Spring Netflix Eureka服务器以非法URL从intelliJ启动

易雅畅
2023-03-14

我用Spring-Cloud-Netflix-Eureka-Server启动了一个应用程序。在启动时，它运行到java.net.UriSyntaxException中。我只在start.spring.io-bootstrap之后添加了@enableeurekaserver。

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurekaserverApplication {
  public static void main(String[] args) {
      SpringApplication.run(EurekaserverApplication.class, args);
  }
}

我们可以看到问题：服务器尝试从urlhttp://gersee my company:8080开始。为什么不在localhost简单地开始呢？我该怎么修好它？如果我运行一个spring-boot-webapp，其中包含一个没有eureka的控制器，它将从localhost启动。

它看起来像是从yout主机文件中得到了错误的主机名。

类SimpleDiscoveryClientAutoConfiguration创建设置主机的beanSimpleDiscoveryProperties。

@Bean
public SimpleDiscoveryProperties simpleDiscoveryProperties() {
    SimpleDiscoveryProperties simple = new SimpleDiscoveryProperties();
    simple.getLocal().setServiceId(this.serviceId);
    simple.getLocal()
            .setUri(URI.create(
                    "http://" + this.inet.findFirstNonLoopbackHostInfo().getHostname()
                            + ":" + findPort()));
    return simple;
}

方法findFirstNonLoopBackHostInfo()提供主机名。您可以提供您的bean，并根据您的偏好设置主机名。我不知道有没有更简单的方法可以做到这一点。

编辑：

您可以尝试使用spring.cloud.inetutils.ignoredinterfaces属性忽略错误选择的接口。或者只需将eureka.instance.hostname设置为localhost。
