Spring boot 在随机端口上运行微服务时，Eureka无法找到端口

我正在使用eureka进行服务发现，并在spring boot应用程序中使用ribbon进行负载平衡。当我在固定端口上运行向eureka注册的micro服务时，它工作正常，但当我在随机端口上运行它们时，尽管我可以看到在eureka仪表板上注册的服务，但它无法找到端口号。当我尝试点击服务时，我得到了以下错误

我的服务已在eureka注册，名称为MYAPP。我还尝试了打印url，如您所见，它提供

http://nawnit:8080

在固定端口上运行时，但在随机端口上运行时，我得到

http://nawnit:0

（nawnit是我的电脑名）

这是我的eureka服务器配置属性。

public ResponseEntity<BaseResponse> verifyEmail(@RequestBody CustomerIdentity identity,
            @PathVariable Integer simID) throws HttpClientErrorException {
        System.out.println(this.discoveryClient.getInstances("MYAPP").get(0).getUri().toString());
        return restTemplate.postForEntity("http://MYAPP"+ "/validation/" + simID, identity, BaseResponse.class);
    }

server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
logging.level.com.netflix.eureka=OFF
logging.level.com.netflix.discovery=OFF

注意：我使用的restTemplate配置为负载平衡。

这是一个错误，已经修复。有关重新创建问题的测试，请参阅。这里也进行了修复

---

这将于下周（2018年12月6日）作为Greenwich.RC1的一部分提供。请参阅以获取更新。

从ribbon starter中删除该版本，并将其更改为

spring cloud starter netflix ribbon

，然后重试。我会尝试。但ribbon与eureka有任何关系吗？因为如果你看到print语句，它使用doscoverycinet来获取url，我想它独立于ribbon，对吧？这是一个bug。关注进展。@Spencergib谢谢。只是出于好奇你是怎么知道它是个虫子的？我的意思是，你是如何确定它是一个bug的？我不怀疑你，我只是想知道。创建了一个项目，它像你的一样失败了，改为Finchley.SR2有效，所以我知道这是一个回归。现在我们有一个测试来检查它。所以一旦它被发布，那么只有我才能拥有更新的代码？如果我克隆了存储库，它会工作吗？我想它有你的更改？你可以这样做，但我们也将快照部署到repo.spring。io@NawnitSen与此同时，坚持使用spring cloud starter netflix eureka客户端2.0。2@MartinSchröder除了boot2.1不起作用之外。x@spencergibb这就是我回到SpringBoot2.0.x的原因
