。在这里，Solr的列配置就跟你使用createPut生成的Put搞成一样的列名就行了，当然也可以使用动态列的形式。|
private static void sendConcurrentUpdateSolrServer(final String url,
final int count) throws SolrServerException, IOException {
SolrServer solrServer = new ConcurrentUpdateSolrServer(url, 10000, 20);
for (int i = 0; i < count; i++) {
solrServer.add(getInputDoc(PutCreater.createPut(columnFamily)));
}
