使用solrj遇到奇怪问题?报错

@RequestMapping(value = "/solr", method = RequestMethod.GET)
	public void getSolr() throws SolrServerException, IOException {

		String urlString = "http://192.168.10.129:8983/solr/mycore";
		SolrClient client = new HttpSolrClient.Builder(urlString).build();
		SolrInputDocument doc = new SolrInputDocument();
		doc.addField("id", "c");
		client.add(doc);
		client.commit();
	}

就是创建个索引，然后就报错啦

doc是被add进去了，但是commit失败了。

如果把add doc和commit分成2次请求就没问题了，如下:

@RequestMapping(value = "/solr", method = RequestMethod.GET)
	public void getSolr() throws SolrServerException, IOException {

		String urlString = "http://192.168.10.129:8983/solr/mycore";
		SolrClient client = new HttpSolrClient.Builder(urlString).build();
		SolrInputDocument doc = new SolrInputDocument();
		doc.addField("id", "c");
		client.add(doc);
	}
	@RequestMapping(value = "/solr2", method = RequestMethod.GET)
	public void getSolr2() throws SolrServerException, IOException {

		String urlString = "http://192.168.10.129:8983/solr/mycore";
		SolrClient client = new HttpSolrClient.Builder(urlString).build();
		client.commit();
	}

执行query操作也没有问题。

solr：6.60

jdk：1.8
