ik分词器-简单使用

ik分词器：效果展示

实现步骤
1.引入maven依赖

<!--ik分词-->
        <dependency>
            <groupId>com.janeluo</groupId>
            <artifactId>ikanalyzer</artifactId>
            <version>2012_u6</version>
        </dependency>

2.IK分词工具类

import org.wltea.analyzer.core.IKSegmenter;
import org.wltea.analyzer.core.Lexeme;

import java.io.IOException;
import java.io.StringReader;
import java.util.ArrayList;
import java.util.List;

/**
 * @PackageName: com.hrt.zxxc.sxy
 * @ClassName: IKAnalyzerUtil
 * @Description: TODO ik分词器
 * @Author: 
 * @Date: 2019/11/11 8:50
 * @Versoin: 1.0
 **/
public class IKAnalyzerUtil {

    public static List<String> cut(String msg) throws IOException {
        StringReader sr=new StringReader(msg);
        IKSegmenter ik=new IKSegmenter(sr, true);
        Lexeme lex=null;
        List<String> list=new ArrayList<>();
        while((lex=ik.next())!=null){
            list.add(lex.getLexemeText());
        }
        return list;
    }
}

3.调用

 public List<String> getTitleList(String title) throws IOException {
        return IKAnalyzerUtil.cut(title.trim());
}

4.一些配置文件
① IKAnalyzer.cfg.xml ，配置自己的扩展字典

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
    <comment>IK Analyzer 扩展配置</comment>
    <!--用户可以在这里配置自己的扩展字典 -->
    <entry key="ext_dict">local.dic;</entry>
    <!--用户可以在这里配置自己的扩展停止词字典 -->
    <entry key="ext_stopwords">stop.dic;</entry>
</properties>

②local.dic
③stop.dic
