我正在开发spring-cloud-boot-admin示例。在这个例子中，我什么也没做，但是项目仍然不能运行。如果我将spring-boot-starter-parent设置为1.5.4.RELEASE，那么它可以工作。但是如果我使用的是最新版本，为什么会失败呢？最新版本的2.0.1.RELEASE。
我使用的是中的代码，但使用的是最新的依赖项。

我也遇到了这个问题，从Spring Boot 1.5.15升级到2.1.4
原来我忘了把Spring Cloud版本更新到与Spring Boot2兼容的版本，把版本更新到Greenwich.RELEASE就解决了这个问题。

您需要使用新版本2.0.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>对于客户端：
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-client</artifactId>
<version>2.0.0-SNAPSHOT</version>
