java-汉字转拼音

1、引入jar包

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

2、代码

/**** 将汉字转成拼音(取首字母或全拼)* @param hanzi* @param full 是否全拼 true-全拼 false-首字母*             如哈尔滨  haerbin    heb* @return*/
public static String convertHanzi2Pinyin(String hanzi,boolean full)
{/**** ^[\\u2E80-\\u9FFF]+$ 匹配所有东亚区的语言* ^[\\u4E00-\\u9FFF]+$ 匹配简体和繁体* ^[\\u4E00-\\u9FA5]+$ 匹配简体*/String regExp="^[\\u4E00-\\u9FFF]+$";StringBuffer sb=new StringBuffer();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))//是汉字，则转拼音{pinyin=convertSingleHanzi2Pinyin(unit);if(full){sb.append(pinyin);}else{sb.append(pinyin.charAt(0));}}else{sb.append(unit);}}return sb.toString();
}
/**** @param str 源字符串* @param regex 正则表达式* @return 是否匹配*/
public static boolean match(String str,String regex)
{Pattern pattern=Pattern.compile(regex);Matcher matcher=pattern.matcher(str);return matcher.find();
}
/**** 将单个汉字转成拼音* @param hanzi* @return*/
private static String convertSingleHanzi2Pinyin(char hanzi)
{HanyuPinyinOutputFormat outputFormat = new HanyuPinyinOutputFormat();outputFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);String[] res;StringBuffer sb=new StringBuffer();try {res = PinyinHelper.toHanyuPinyinStringArray(hanzi,outputFormat);sb.append(res[0]);//对于多音字，只用第一个拼音} catch (Exception e) {e.printStackTrace();return "";}return sb.toString();
}
public static void main(String[] args) {  //全拼System.out.println("哈尔滨:"+"全拼->"+convertHanzi2Pinyin("哈尔滨",true));//首字母System.out.println("哈尔滨:"+"首字母->"+convertHanzi2Pinyin("哈尔滨",false));
}

3、输出结果

       哈尔滨:全拼->haerbin
       哈尔滨:首字母->heb
