我在 DIH 中使用 UpdateRequestProcessorChain 并得到数据未提交到索引的问题。我试图调试我的处理器并且它可以工作。完全导入命令的状态是:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">1</int>
</lst>
<lst name="initArgs">
<lst name="defaults">
<str name="update.processor">DataImportChain</str>
<str name="config">data-config.xml</str>
</lst>
</lst>
<str name="command">status</str>
<str name="status">idle</str>
<str name="importResponse"/>
<lst name="statusMessages">
<str name="Total Requests made to DataSource">0</str>
<str name="Total Rows Fetched">7</str>
<str name="Total Documents Skipped">0</str>
<str name="Full Dump Started">2012-04-26 17:47:44</str>
<str name="">Indexing completed. Added/Updated: 6 documents. Deleted 0 documents.</str>
<str name="Committed">2012-04-26 17:47:45</str>
<str name="Optimized">2012-04-26 17:47:45</str>
<str name="Total Documents Processed">6</str>
<str name="Time taken ">0:0:1.174</str>
</lst>
<str name="WARNING">This response format is experimental. It is likely to change in the future.</str>
但是 catalina.out 中没有信息表明调用了提交过程:
26.04.2012 17:47:44 org.apache.solr.handler.dataimport.DataImporter doFullImport

日志中没有任何错误。如果我在没有 UpdateRequestProcessorChain 的情况下使用 DIH,则提交没有问题。有人知道这里可能出了什么问题吗?
这是我的 solrconfig.xml 中的配置:
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="update.processor">DataImportChain</str>
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
<updateRequestProcessorChain name="DataImportChain" >
<processor class="my.package.MyProcessorFactory" />
</updateRequestProcessorChain>
