    微服务启动时报错

    2021-05-18 21:25:44.644 WARN 5452 — [tbeatExecutor-0] c.n.d.s.t.d.RetryableEurekaHttpClient : Request execution failed with message: null

    2021-05-18 21:25:44.644 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 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。
