Spring Boot’s actuator module includes additional support that is activated when you
deploy to a compatible Cloud Foundry instance. The /cloudfoundryapplication
path
provides an alternative secured route to all @Endpoint
beans.
The extended support lets Cloud Foundry management UIs (such as the web application that you can use to view deployed applications) be augmented with Spring Boot actuator information. For example, an application status page may include full health information instead of the typical “running” or “stopped” status.

If you want to fully disable the /cloudfoundryapplication
endpoints, you can add the
following setting to your application.properties
file:
application.properties.
management.cloudfoundry.enabled=false
By default, the security verification for /cloudfoundryapplication
endpoints makes SSL
calls to various Cloud Foundry services. If your Cloud Foundry UAA or Cloud Controller
services use self-signed certificates, you need to set the following property:
application.properties.
management.cloudfoundry.skip-ssl-validation=true
If the server’s context-path has been configured to anything other then /
, the Cloud Foundry endpoints
will not be available at the root of the application. For example, if server.servlet.context-path=/foo
,
Cloud Foundry endpoints will be available at /foo/cloudfoundryapplication/*
.
If you expect the Cloud Foundry endpoints to always be available at /cloudfoundryapplication/*
, regardless of
the server’s context-path, you will need to explicitly configure that in your application. The configuration will differ
depending on the web server in use. For Tomcat, the following configuration can be added:
@Bean public TomcatServletWebServerFactory servletWebServerFactory() { return new TomcatServletWebServerFactory() { @Override protected void prepareContext(Host host, ServletContextInitializer[] initializers) { super.prepareContext(host, initializers); StandardContext child = new StandardContext(); child.addLifecycleListener(new Tomcat.FixContextListener()); child.setPath("/cloudfoundryapplication"); ServletContainerInitializer initializer = getServletContextInitializer( getContextPath()); child.addServletContainerInitializer(initializer, Collections.emptySet()); child.setCrossContext(true); host.addChild(child); } }; } private ServletContainerInitializer getServletContextInitializer(String contextPath) { return (c, context) -> { Servlet servlet = new GenericServlet() { @Override public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException { ServletContext context = req.getServletContext() .getContext(contextPath); context.getRequestDispatcher("/cloudfoundryapplication").forward(req, res); } }; context.addServlet("cloudfoundry", servlet).addMapping("/*"); }; }
