Spring Boot Admin 2.0.0 Eureka 1.9.2 不显示任何应用程序

Question

我在 Eureka 服务器上运行并注册了 3 个应用程序，当我转到 http://localhost:8761/eureka/apps 时，我可以看到它们全部：

问题是，当我检查 Spring Boot Admin 网页时，它显示为空：

激活 StatusUpdateTrigger 和 DiscoveryClient 的跟踪日志我可以看到 DiscoveryClient 正在成功检索应用程序信息，但由于某种原因它们没有反映在 Spring Boot Admin 中：

de.codecentric.boot.admin.server.services.StatusUpdateTrigger trace onNext(3) 
de.codecentric.boot.admin.server.services.StatusUpdateTrigger updateStatusForAllInstances Updating status for all instances

com.netflix.discovery.DiscoveryClient refreshRegistry Completed cache refresh task for discovery. All Apps hash code is Local region apps hashcode: UP_3_, is fetching remote regions? false  

知道哪里出了问题吗？

谢谢！

我遇到了同样的问题。我可以通过将管理服务器升级到 2.0.1-snapshot 来修复

所以添加

<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-starter-server</artifactId>
    <version>2.0.1-SNAPSHOT</version>
</dependency>

然后还要添加快照仓库

<repositories>
    <repository>
        <id>sonatype-nexus-snapshots</id>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
        <url>https://oss.sonatype.org/content/repositories/snapshots/</url>
    </repository>
</repositories>
