我正在开发一个网络应用程序。我使用 spring mvc 框架、cassandra 和 solr。我使用独立的 solr，而不是 solr 云。我使用 solr 作为全文检索工具。我面临一个奇怪的问题，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" />
<!-- user activity -->
<field name="userOperate" type="string" indexed="true" stored="true" multiValued="false"/>
<!--user reputation-->
<field name="reputation" type="int" indexed="true" stored="true"/>
<field name="dayTime" type="string" indexed="true" stored="true"/>
<field name="reason" type="string" indexed="true" stored="true" multiValued="false" />
<!--user tags-->
<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>
然后我给你看 solrconfig.xml
<?xml version="1.0" encoding="UTF-8" ?>

当我从 solr 查询数据时，我一般使用 solrj 库来实现查询。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);
以下代码是查询时的错误信息：

从信息中，我只知道我的控制器、服务和 dao 工作正常。很奇怪，大部分时间都能正常工作，但是刷新JSP页面20次之内一定会报错，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，还出现了许多类似的错误，这次不是名为 userId 的字段，而是名为 dbTable 的字段。
