我花了3个多小时的时间来解决这个问题，但不幸的是我无法修复它。任何人都可以帮我吗？
这是我在使用solrj运行deletebyQuery时获得的异常，同时添加到solr工作正常。 注意：deletebyQuery无效但添加正常。

这是我的SolrServerHolder代码。
public class SolrServerHolder {
private static SolrClient concurrentSolrServer = null;
private static HttpSolrClient solrServer = null;
@SuppressWarnings("deprecation")
private static HttpSolrServer httpServer = null;
private static DefaultHttpClient client = null;
private static synchronized void initHttpClient() {
try {
PoolingClientConnectionManager connManager = new PoolingClientConnectionManager();
connManager.setDefaultMaxPerRoute(20); // Allow upto 20 connections for solr server
connManager.setMaxTotal(1000);
client = new DefaultHttpClient(connManager);
} catch (Error e) {
e.getMessage();
}
}
private static synchronized void initConcurrentSolrServer() throws Exception {
if(client == null)
initHttpClient();
UsernamePasswordCredentials defaultcreds = new UsernamePasswordCredentials("XXXX", "YYYY");
client.getCredentialsProvider().setCredentials(
new AuthScope("localhost",
"8090", AuthScope.ANY_REALM),defaultcreds);
concurrentSolrServer = new ConcurrentUpdateSolrClient("http://localhost:8090/solr/abc", client, 5000, 2);
}
public static SolrClient getConcurrentSolrServer() throws Exception {
if(concurrentSolrServer == null)
initConcurrentSolrServer();
return concurrentSolrServer;
}
}
以下是我的代码，它将尝试通过查询删除数据并抛出异常：
SolrClient server =SolrServerHolder.getConcurrentSolrServer();
server.deleteByQuery("id:65657575", 12000);
server.commit();
如果我试图将文档添加到solr，它的工作完全正常
SolrInputDocument docs = getDocs();
SolrClient server =SolrServerHolder.getConcurrentSolrServer();
server.add(abc);
server.commit();
我已经审问了类似的问题和解决方案，但它对我没有帮助。
