Java 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

我正在开发一个web应用程序。 我使用SpringMVC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">

以下代码是查询过程中的错误信息：

从这些信息中，我只知道我的控制器、服务和dao工作正常。 非常奇怪的是，它在大多数时间都正常工作，但错误必须在我刷新JSP页面的20次内发生，这让我很担心。 我可以保证我的solr服务器正常启动。 和索引已加载。 我不知道如何找到解决办法，因为我不知道问题的根源

此外，还发生了许多类似以下的错误，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？

如我所见，您可以在代码中更改baseUrl。正如您在评论中所说，您在同一页面上查询多个内核，并且所有内核都使用相同的

HttpSolrServer

。因此，您的解决方案中似乎缺少同步，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，最好不要每次都抽动

HttpSolrServer

，而是为查询设置附加参数，该参数将用作

baseUrl

的附加路径。您需要在创建时为

HttpSolrServer

设置一次

baseUrl

：

HttpSolrServer solrHttpServer = new HttpSolrServer(baseUrl);

您将设置参数（代码的差异），而不是为每个查询更改参数：

---

但最好的解决方案是为每个核心分别配备

HttpSolrServer

：

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

---

我编辑了这篇文章。我使用独立的solr。我使用不同的核心。每个核心都有自己的schema.xml您使用的是什么版本的Solr？我可以假设它是4.0，因为您使用的是LUCENE_40编解码器，但最好确定一下。如果可能的话，您能否将4.5 Solr和luceneMatchVersion更新为

4.5

<代码>和每个核心都有自己的模式。xml确保相关核心中确实有该字段（我知道，我知道，但可能您的代码在同一页查询多个核心，您在不同的核心中搜索问题）。是的，我使用的是solr 4.0。您是对的，我在同一页上查询了多个Core。您正在发布客户端stacktrace，可能还发布了solr内部记录的异常。嗨，我像您所说的那样更改了我的SolrbaseadoImpl.java文件。但是我收到了一个新错误：org.apache.solr.common.SolrException:服务器返回的非正常状态：404，消息：未找到。每次我进行查询时都会发生错误。URL是预期的URL。baserl是在solr.properties中定义的。我使用SpringMVC，属性文件加载到applicationContext.xml中，coreName是KSP_core。但是如果我不像您所说的那样更改代码，它可以工作，但是未定义的字段异常仍然很少发生。

HttpSolrServer solrHttpServer = new HttpSolrServer(baseUrl);

 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);

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

 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);
