我正在将我的 spring-boot 升级到 1.5.4，并使用执行器进行健康检查。构建成功，但是当我运行应用程序时，出现以下错误：

    <spring-restdocs.version>1.0.0.RELEASE</spring-restdocs.version>

我已经验证并且执行器类是指 1.5.4 版本的 spring boot，我的应用程序中没有任何其他版本的 spring boot。

任何指针都会有所帮助。

【问题讨论】：

请发布您的 Maven 或 Gradle 文件。是否也升级了 spring-cloud-dependencies？
更新了 maven 依赖。我没有升级spring-cloud。我正在使用 spring-cloud-cloudfoundry-connector 及其指向 1.2.4
对于初学者，请停止混合弹簧版本...您正在混合 4.0、4.1 和 4.3 罐子。删除`spring-context-support-version。旁边你有重复的依赖等，所以从清理你的 pom 开始。
看来你是对的。 spring-webmvc (4.0.8) 版本与 sprint-boot 存在一些冲突。我删除了独家版本控制，现在从父级读取 spring 版本，例如4.3.9 解决了这个问题。
@M.Deinum，您能否将您的评论作为答案，以便我标记它。谢谢。

【解决方案1】：

你的依赖是一团糟。

您正在包括启动器中已经存在的其他依赖项。
您至少在混合 Spring 版本 4.0、4.1 和 4.3。

我建议删除它们并使用启动器，而不是所有单独的依赖项。

【讨论】：

上面给出的解决方案看起来不错。除此之外，您还可以排除彼此冲突的 Maven 工件。（来自依赖层次结构）。类似的东西，添加排除。排除>
