SpringCloud客户端启动报错
·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!)
Registering application UNKNOWN with eureka with status UP
DiscoveryClient_UNKNOWN/DESKTOP-MQ8D0C9:8761 > - was unable to refresh its cache! status = Cannot execute request on any known server
项目启动后自动停止，在控制台没看到启动的端口，估计是没有引入spring boot的web包
在pom文件中引入如下

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId </dependency> |
重启解决问题。
以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。
