solr(3)整合paoding

1.下载paoding-analysis-2.0.4-beta.zip

http://code.google.com/p/paoding/downloads/list

2.解压压缩包至paoding-analysis-2.0.4-beta

3.设置paoding的home环境变量：

l把paoding-analysis-2.0.4-beta中的dic文件夹考到solr的home文件夹中

l进入paoding-analysis-2.0.4-beta找到paoding-analysis.jar，将其考到tomcat/webapps/solr/solr/WEB-INF/lib下

l解压paoding-analysis.jar，找到文件paoding-dic-home.properties，更改属性如下：

paoding.dic.home=D:/solr/solr/dic（D:/solr/solr为solr的home目录）

l重新编译打包成paoding-analysis.jar

4.封装paoding

package org.paoding;

import java.io.Reader;

import java.util.Map;

import net.paoding.analysis.analyzer.PaodingTokenizer;

import net.paoding.analysis.analyzer.TokenCollector;

import net.paoding.analysis.analyzer.impl.MaxWordLengthTokenCollector;

import net.paoding.analysis.analyzer.impl.MostWordsTokenCollector;

import net.paoding.analysis.knife.PaodingMaker;

import org.apache.lucene.analysis.TokenStream;

import org.apache.solr.analysis.BaseTokenizerFactory;

/**

*中文切词 对庖丁切词的封装

*/

publicclass ChineseTokenizerFactory extends BaseTokenizerFactory {

/**

*最多切分 默认模式

*/

publicstatic final StringMOST_WORDS_MODE = "most-words";

/**

*按最大切分

*/

publicstatic final StringMAX_WORD_LENGTH_MODE = "max-word-length";

private Stringmode = null;

publicvoid setMode(String mode) {

if (mode==null||MOST_WORDS_MODE.equalsIgnoreCase(mode)

||"default".equalsIgnoreCase(mode)) {

this.mode=MOST_WORDS_MODE;

}else if (MAX_WORD_LENGTH_MODE.equalsIgnoreCase(mode)) {

this.mode=MAX_WORD_LENGTH_MODE;

}

else {

thrownew IllegalArgumentException("不合法的分析器Mode参数设置:" + mode);

}

}

@Override

publicvoid init(Map args) {

super.init(args);

setMode( (String) args.get("mode"));

}

public TokenStream create(Reader input) {

returnnew PaodingTokenizer(input, PaodingMaker.make(),

createTokenCollector());

}

private TokenCollector createTokenCollector() {

if(MOST_WORDS_MODE.equals(mode))

returnnew MostWordsTokenCollector();

if(MAX_WORD_LENGTH_MODE.equals(mode))

returnnew MaxWordLengthTokenCollector();

thrownew Error("never happened");

}

}

注：其中需要的包为solr.war中的lib库和庖丁文件包中的paoding-analysis.jar

将以上代码打包为paoding.jar（附件中可下载）,考到tomcat/webapps/solr/solr/WEB-INF/lib下。

5.找到solr的home目录下的conf（即D:\solr\solr\conf）中的schema.xml,做如下修改：

<fieldTypename="text" class="solr.TextField" positionIncrementGap="100">

<analyzertype="index">

<!--<tokenizer class="solr.WhitespaceTokenizerFactory"/>-->

<tokenizerclass="org.paoding.ChineseTokenizerFactory"mode="most-words"/>

··· ···

</analyzer>

<analyzertype="query">

<!--<tokenizer class="solr.WhitespaceTokenizerFactory"/>-->

<tokenizerclass="org.paoding.ChineseTokenizerFactory"mode="most-words"/>

··· ···

</analyzer>

</fieldType>

其中<!-- -->里面的为原来默认的内容

6.重启tomcat即可。进行测试http://localhost:8888/solr/admin/analysis.jsp
