory beanFactory)</span> <span class="hljs-keyword">throws</span> BeansException </span>{
    BeanDefinition bd = beanFactory.getBeanDefinition(<span class="hljs-string">"feignContext"</span>);
    bd.setDependsOn(<span class="hljs-string">"eurekaServiceRegistry"</span>, <span class="hljs-string">"inetUtils"</span>);
}

}

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

代码语言：javascript复制

<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

spring springcloud
