新建工具类

package com.znzmo.component;

import com.github.pagehelper.util.StringUtil;
import com.google.common.collect.Lists;
import org.springframework.stereotype.Component;
import org.wltea.analyzer.core.IKSegmenter;
import org.wltea.analyzer.core.Lexeme;

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

@Component
public class IKAnalyzerSupport {
    public List<String> iKSegmenterToList(String string){
        List<String> list=new ArrayList<>();
        try{
            if(StringUtil.isEmpty(string)){
                return Lists.newArrayList();
            }
            StringReader sr=new StringReader(string);
            IKSegmenter ik=new IKSegmenter(sr, true);
            Lexeme lex;
            while((lex=ik.next())!=null){
                String lexemeText=lex.getLexemeText();
                if(lexemeText.length()>=2){
                    list.add(lexemeText);
                }
            }
        }catch (Exception e){
            e.printStackTrace();
        }
        return list;
    }
}

添加自定义配置

在resource目录下新建文件

IKAnalyzer.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
    <comment>IKAnalyzer扩展配置</comment>

    <entry key="ext_dict">extend.dic</entry>
    <!--用户扩展停止词字典 -->

</properties>

extend.dic 扩展词库
