Solr 1.4：没有提交自定义UpdateRequestProcessorFactory

Question

我在DIH中使用UpdateRequestProcessorChain，并得到数据未提交给索引的问题。我试图调试我的处理器，它的工作原理。全进口命令的状态是：

<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> 

但在catalina.out的任何信息的提交过程被称为：

26.04.2012 17:47:44 org.apache.solr.handler.dataimport.DataImporter doFullImport 
INFO: Starting Full Import 
26.04.2012 17:47:44 org.apache.solr.core.SolrCore execute

26.04.2012 17:47:45 org.apache.solr.handler.dataimport.DocBuilder execute 
INFO: Time taken = 0:0:1.174 

有没有任何错误在日志中。如果我使用没有UpdateRequestProcessorChain的DIH，那么提交没有问题。有没有人知道这里有什么可能是错的？

这里是我的solrconfig.xml中配置：

<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> 

Answer 1

你在你的updateRequestProcessorChain遗漏了一些基本的处理器，这就是为什么没有任何反应。试试这个配置：

<updateRequestProcessorChain name="DataImportChain" > 
    <processor class="my.package.MyProcessorFactory" /> 
    <processor class="solr.RunUpdateProcessorFactory" /> 
    <processor class="solr.LogUpdateProcessorFactory" /> 
</updateRequestProcessorChain> 

的RunUpdateProcessorFactory实际上是在其中一个做内链“普通货色”。如果你忘记了它，你正在预处理一些从未编入索引的东西。
