我正在开发spring-cloud-boot-admin示例。在这个例子中，我什么也没做，但项目仍然无法启动。如果我将 spring-boot-starter-parent 降低到1.5.4.RELEASE那么它就可以工作了。但是，如果我使用最新版本，它会失败，为什么？最新版本2.0.1.RELEASE。

我正在使用来自http://www.javainuse.com/spring/boot-admin的代码，但使用了最新的依赖项。

我也遇到了这个问题，从 Spring Boot 1.5.15 升级到 2.1.4

原来我忘记将 Spring Cloud 版本更新为与 Spring Boot 2 兼容的版本。更新版本以Greenwich.RELEASE解决问题。

您需要使用新版本 2.0.0.SNAPSHOT 仅此版本支持 Spring Boot 2.0+，只需使用存储库：

<repository>
<id>sonatype-nexus-snapshots</id>
<name>Sonatype Nexus Snapshots</name>
<url>https://oss.sonatype.org/content/repositories/snapshots/</url>
<snapshots>
    <enabled>true</enabled>
</snapshots>
<releases>
    <enabled>false</enabled>
</releases>

然后对于服务器应用程序导入：

<dependency>
  <groupId>de.codecentric</groupId>
  <artifactId>spring-boot-admin-starter-server</artifactId>
  <version>2.0.0-SNAPSHOT</version>
</dependency>

对于客户：

<dependency>
  <groupId>de.codecentric</groupId>
  <artifactId>spring-boot-admin-starter-client</artifactId>
  <version>2.0.0-SNAPSHOT</version>
</dependency>
