solr使用.docx

1、solr使用Solr 1.4.1配置和SolrJ的用法一、 Solr基本安装和配置 imageLens samples a href=http:/www.script- to original article page 1， 使用slorj的清除原有的索引.或者手动删除。2， 编写代码，将lucene建立的索引（1G左右,874400条记录），按照比例通过solrj分发到三台solr（shard）服务器上，代码如下:public class IndexCreate private static CommonsHttpSolrServer server; public CommonsHttpSo

2、lrServer getServer(String hostUrl) CommonsHttpSolrServer server = null; try server = new CommonsHttpSolrServer(hostUrl); server.setConnectionTimeout(100); server.setDefaultMaxConnectionsPerHost(100); server.setMaxTotalConnections(100); catch (IOException e) System.out.println(请检查tomcat服务器或端口是否开启!);

3、return server; SuppressWarnings(deprecation) public void readerHostCreate(String hosts) throws CorruptIndexException, IOException IndexReader reader = IndexReader.open(c:index); System.out.println(总记录数: +reader.numDocs(); int hostNum = hosts.length; int lengh = reader.numDocs()/hostNum; /根据主机数平分索引长度

4、 int j = reader.numDocs()%hostNum; /取余 for(int i = 0;ihosts.length;i+) long startTime = new Date().getTime(); String url = hostsi.substring(hostsi.indexOf(/)+2,hostsi.lastIndexOf(/); System.out.println(第+(i+1)+次，在主机:+url+ 上创建索引,创建时间+new Date(); if(i=(hosts.length-1) hostlist(reader,lengh*i,lengh*(i+

5、1)+j,hostsi); else hostlist(reader,lengh*i,lengh*(i+1),hostsi); System.out.println(结束时间+new Date(); long endTime = new Date().getTime(); long ms = (endTime-startTime)%60000-(endTime-startTime)%60000)/1000)*1000; System.out.println(本次索引创建完毕，一共用了+(endTime-startTime)/60000+分 + +(endTime-startTime)%6000

6、0)/1000+秒+ms+毫秒); System.out.println(*); reader.close(); public void createIndex(List beans,String hostUrl,CommonsHttpSolrServer server) try server.addBeans(beans); mit(); catch (SolrServerException e) e.printStackTrace(); catch (IOException e) e.printStackTrace(); public static void main(String arg

7、s) throws CorruptIndexException, IOException IndexCreate as = new IndexCreate(); String hosts = new String http:/192.168.169.121:9888/solr,http:/192.168.169.121:9088/solr,http:/192.168.169.48:9888/solr; long startTime = new Date().getTime(); as.readerHostCreate(hosts); long endTime = new Date().getT

8、ime(); System.out.println(-); long ms = (endTime-startTime)%60000-(endTime-startTime)%60000)/1000)*1000; System.out.println(全部索引创建完毕，一共用了+(endTime-startTime)/60000+分 + +(endTime-startTime)%60000)/1000+秒+ms+毫秒); JavaBean类BookIndex.java代码如下:说明变量名与sechma.xml中的配置要相同.注意：不能使用score这个变量或者字段，与slor配置冲突，报excep

9、tion。import org.apache.solr.client.solrj.beans.Field;public class BookIndex Field private String zjid ; Field private String title; Field private String ssid; Field private String dxid; Field private String bookname; Field private String author; Field private String publisher; Field private String p

10、ubdate; Field private String year; Field private String fenlei; Field private String score1; Field private String isbn; Field private String fenleiurl; Field private String mulu; Field private String isp; Field private String iep; public getters();/get方法 public setters();/set方法3， 同时开启四台服务器，运行上面代码:4，

11、 打开IE查询打开:http:/localhost/solr打开:http:/localhost:9888/solr打开http:/localhost:9008/solr打开http:/192.168.168.48:9888/solr四、Solr的Multicore(分片)配置bodybackground:#eee;margin:0;padding:0.examplebackground:#FFF;width:800px;border:1px #000 solid;margin:20px auto;padding:15px;-moz-border-radius: 3px;-webkit-bor

12、der-radius: 3px.example img margin:22px 六、一个简单的web引用: 首先说明的是索引来源，是根据已有的lucene索引上开发的，又因为lucene的索引直接用solrJ应用效果不好，会出现很多问题，找不到类似的解决办法，比如全字段查询，和高亮分组等，和多级索引目录。但用solrJ创建的索引不存在类似的问题. 大致的思路是，读取已有的lucene索引 ，再用solrJ创建索引并分发到多台机器上，最后再做开发. 第一步：读取lucene的多级索引目录，用solrJ创建和分发索引;需注意的是：要加大虚拟机的内存，因为采用的map做为缓存，理论上虚拟机的内存大，

13、map的存储的索引文档数也就多.主要是针对内存溢出. 代码 ：package org.readerIndex;import org.apache.solr.client.solrj.beans.Field;public class BookIndex2 Field private String zjid; Field private String zhangjie; Field private String ssid; Field private String qwpos; Field private String publishDate; Field private String mulu;

14、 Field private String fenleiurl; Field private String fenlei; Field private String dxid; Field private String author; Field private String address; Field private String bookname; public String getZjid() return zjid; package org.readerIndex;import java.io.File;import java.io.IOException;import java.t

15、ext.SimpleDateFormat;import java.util.ArrayList;import java.util.Date;import java.util.List;import org.apache.lucene.document.Document;import org.apache.lucene.index.CorruptIndexException;import org.apache.lucene.index.IndexReader;import org.apache.lucene.store.LockObtainFailedException;import org.a

16、pache.solr.client.solrj.SolrServerException;import org.apache.solr.client.solrj.impl.CommonsHttpSolrServer;public class ReaderIndex public CommonsHttpSolrServer getServer(String hostUrl) CommonsHttpSolrServer server = null; try server = new CommonsHttpSolrServer(hostUrl); server.setConnectionTimeout

17、(100); server.setDefaultMaxConnectionsPerHost(100); server.setMaxTotalConnections(100); catch (IOException e) System.out.println(请检查tomcat服务器或端口是否开启!); return server; public void indexDocuements(String path,String hostUrls) throws CorruptIndexException, LockObtainFailedException, IOException File pa

18、reFile = new File(path); List list = new ArrayList(); getFile(pareFile,list); /递归方法得到路径保存到list中 System.out.println(*程序一共递归到+list.size()+个索引目录*); int arevageSize = list.size()/hostUrls.length;/ 根据主机数平分目录 int remainSize = list.size()%hostUrls.length;/取余 SimpleDateFormat sdf = new SimpleDateFormat(yyyy

19、-MM-dd HH:mm:ss); for(int i=0;ihostUrls.length;i+) Date startDate = new Date(); String url = hostUrlsi.substring(hostUrlsi.indexOf(/)+2,hostUrlsi.lastIndexOf(/); System.out.println(第+(i+1)+次，在主机:+url+ 上创建索引,创建时间 +sdf.format(startDate); if(i=(hostUrls.length-1) list(list,arevageSize*i,arevageSize*(i+

20、1)+remainSize,hostUrlsi); /* */(function ($) $.fn.imageLens = function (options) var defaults = lensSize: 100, borderSize: 4, borderColor: #888 ; var options = $.extend(defaults, options); var lensStyle = background-position: 0px 0px;width: + String(options.lensSize) + px;height: + String(options.le
