Delta-import收集數據，但不更新solr索引

Question

我有一個Solr索引，我正在使用mysql DB進行DIH。

當我運行delta-import命令時，將收集自上次完全導入以來數據庫中插入的4行，但索引不會更新！

841705 [qtp108251962-14] INFO  org.apache.solr.handler.dataimport.DataImporter  – Loading DIH Configuration: db-data-config.xml

841744 [Thread-31] INFO  org.apache.solr.update.processor.LogUpdateProcessor  – [db] webapp=/solr path=/dataimport params={command=delta-import} status=0 QTime=4 {} 0 4

這是db-data-config.xml：

<dataConfig>
    <dataSource driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/sampledb" user="root" password="system" />
    <document>
        <entity name="employees" pk="ID" 
                query="SELECT * FROM employees"
                deltaImportQuery="SELECT * FROM employees WHERE ID='${dataimporter.delta.id}'"
                deltaQuery="SELECT ID from employees WHERE TRANSTIME &gt; '${dataimporter.last_index_time}'">

            <field column="ID" name="id" />
            <field column="NAME" name="name" />
            <field column="CITY" name="city" />
            <field column="SERVICE_ID" name="service_id" />

       </entity>
    </document>
</dataConfig>

但是仍然沒有更新索引...我該如何解決這個問題？

這是核心的conf文件：

謝謝。

嘗試這個：

轉到您的/blob/master/db/conf/dataimport.properties添加以下內容：

#  URL params [mandatory]
#  remainder of URL
params=/select?qt=/dataimport&command=delta-import&clean=false&commit=true

查看http://wiki.apache.org/solr/DataImportHandler此文檔。

重要的是commit = true。 通過運行以下命令來檢查是否看到新數據：

http://localhost:8080/solr/update?commit=true
