我有一个 solr 索引，我正在使用 mysql DB 进行 DIH。

当我运行该delta-import命令时，正在收集自上次完全导入以来在 DB 中插入的 4 行，但索引没有更新！

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

这是 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>

但是索引仍然没有更新......我该如何解决这个问题？

这是核心的 conf 文件：
https ://github.com/MuhammadHewedy/db_cores/tree/master/db/conf https://github.com/MuhammadHewedy/db_cores/blob/master/db/conf/db-data -config.xml https://github.com/MuhammadHewedy/db_cores/blob/master/db/conf/schema.xml https://github.com/MuhammadHewedy/db_cores/blob/master/db/conf/solrconfig.xml
谢谢。

尝试这个：

转到您的 /blob/master/db/conf/dataimport.properties 添加以下内容：

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

检查http://wiki.apache.org/solr/DataImportHandler这个文档。

重要的是commit=true。如果您通过运行进行手动提交，请检查是否看到新数据

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