Description

The validator endpoint allows already to specify custom resource resolvers, via the parameter resourceResolver. However, there is a use case where this functionality is not sufficient. If you have a dynamically created validator endpoint, like

<camel:recipientList>
<camel:simple>validator:${header.XSD_FILE}?resourceResolver=#resourceResolver</camel:simple>
</camel:recipientList>

where the resource URI of the XSD document is also dynamic (in the example via the header XSD_FILE) and if your resource resolver depends on the resource URI of the XSD document, then the current implementation gives you no solution for this problem. You cannot hand-over the dynamic resource URI to the custom resource resolver.

Therefore we introduce the new parameter resourceResolverFactory where you can specify a factory which implements the method

LSResourceResolver createResourceResolver(CamelContext camelContext, String rootResourceUri);

This method is called when the endpoint is created and gives you access to the endpoint resource URI (parameter rootResourceUri).

Remark: resource resolvers need to have the root resource URI in the case of relative URIs.
