Blueprint Developer Manual / Version 2201
Table Of Contents
Certain renditions can be excluded from publication. To do so the
am-server-component comes with an AssetPublishInterceptor
which reads the metadata property of assets to determine if a given
rendition should be published or not.
The AssetPublishInterceptor bean is added to the Content
Server and to the corresponding command-line tools. The following properties
control the behavior of the interceptor:
assetMetadataPropertyThe
Structproperty which contains the information whether to publish a rendition or not at pathrenditions.<rendition-name>.show. When the Boolean propertyshowistrue, the rendition blob will be published. Otherwise, the blob will not be available on the master server.interceptingSubtypesBoolean flag to control whether also subtypes of
typeshould be intercepted or not.removeDefaultThe default value to control whether a rendition blob should be removed from publication or not. If unset the default is to remove blobs if nothing else is specified in either the metadata struct or in the removal overrides.
removeOverrideOverrides any setting or default for a given rendition. It contains a map from rendition name to removal flag. Thus, if you want the rendition
thumbnailto be published in any case add an entry with keythumbnailand value false.typeThe document type the interceptor applies to. For subtype processing set the flag
interceptingSubtypesaccordingly.
Example 6.10, “Rendition Publication Configuration” shows a possible configuration of
the AssetPublishInterceptor.
<beans ...> <util:map id="removeOverride" key-type="java.lang.String" value-type="java.lang.Boolean"> <entry key="thumbnail" value="false"/> </util:map> <bean id="assetPublishInterceptor" class= "com.coremedia.blueprint.assets.server.AssetPublishInterceptor"> <property name="type" value="AMAsset"/> <property name="interceptingSubtypes" value="true"/> <property name="assetMetadataProperty" value="metadata"/> <property name="removeDefault" value="true"/> <property name="removeOverride" ref="removeOverride"/> </bean> </beans>
