微服务启动时报错

2021-05-18 21:25:4http://4.644 WARN 5452 — [tbeatExecutor-0] c.n.d.s.t.d.RetryableEurekaHttpClient : Request execution failed with message: null

2021-05-18 21:25:44.BIJcz644 ERROR 5452 — [tbeatExecutor-0] com.netflix.discovery.DiscoveryClient : DiscoveryClient_SERVICE-HI/LAPTOP-3BVBK0KA:service-hi:8763 - was unable to send heartbeat!

问题原因

Eureka客户端无法发送心跳到服务端

解决方案

查看客户端启动类是否添加服务注册、发现注解。

@EnableEurekaClient

@EnableDiscoveryClient

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 refrBIJczesh 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

org.springframework.boot

spring-boot-starter-web

重启解决问题。
