我想在Solr中的DataImporthandler中使用多个数据源,并在查询父实体中的数据库后传递子实体中的URL值.这是我的rss-data-config文件:

<dataConfig>
    <dataSource type="JdbcDataSource" name="ds-db" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/HCDACoreDB" 
                            user="root" password="CDA@318"/>
    <dataSource type="URLDataSource" name="ds-url"/>
    <document>
        <entity name="feeds" query="select f.feedurl, f.feedsource, c.categoryname from feeds f, category c where f.feedcategory = c.categoryid">

        <field column="feedurl" name="url" dataSource="ds-db"/>
        <field column="categoryname" name="category" dataSource="ds-db"/>

        <field column="feedsource" name="source" dataSource="ds-db"/>

        <entity name="rss"
                transformer="HTMLStripTransformer" 
                forEach="/RDF/channel | /RDF/item" 
                processor="XPathEntityProcessor" 
                url="${dataimporter.functions.encodeUrl(feeds.feedurl)}" > 

            <field column="source-link" dataSource="ds-url" xpath="/rss/channel/link" commonField="true" />
            <field column="Source-desc" dataSource="ds-url" xpath="/rss/channel/description" commonField="true" />
            <field column="title" dataSource="ds-url" xpath="/rss/channel/item/title" />
            <field column="link" dataSource="ds-url" xpath="/rss/channel/item/link" />
            <field column="description" dataSource="ds-url" xpath="/rss/channel/item/description" stripHTML="true"/>
            <field column="pubDate" dataSource="ds-url" xpath="/rss/channel/item/pubDate" …
