java - 使用solrj创建索引时遇到的奇怪问题？

问题描述

@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

iteye上一个类似的情况：

问题解答

临时解决方案，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，这个是部分译文http://www.cnblogs.com/llz502...

为什么这样就可以了呢？还是好奇怪
