Solr学习笔记——导入JSON数据
1.导入JSON数据的方式有两种,一种是在web管理界面中导入,另一种是使用curl命令来导入
curl http://localhost:8983/solr/baikeperson/update/json?commit=true --data-binary @/home/XXX/下载/person/test1.json -H 'Content-type:text/json; charset=utf-8'
2.导入的时候注意格式
使用curl可以导入的格式
{ "add": { "overwrite": true, "doc": { "id": 1, "name": "Some book", "author": ["John", "Marry"] } }, "add": { "overwrite": true, "boost": 2.5, "doc": { "id": 2, "name": "Important Book", "author": ["Harry", "Jane"] } }, "add": { "overwrite": true, "doc": { "id": 3, "name": "Some other book", "author": "Marry" } } }
在web界面中可以导入的格式
{"title":"许宝江","url":"7254863","chineseName":"许宝江","sex":"男","occupation":" 滦县农业局局长","nationality":"中国"}
不可以导入的格式
{"title":"鲍志成","url":"2074015","chineseName":"鲍志成","occupation":"医师","nationality":"中国","birthDate":"1901年","deathDate":"1973年","graduatedFrom":"香港大学"} {"title":"许宝江","url":"7254863","chineseName":"许宝江","sex":"男","occupation":" 滦县农业局局长","nationality":"中国"}
格式转换的Scala代码
import java.io.{File, PrintWriter} import scala.io.Source /** * Created by common on 17-5-10. */ object SplitJson { def main(args: Array[String]): Unit = { val inputPath = "/home/common/下载/person/part-r-00000-47c2fce6-87cb-4a33-af2c-309a621b070f.json" val outputPath = "/home/common/下载/person/split.json" val pw = new PrintWriter(new File(outputPath)) val s = Source.fromFile(new File(inputPath)).getLines() pw.append("{\"add\": {\"overwrite\": true,\"doc\":") s.foreach { x => if (s.hasNext) pw.append(s"$x").write("},\"add\": {\"overwrite\": true,\"doc\": \n") else pw.append(s"$x").write("}}\n") } pw.flush pw.close } }
导入成功将会返回,导入之后需要等上一段时间才会生成索引
{"responseHeader":{"status":0,"QTime":86}}
注意有可能还需要在下面的地址中加上
/var/solr/data/baikeperson/conf
<requestHandler name="/update/json" class="solr.JsonUpdateRequestHandler" />
