Java中将汉字转为拼音

Posted 2020-07-22

首先，加入pinyin4j-2.5.0.jar包，jar包在源码中有

写工具类

public class PingYinUtil {  
    /** 
     * 将字符串中的中文转化为拼音,其他字符不变 
     *  
     * @param inputString 
     * @return 
     */  
    public static String getPingYin(String inputString) {  
        HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();  
        format.setCaseType(HanyuPinyinCaseType.LOWERCASE);  
        format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);  
        format.setVCharType(HanyuPinyinVCharType.WITH_V);  
   
        char[] input = inputString.trim().toCharArray();  
        String output = "";  
   
        try {  
            for (int i = 0; i < input.length; i++) {  
                if (java.lang.Character.toString(input[i]).matches("[\\u4E00-\\u9FA5]+")) {  
                    String[] temp = PinyinHelper.toHanyuPinyinStringArray(input[i], format);  
                    output += temp[0];  
                } else  
                    output += java.lang.Character.toString(input[i]);  
            }  
        } catch (BadHanyuPinyinOutputFormatCombination e) {  
            e.printStackTrace();  
        }  
        return output;  
    }  
    /**   
     * 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();     
    }     
    /**   
     * 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();     
    }    
}

然后直接调接口就行

public class Test {  
    public static void main(String[] args) {  
        String str="汉字转拼音";  
        System.out.println("原为："+str);  
        System.out.println("转换后为："+PingYinUtil.getPingYin("汉字转拼音"));  
    }  
}

运行结果
