Issue Type: New Feature Assignee: Unassigned Components: Spring Created: 23/Feb/22 11:31 AM Priority: Trivial Reporter: Henri Mikkonen ( https://shibboleth.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A1614c4a5-c89e-4edc-9421-990bd6ea85fd )

The base class for Spring MVC HandlerMapping implementations ( org.springframework.web.servlet.handler.AbstractHandlerMapping ) provides functionality to handle CORS requests. They can't currently be used as the beans are initialised in the *mvc-beans.xml* file residing in the idp-conf-impl JAR. For instance:

   <bean class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping" p:order="0"
           p:flowRegistry-ref="flowRegistry">
       <property name="flowUrlHandler">
           <bean class="net.shibboleth.idp.profile.support.PathInfoSupportingFlowUrlHandler"
               p:supportedFlows="#{getObject('shibboleth.RESTFlows') ?: getObject('shibboleth.DefaultRESTFlows')}" />
       </property>
   </bean>

The bean could be initialised with a configurable corsConfigurationSource -property in order to activate the CORS handling for the desired endpoints.
