Cloud Foundry 支持
Spring Boot 的 actuator 模块包括额外的支持,当您部署到兼容的 Cloud Foundry 实例时,将激活这些支持。
该路径提供了到所有 @Endpoint
bean 的替代安全路由。/cloudfoundryapplication
扩展支持允许使用 Spring Boot 执行器信息来增强 Cloud Foundry 管理 UI(例如可用于查看已部署应用程序的 Web 应用程序)。 例如,应用程序状态页面可以包含完整的运行状况信息,而不是典型的“正在运行”或“已停止”状态。
普通用户无法直接访问该路径。
要使用终端节点,您必须在请求中传递有效的 UAA 令牌。/cloudfoundryapplication |
禁用扩展的 Cloud Foundry Actuator 支持
如果要完全禁用终端节点,可以将以下设置添加到您的文件中:/cloudfoundryapplication
application.properties
-
Properties
-
YAML
management.cloudfoundry.enabled=false
management:
cloudfoundry:
enabled: false
Cloud Foundry 自签名证书
默认情况下,端点的安全验证会对各种 Cloud Foundry 服务进行 SSL 调用。
如果您的 Cloud Foundry UAA 或 Cloud Controller 服务使用自签名证书,则需要设置以下属性:/cloudfoundryapplication
-
Properties
-
YAML
management.cloudfoundry.skip-ssl-validation=true
management:
cloudfoundry:
skip-ssl-validation: true
自定义上下文路径
如果服务器的 context-path 已配置为 以外的任何内容,则 Cloud Foundry 端点在应用程序的根目录中不可用。
例如,如果 中的 Cloud Foundry 端点在 上可用。/
server.servlet.context-path=/app
/app/cloudfoundryapplication/*
如果您希望 Cloud Foundry 端点始终在 上可用,而不管服务器的上下文路径如何,则需要在应用程序中显式配置它。
配置会有所不同,具体取决于所使用的 Web 服务器。
对于 Tomcat,您可以添加以下配置:/cloudfoundryapplication/*
