問題描述

@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();}

就是創(chuàng)建個(gè)索引，然后就報(bào)錯(cuò)啦

doc是被add進(jìn)去了，但是commit失敗了。

如果把a(bǔ)dd doc和commit分成2次請求就沒問題了，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(); }

執(zhí)行query操作也沒有問題。

solr：6.60

jdk：1.8

iteye上一個(gè)類似的情況：

問題解答

臨時(shí)解決方案，使用如下方法提交：

UpdateRequest req = new UpdateRequest();req.setAction(UpdateRequest.ACTION.COMMIT, false, false);req.add(doc);UpdateResponse rsp = req.process(client);

https://wiki.apache.org/solr/...上找到的，這個(gè)是部分譯文http://www.cnblogs.com/llz502...

為什么這樣就可以了呢？還是好奇怪
