使用solrj和EasyNet.Solr进行原子更新
Solr 4.0(http://lucene.apache.org/solr/)已经发布了有一段时间了,其中Solr 4.0中有一个不错的特性:Atom Update,也就是原子更新。有了原子更新这个东东,我们就可以只更新某个字段。下面的代码演示了如何用solrj和EasyNet.Solr(http://easynet.codeplex.com)进行原子更新。
使用solrj进行原子更新:
1 import org.apache.solr.client.solrj.impl.ConcurrentUpdateSolrServer 2 import org.apache.solr.common.SolrInputDocument 3 4 object SolrTest extends App { 5 val url = "http://localhost:8080/example/collection1" 6 val server = new ConcurrentUpdateSolrServer(url, 100, 3) 7 8 //init 9 //atomSet 10 atomAdd 11 12 def init = { 13 val doc = new SolrInputDocument() 14 doc.addField("id", "F8V7067-APL-KIT") 15 doc.addField("name", "Belkin Mobile Power Cord for iPod w/ Dock") 16 doc.addField("features", "car power adapter") 17 doc.addField("features", "white") 18 19 server.add(doc) 20 server.commit() 21 server.shutdown() 22 } 23 24 def atomSet = { 25 val doc = new SolrInputDocument() 26 doc.addField("id", "F8V7067-APL-KIT") 27 28 val setOper = new java.util.HashMap[String, String]() 29 setOper.put("set", "iPod & iPod Mini USB 2.0 Cable") 30 31 doc.addField("name", setOper) 32 33 server.add(doc) 34 server.commit() 35 server.shutdown() 36 } 37 38 def atomAdd = { 39 val doc = new SolrInputDocument() 40 doc.addField("id", "F8V7067-APL-KIT") 41 42 val addOper = new java.util.HashMap[String, String]() 43 addOper.put("add", "add a test feature") 44 45 doc.addField("features", addOper) 46 47 server.add(doc) 48 server.commit() 49 server.shutdown() 50 } 51 }
使用EasyNet.Solr进行原子更新:
