当我从solr进行查询时，发生了一个常见的异常，告诉我未定义的字段userId

java solr

我正在开发一个Web应用程序。我使用弹簧mvc框架，cassandra和solr。我使用独立的solr，而不是solr cloud。我使用solr作为全文检索工具。我正面临着一个奇怪的问题，首先是.schema.xml

<schema name="KSP_core" version="1.1">
  <types>
    <fieldType name="uuid" class="solr.UUIDField" indexed="true" />  
    <fieldType name="date" class="solr.TrieDateField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0"/>
    <fieldtype name="string"  class="solr.StrField" sortMissingLast="true" omitNorms="true"/>
    <fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="double" class="solr.TrieDoubleField" precisionStep="0" positionIncrementGap="0"/>
  <fieldType name="text_ik" class="solr.TextField"> 
    <analyzer type="index" isMaxWordLength="true" class="org.wltea.analyzer.lucene.IKAnalyzer"/> 
    <analyzer type="query" isMaxWordLength="true" class="org.wltea.analyzer.lucene.IKAnalyzer"/> 
    </fieldType>
  </types>

 <fields>   
  <!-- general -->
  <field name="id"        type="uuid"    indexed="true"  stored="true"  multiValued="false" required="true"/>
  <field name="dbTable"      type="string"    indexed="true"  stored="true"  multiValued="false" /> 
  <field name="userId"      type="string"    indexed="true"  stored="true"  multiValued="false" /> 
  <field name="originatorId"      type="string"    indexed="true"  stored="true"  multiValued="false" />
  <field name="associatedObjectId"      type="string"    indexed="true"  stored="true"  multiValued="false" /> 
  <field name="createTime"      type="date"      indexed="true"  stored="true"/>
  <field name="status"     type="int"    indexed="true"  stored="true"  multiValued="false" />
  <field name="postType"      type="string"    indexed="true"  stored="true"  multiValued="false" />

  <field name="tagId"      type="string"    indexed="true"  stored="true"  multiValued="false" /> 
  <field name="tagName"      type="string"    indexed="true"  stored="true"  multiValued="false" /> 

  <field name="reputationOnTag" type="int"      indexed="true"  stored="true"/>
  <field name="_version_" type="long" indexed="true" stored="true"/>
 </fields>

  <uniqueKey>id</uniqueKey>
 <!-- field for the QueryParser to use when an explicit fieldname is absent -->
 <defaultSearchField>userId</defaultSearchField>

 <!-- SolrQueryParser configuration: defaultOperator="AND|OR" -->
 <solrQueryParser defaultOperator="OR"/>
</schema>

然后我向你展示solrconfig.xml

当我从solr查询数据时，我使用solrj库来实现一般的查询。喜欢：

   String queryExpression = "*:*";
   String sortField = "createTime";
   String baseUrl = SolrUtil.getSolrBaseURL(solrHttpServer.getBaseURL());
   solrHttpServer.setBaseURL(baseUrl + "/" + coreName);
   SolrQuery query = new SolrQuery();
   query.setQuery(queryExpression);
   query.setSortField(sortField, SolrQuery.ORDER.asc);
   QueryResponse rsp = solrHttpServer.query(query);

以下代码是查询过程中的错误信息：

从信息中，我只知道我的控制器，服务和dao工作正常。非常奇怪的是，它在大多数时间里都能正常工作，但是错误必须在20次之内发生，我刷新了JSP页面，这让我很担心。我可以保证我的solr服务器正常启动。并且索引已加载。我不知道如何找到解决它的方法，因为我不知道问题的根源。

此外，还发生了许多与下面相同的错误，这次不是名为userId的字段，而是名为dbTable的字段。

有没有人遇到同样的问题？


答案 1

正如我所看到的，你在代码中更改了baseUrl。正如您在评论中所说，您在同一页面上查询多个内核，并且所有这些内核都使用相同的.因此，您的解决方案中似乎缺乏同步，并且可能有两个请求同时运行，并且一个请求查询另一个请求的“核心”。HttpSolrServer

当然，您可以同步您的方法。但我认为，在您的情况下，最好不要每次都抽搐，而是为查询设置其他参数，这将用作您的。您需要在创建时设置一次：HttpSolrServerbaseUrlbaseUrlHttpSolrServer

HttpSolrServer solrHttpServer = new HttpSolrServer(baseUrl);

而不是为每个查询更改它，您将设置参数（代码的差异）：

 String queryExpression = "*:*";
 String sortField = "createTime";
-String baseUrl = SolrUtil.getSolrBaseURL(solrHttpServer.getBaseURL());
-solrHttpServer.setBaseURL(baseUrl + "/" + coreName);
 SolrQuery query = new SolrQuery();
+query.set(CommonParams.QT, "/" + coreName + "/select");
 query.setQuery(queryExpression);
 query.setSortField(sortField, SolrQuery.ORDER.asc);
 QueryResponse rsp = solrHttpServer.query(query);

但最好的解决方案是为每个内核单独设置：HttpSolrServer

Map<String, HttpSolrServer> servers = new HashMap<String, HttpSolrServer>();
servers.put(coreName1, new HttpSolrServer(baseUrl + "/" + coreName1));
...

生成的代码更改：

 String queryExpression = "*:*";
 String sortField = "createTime";
-String baseUrl = SolrUtil.getSolrBaseURL(solrHttpServer.getBaseURL());
-solrHttpServer.setBaseURL(baseUrl + "/" + coreName);
 SolrQuery query = new SolrQuery();
 query.setQuery(queryExpression);
 query.setSortField(sortField, SolrQuery.ORDER.asc);
-QueryResponse rsp = solrHttpServer.query(query);
+QueryResponse rsp = servers.get(coreName).query(query);
