Chinese characters to Pinyin

一,pinyin4j 工具包

We need to use Chinese characters to pinyinpinyin4j这个工具jar包,It can handle converting Chinese into Pinyin（汉语拼音,罗马拼音等）

1,常用类介绍

PinyinHelper Provides the main methods of converting Chinese characters to Pinyin

HanyuPinyinOutputFormat Defines how to output Pinyin,

HanyuPinyinCaseType Provides styles for pinyin output

• LOWERCASE:输出小写,
• UPPERCASE:输出大写

HanyuPinyinToneType Settings for output phonetic symbols

• WITH_TONE_MARK:Use phonetic symbols directly（必须设置WITH_U_UNICODE,否则会抛出异常）,
• WITH_TONE_NUMBER：1-4Numbers represent phonetic symbols,
• WITHOUT_TONE：没有音标

HanyuPinyinVCharType special phonetic symbolsü的设置（了解下）

• WITH_V：用v表示ü,
• WITH_U_AND_COLON：用"u:"表示ü,
• WITH_U_UNICODE：直接用ü

二,使用pinyin4j

1,引用jar包

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

2,写一个工具类

The two methods in the utility class can be combined

/** * @description:汉字转拼音工具类 */
public class HanZiToPinYinUtil {
    

    public static void main(String[] args) {
    
        String allPinYin = getAllPinYin("我是中国人00");
        String firstPinYin = getFirstPinYin("我是中国人00");
        String allPinYin2 = getAllPinYin("王宇");
        System.out.println(allPinYin);
        System.out.println(allPinYin2);
        System.out.println(firstPinYin);
    }

    /** * Get the full pinyin of a Chinese character string * @param hanZi '我是中国人00' * @return */
    public static String getAllPinYin(String hanZi){
    
        //This class defines how to output Hanyu Pinyin.
        HanyuPinyinOutputFormat pinyinOutputFormat = new HanyuPinyinOutputFormat();
        pinyinOutputFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);//Output in lowercase,LOWERCASE:输出小写,UPPERCASE:输出大写
        pinyinOutputFormat.setToneType(HanyuPinyinToneType.WITH_TONE_MARK);//Output phonetic settings,WITH_TONE_MARK:Use phonetic symbols directly（必须设置WITH_U_UNICODE,否则会抛出异常）,WITH_TONE_NUMBER：1-4Numbers represent phonetic symbols,WITHOUT_TONE：没有音标
        pinyinOutputFormat.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE);//special phonetic symbolsü的设置,（WITH_V：用v表示ü,WITH_U_AND_COLON：用"u:"表示ü,WITH_U_UNICODE：直接用ü）

        char[] hanziChars = hanZi.trim().toCharArray();//汉字数组,去掉前后多余的空格
        StringBuilder stringBuilder = new StringBuilder();
        try {
    
            for (int i = 0; i < hanziChars.length; i++) {
    
                String hanziString = Character.toString(hanziChars[i]);//Get a single Chinese character,例如‘中’
                if(hanziString.matches("[\\u4e00-\\u9fa5]")){
    //判断是否是汉字
                    String[] pinYinAll = PinyinHelper.toHanyuPinyinStringArray(hanziChars[i],pinyinOutputFormat);//Get all the pronunciations of this Chinese character,For example, Zhong is a polyphonic word,其结果就是['zhōng','zhòng']
                    String oneHanZiPinYin = pinYinAll[0];//Directly take a pinyin as a Chinese character,例如zhōng
                    stringBuilder.append(oneHanZiPinYin);
                }else {
    //Chinese characters are not output as they are
                    stringBuilder.append(hanziString);
                }

            }
        } catch (BadHanyuPinyinOutputFormatCombination badHanyuPinyinOutputFormatCombination) {
    
            badHanyuPinyinOutputFormatCombination.printStackTrace();
        }
        String allPinYin = stringBuilder.toString();//Returns the full spelling of Chinese strings,例如：wŏshìzhōngzhòngguórén00
        return allPinYin;
    }

    /** * Get the pinyin of the first letter of a Chinese character string * @param hanZi '我是中国人00' * @return */
    public static String getFirstPinYin(String hanZi){
    
        //This class defines how to output Hanyu Pinyin.
        HanyuPinyinOutputFormat pinyinOutputFormat = new HanyuPinyinOutputFormat();
        pinyinOutputFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);//Output in lowercase,LOWERCASE:输出小写,UPPERCASE:输出大写
        pinyinOutputFormat.setToneType(HanyuPinyinToneType.WITH_TONE_MARK);//Output phonetic settings,WITH_TONE_MARK:Use phonetic symbols directly（必须设置WITH_U_UNICODE,否则会抛出异常）,WITH_TONE_NUMBER：1-4Numbers represent phonetic symbols,WITHOUT_TONE：没有音标
        pinyinOutputFormat.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE);//special phonetic symbolsü的设置,（WITH_V：用v表示ü,WITH_U_AND_COLON：用"u:"表示ü,WITH_U_UNICODE：直接用ü）

        char[] hanziChars = hanZi.trim().toCharArray();//去掉前后多余的空格,Convert to an array of Chinese characters
        StringBuilder stringBuilder = new StringBuilder();
        try {
    
            for (int i = 0; i < hanziChars.length; i++) {
    
                String hanziString = Character.toString(hanziChars[i]);//Get a single Chinese character,例如‘中’
                if(hanziString.matches("[\\u4e00-\\u9fa5]")){
    //判断是否是汉字
                    String[] pinYinAll = PinyinHelper.toHanyuPinyinStringArray(hanziChars[i],pinyinOutputFormat);//Get all the pronunciations of this Chinese character,For example, Zhong is a polyphonic word,其结果就是['zhōng','zhòng']
                    String firstString = Character.toString(pinYinAll[0].charAt(0));//The first character to go to the first pinyin is the first letter of Chinese characters
                    stringBuilder.append(firstString);
                }else {
    //Chinese characters are not output as they are
                    stringBuilder.append(hanziString);
                }
            }
        } catch (BadHanyuPinyinOutputFormatCombination badHanyuPinyinOutputFormatCombination) {
    
            badHanyuPinyinOutputFormatCombination.printStackTrace();
        }
        String allPinYin = stringBuilder.toString();//Returns the initial pinyin of a Chinese string
        return allPinYin;
    }
}

输出结果

wŏshìzhōngguórén00
