最近在工作開發(fā)中有一個(gè)需求晦攒，需要將用戶的中文名轉(zhuǎn)換為拼音逛犹。經(jīng)過(guò)一番搜索之后端辱，我找到了實(shí)現(xiàn)方法梁剔。
首先引入第三方j(luò)ar包pinyin4j-2.5.0.jar，對(duì)應(yīng)的maven依賴如下：

<dependency>
    <groupId>com.github.open-android</groupId>
    <artifactId>pinyin4j</artifactId>
    <version>2.5.0</version>
</dependency>

具體實(shí)現(xiàn)代碼如下：

package com.wunian.pinyin;

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

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

public class HanZi2PinYinDemo {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner scanner =new Scanner(System.in);
        System.out.println("請(qǐng)輸入漢字：");
        String hanzi = scanner.next();
        System.out.println("轉(zhuǎn)換成拼音：");
        System.out.println(convertHanzi2Pinyin(hanzi, true));
    }


    public static String convertHanzi2Pinyin(String hanzi, boolean full) {
        /***

        if (hanzi == null || "".equals(hanzi.trim())) {
            return "";

        String pinyin = "";
        for (int i = 0; i < hanzi.length(); i++) {
            char unit = hanzi.charAt(i);
            if (match(String.valueOf(unit), regExp))// 是漢字舞蔽，則轉(zhuǎn)拼音
            {
                pinyin = convertSingleHanzi2Pinyin(unit);
                if (full) {

            }
        }
        return sb.toString();
    }
