102. springboot 整合IK分詞器

參考：https://blog.csdn.net/chengyuqiang/article/details/102792839

 

1.效果：

2.實現過程

2.1導入jar

<dependency>
    <groupId>com.janeluo</groupId>
    <artifactId>ikanalyzer</artifactId>
    <version>2012_u6</version>
</dependency>

 

2.2 編寫配置文件

2.2.1  IKAnalyzer.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
    <comment>IK Analyzer 擴展配置</comment>
    <!--用戶可以在這裏配置自己的擴展字典 -->
    <entry key="ext_dict">local.dic;</entry>
    <!--用戶可以在這裏配置自己的擴展停止詞字典 -->
    <entry key="ext_stopwords">stop.dic;</entry>
</properties>

 

2.2.2  local.dic

 

2.2.3 stop.dic

 

2.3 測試

工具類：

package cn.ma.life.utils;

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;

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;
    }
}

請求：

package cn.ma.life.controller;

import cn.ma.life.utils.IKAnalyzerUtil;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

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

@RestController
public class AnalyzerController {
    /**
     * http://localhost:8081/IkAnalyzer?word=老闆請給我一把油紙傘
     *
     * @param word
     * @return
     */
    @RequestMapping("/IkAnalyzer")
    public String IkAnalyzer(String word) throws IOException {
        StringBuffer sb = new StringBuffer();
        sb.append("分詞後的關鍵字分別是:");
        List<String> list = IKAnalyzerUtil.cut(word);
        for (int i = 0; i < list.size(); i++) {
            String s = list.get(i);
            if (i < list.size() - 1) {
                sb.append(s);
                sb.append(",");
            } else {
                sb.append(s);
            }
        }
        return sb.toString();
    }
