SOLR uniqueKey与solr.UUIDField

Question

尝试使用solr.UUIDField生成uniqueKey字段.

<fieldType name="uuid" class="solr.UUIDField" indexed="true" />


<field name="uid" type="uuid" indexed="true" stored="true" default="NEW" />

<uniqueKey>uid</uniqueKey>

但由于某种原因,它不起作用.

错误信息:

更新:

在我做出了答案中leoh建议的更改后,我收到了以下错误消息:

我也忘了提到它在使用dataimporthandler时我收到了错误信息.

我试图删除以下但没有任何索引:

<searchComponent name="elevator" class="org.apache.solr.handler.component.QueryElevationComponent" >
    <!-- pick a fieldType to analyze queries -->
    <str name="queryFieldType">string</str>
    <str name="config-file">elevate.xml</str>
</searchComponent>

要在solr 4.6中配置uuid字段,您可能需要以下配置

<!--schema.xml-->

<fieldType name="uuid" class="solr.UUIDField" indexed="true" />

<field name="id" type="uuid" indexed="true" stored="true" required="true" />

<uniqueKey>id</uniqueKey>

<!--solrconfig.xml-->
<updateRequestProcessorChain name="uuid">
    <processor class="solr.UUIDUpdateProcessorFactory">
      <str name="fieldName">id</str>
    </processor>
    <processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>


 <requestHandler name="/update" class="solr.UpdateRequestHandler">
       <lst name="defaults">
         <str name="update.chain">uuid</str>
       </lst>
</requestHandler>
