HST Core Spring Extension Points

The HST core exposes a number of Spring-managed bean IDs which a Bloomreach Experience Manager project can use or override.

When a project is entitled to use a Spring bean managed by the HST core (retrieving it through HST's ComponentManager or injecting it into a project-specific Spring bean through configuration, such as a constructor argument or by calling a setter on the bean), we declare that bean as API.

When a project is entitled to override a Spring bean managed by the HST core (by defining a project-specific Spring bean with the same ID), we declare that bean as SPI (service provider interface).

Here is a list of Spring beans managed by the HST code and intended for API or SPI usage by projects.

Spring Bean ID Usage
org.hippoecm.hst.platform.HstModelProvider API
customChannelFilters SPI
customChannelManagerEventListeners SPI
hstJmvEnabledUsers (lab) API
javax.jcr.Credentials.default API
javax.jcr.Credentials.default.delegating API
javax.jcr.Credentials.preview API
javax.jcr.Credentials.preview.delegating API
javax.jcr.Credentials.writable API
javax.jcr.Credentials.hstconfigreader API
javax.jcr.Credentials.hstconfigreader.delegating API
javax.jcr.Credentials.binaries API
javax.jcr.Repository API
javax.jcr.Repository.delegating API
javax.jcr.Repository.subjectBased API
org.hippoecm.hst.core.request.ContextCredentialsProvider (lab) SPI
org.hippoecm.hst.security.AuthenticationProvider SPI
org.hippoecm.hst.core.linking.HstLinkProcessor SPI
org.hippoecm.hst.core.linking.HstLinkCreator.binaryLocations SPI
org.hippoecm.hst.core.linking.RewriteContextResolver SPI
customResourceResolvers SPI
customResourceContainers SPI
customJcrObservationEventListenerItems SPI
org.hippoecm.hst.core.container.PageErrorHandler SPI
Usage of other HST core Spring beans is not guaranteed to be stable across releases, and therefore strongly discouraged.
