Request execution failed with message: java.net.ConnectException: Connection refused: connect

回答: 这个错误是由于请求执行失败导致的，错误信息是java.net.ConnectException: Connection refused: connect。根据引用\[1\]，可能的原因是Eureka的Server没有启动。在使用@EnableDiscoveryClient或者@EnableEurekaClient之后，客户端会自动去寻找Eureka Server，如果找不到就会报这个错。所以请确保Eureka Server已经启动。如果是布置了Eureka集群，还需要在C:\Windows\System32\drivers\etc目录下的hosts文件中添加相应的配置，如引用\[3\]所示。
