使用pinyin4j将汉字转换成拼音

Maven引入依赖:

<dependency>
  <groupId>com.belerweb</groupId>
  <artifactId>pinyin4j</artifactId>
  <version>2.5.0</version>
</dependency>

自己封装了一个工具类:

package com.ylmob.yunpay.util.pinyin;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

import net.sourceforge.pinyin4j.PinyinHelper;
import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;
import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;
import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
 * @author DJM
 */
public class HanyuPinyinUtil {
    
    Logger logger = LoggerFactory.getLogger(HanyuPinyinUtil.class);
    
    private HanyuPinyinUtil(){
    }
    
    public static HanyuPinyinUtil getInstance(){
        return new HanyuPinyinUtil();
    }
    
    public String toPinyin(String chineseCharacter){
        String pinyin = "";
        for(Character chara: chineseCharacter.toCharArray()){
            logger.info("The character is {}.", chara);
            Pattern pt = Pattern.compile("[\\u4e00-\\u9fa5]+");
            Matcher mt = pt.matcher(chara.toString());
            if(mt.matches()){
                logger.info("The character {} is match.", chara);
                HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
                format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
                String[] hyArr = null;
                try {
                    hyArr = PinyinHelper.toHanyuPinyinStringArray(chara, format);
                } catch (BadHanyuPinyinOutputFormatCombination e) {
                    e.printStackTrace();
                }
                pinyin = pinyin.concat(hyArr[0]);
            }else{
                //过滤空白字符
                Pattern blankPt = Pattern.compile("\\s+"); 
                Matcher blankMt = blankPt.matcher(chara.toString());
                if(!blankMt.matches()){
                    pinyin = pinyin.concat(chara.toString());
                }
            }
        }
        return pinyin;
    }
    
}
