当我从solr查询时，它发生了一个常见的exception，告诉我未定义的字段userId
我正在开发一个Web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 cloud。 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 。
id userId
然后我向您展示solrconfig.xml
LUCENE_40 ${solr.core0.data.dir:} ${solr.core0.data.dir:} true solrpingquery all solr
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);
以下代码是查询期间的错误信息：

从信息中，我只知道我的控制器，服务和dao正常工作。 很奇怪它在大多数时间里都能正常工作，但是我刷新JSP页面时必须在20次内发生错误，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。
另外，发生了许多相同的错误，如下所示，这次不是名为userId的字段，而是名为dbTable的字段。

有人遇到过同样的问题吗？
正如我所见，您在代码中更改了baseUrl。 正如您在评论中所说，您在同一页面查询多个核心，并且所有核心都使用相同的HttpSolrServer 。 因此，您的解决方案似乎缺乏同步，并且可能有两个请求同时运行，一个请求查询另一个请求的“核心”。
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HttpSolrServer ，而是为查询设置其他参数，这将用作HttpSolrServer附加路径。 您需要在创建时为HttpSolrServer设置一次HttpSolrServer ：
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核心分别使用HttpSolrServer ：
Map servers = new HashMap(); servers.put(coreName1, new HttpSolrServer(baseUrl + "/" + coreName1)); ...
导致的代码更改：
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);
