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
