solr - 数据导入处理程序中 SolR 的 Tika 处理器未从 DB 处理器获取文件名

Question

我有一个 DIH 配置，我想通过将文件名从 db 传递给 Tika 来组合来自 DB 和 Tika 的数据。问题是 Tika 中的文件名是空的。日志说：

ERROR (Thread-16) [   ] o.a.s.h.d.DataImporter Full Import failed:java.lang.RuntimeException: java.lang.RuntimeException: org.apache.solr.handler.dataimport.DataImportHandlerException: java.lang.RuntimeException: java.io.FileNotFoundException: Could not find file:  (resolved to: C:\Users\jimbo\Desktop\solr-8.9.0\server\.

我的配置xml文件是这样的：

<dataConfig>
    <dataSource name="ds-db" driver="org.mariadb.jdbc.Driver" url="jdbc:mysql://localhost:3306/eepyakm?user=root" user="root" password="wpadmin"/>
    <dataSource name="ds-file" type="BinFileDataSource"/>
    <document>
        <entity name="supplier" query="select * from suppliers_tmp_view" dataSource="ds-db" 
                deltaQuery="select id from suppliers_tmp_view where last_modified > '${dataimporter.last_index_time}'"
                deltaImportQuery="select * from suppliers_tmp_view where id='${dataimporter.delta.id}'">
             
            <entity name="attachment" dataSource="ds-db" 
                    query="select * from suppliers_tmp_files_view where supplier_tmp_id='${supplier.id}'"
                    deltaQuery="select id,supplier_tmp_id from suppliers_tmp_files_view where last_modified > '${dataimporter.last_index_time}'"
                    parentDeltaQuery="select id from suppliers_tmp_view where id='${attachment.supplier_tmp_id}'">
            
                <field name="path" column="path"/>
                
                <entity name="file" processor="TikaEntityProcessor" url="${attachment.path}" format="text" dataSource="ds-file">
                    
                    <field column="text"/>
                </entity>
            </entity>
        </entity>
    </document>
</dataConfig>

我在一篇很老的帖子中发现了一个类似的问题：Solr's TikaEntityProcessor not working
