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>

但出于某种原因它不起作用。

错误消息：

{msg=SolrCore 'db‘由于init失败而不可用: uniqueKey字段(null)无法配置默认值(新建)。trace=org.apache.solr.common.SolrException: SolrCore 'db‘由于init失败而不可用: uniqueKey字段(null)不能配置为默认值(NEW)。模式文件是.\示例-DIH\solr\db\schema.xml at org.apache.solr.core.CoreContainer.getCore(CoreContainer.java:818) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:289) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:197) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1419) at org.eclipse.jetty.servlet.ServletHandler.doHandle(( org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:137) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:557) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:231) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1075) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java：)384)在org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:193) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1009) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:135) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:255) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java：在org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:116) at org.eclipse.jetty.server.Server.handle(Server.java:368) at org.eclipse.jetty.server.AbstractHttpConnection.handleRequest(AbstractHttpConnection.java:489) at org.eclipse.jetty.server.BlockingHttpConnection.handleRequest(BlockingHttpConnection.java:53) at org.eclipse.jetty.server.AbstractHttpConnection.headerComplete(AbstractHttpConnection.java:942) at org。eclipse.jetty.server.AbstractHttpConnection$RequestHandler.headerComplete(AbstractHttpConnection.java:1004) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:640) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:235) at org.eclipse.jetty.server.BlockingHttpConnection.handle(BlockingHttpConnection.java:72) at org.eclipse.jetty.server.bio.SocketConnector$ConnectorEndPoint.run(SocketConnector.java:264) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:608) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:543) at java.lang.Thread.run(未知源)由: org.apache.solr.common.SolrException: uniqueKey字段(null)引起，无法配置默认值(新建)。模式文件是.\示例-DIH\solr\db\schema.xml at org.apache.solr.schema.IndexSchema.readSchema(IndexSchema.java:608) at org.apache.solr.schema.IndexSchema.(IndexSchema.java:166) at org.apache.solr.schema.IndexSchemaFactory.create(IndexSchemaFactory.java:55) at org.apache.solr.schema.IndexSchemaFactory.buildIndexSchema(IndexSchemaFactory.java:69) at org.apache.solr.core.CoreContainer.createFromLocal(CoreContainer( org.apache.solr.core.CoreContainer.create(CoreContainer.java:592) at org.apache.solr.core.CoreContainer$1.call(CoreContainer.java:271) at org.apache.solr.core.CoreContainer$1.call(CoreContainer.java:263) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) java.util.concurrent.FutureTask.run(未知来源)(在java.util.concurrent.FutureTask$Sync.innerRun(Unknown来源)在java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown来源的java.util.concurrent.FutureTask.run(未知源).1由: org.apache.solr.common.SolrException: uniqueKey字段(null)造成的，不能在org.apache.solr.schema.IndexSchema.readSchema(IndexSchema.java:536)配置默认值(新的)。

更新：

在我做了leoh在下面的回答中建议的修改之后，我收到了以下错误消息：

我也忘记提到，在使用dataimporthandler时，我收到了错误消息。

我试图删除以下内容，但是没有任何索引：

    <!-- 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>

对于第二个错误"init：“，您需要在elevate.xml文件中修改uid。提升文件的默认路径是

@ SOLR_HOME\example\example-DIH\solr\solr\conf 

可能您通往该文件的路径可能有所不同。

如果您想知道在elevate.xml文件中的确切位置，那么请附加您的elevate.xml文件。
