什么是Spring Boot配置以使用Cloud Foundry Service Registry（Netflix Eureka）服务？-Java 学习之路

我可以在本地设置我自己的Eureka服务器，并且可以毫无问题地注册我的服务，但是当我使用Pivotal Cloud Foundry的“Service Registry”服务创建Eureka服务器时，我的应用程序没有显示在“已注册的应用程序”下 .

我做了以下事情：

通过Cloud Foundry Marketplace创建Service Registry .
将我的应用程序绑定到该服务 .
使用该服务成功注册了我的应用程序 .

Service Registry config

我认为服务注册表是一个预先设置的eureka服务器，就像我在本地运行的服务器，但事实并非如此 .

它在幕后使用eureka，但它是一个单独的过程，需要添加下面的依赖项 .

pom.xml中：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.pivotal.spring.cloud</groupId>
            <artifactId>spring-cloud-services-dependencies</artifactId>
            <version>1.2.0.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
      ...
    </dependencies>
</dependencyManagement>
<dependencies>
    ...
    <dependency>
        <groupId>io.pivotal.spring.cloud</groupId>
        <artifactId>spring-cloud-services-starter-service-registry</artifactId>
    </dependency>
    ...
</dependencies>
