Java 获取汉字的拼音或汉字首字母 - 果核剥壳

项目中有需要将输入的汉字转化为拼音和提取每个汉字首字母的功能，记录分享一下

1、引入pinyin4j的maven依赖

<dependency>
<groupId>com.belerweb</groupId>
<artifactId>pinyin4j</artifactId>
<version>2.5.1</version>
</dependency>

2、编写一个拼音处理的工具类

package com.example.mydemo.utils;

import net.sourceforge.pinyin4j.PinyinHelper;
import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;
import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;
import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;
import net.sourceforge.pinyin4j.format.HanyuPinyinVCharType;
import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;
/**
* 拼音工具类
*/
public class PinYinUtil {

/**
* 获取汉字串拼音，英文字符不变
* @param chinese 汉字串
* @return 汉语拼音
*/
public static String getFullSpell(String chinese) {
StringBuffer pybf = new StringBuffer();
char[] arr = chinese.toCharArray();
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
for (int i = 0; i < arr.length; i++) {
if (arr[i] > 128) {
try {
pybf.append(PinyinHelper.toHanyuPinyinStringArray(arr[i], defaultFormat)[0]);
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
} else {
pybf.append(arr[i]);
}
}
return pybf.toString();
}

/**
* 获取汉字串拼音首字母，英文字符不变
* @param chinese 汉字串
* @return 汉语拼音首字母
*/
public static String getFirstSpell(String chinese) {
StringBuffer pybf = new StringBuffer();
char[] arr = chinese.toCharArray();
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
for (int i = 0; i < arr.length; i++) {
if (arr[i] > 128) {
try {
String[] temp = PinyinHelper.toHanyuPinyinStringArray(arr[i], defaultFormat);
if (temp != null) {
pybf.append(temp[0].charAt(0));
}
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
} else {
pybf.append(arr[i]);
}
}
return pybf.toString().replaceAll("\\W", "").trim();
}

public static void main(String[] args) {
System.out.println(getFullSpell("吃饭了吗"));
System.out.println(getFirstSpell("吃饭了吗"));
}
}

运行结果
