---------------------------------------------------------------------
I have used this construction to load database configurations, now I got an error.
What's the best way to load configurations for each core in solrconfig.xml?
{\{<xi:include href="file:///var/lib/solr/conf/database.dih.prod.cr.xml" xmlns:xi="http://www.w3.org/2001/XInclude"> }}
{\{<xi:fallback> }}
{{ <}}{\{xi:include href="file:///var/lib/solr/conf/database.dih.dev.cr.xml" /> }}
{{</xi:fallback>}}
{\{ </xi:include>}}
*database.dih.dev.cr.xml*
{{<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="config">data-config.xml</str> <lst name="datasource"> <str name="driver">org.mariadb.jdbc.Driver</str> <str name="url">jdbc:mysql://localhost:3306database_name</str> <str name="user">userName</str> <str name="password">password</str> </lst> </lst> </requestHandler>}}

> It appears that in QueryTemplateManager.java lines 149 and 198 and in DOMUtils.java line 204 XML is parsed without disabling external entity references (XXE). This is described in [http://cwe.mitre.org/data/definitions/611.html] and possible mitigations are listed here: [https://www.owasp.org/index.php/XML_External_Entity_(XXE)_Prevention_Cheat_Sheet]
> All recent versions of lucene are affected.
