java 实现中文转化为拼音代码 汉字转化为拼音源码分享

对于我们WEB开发者,经常会用到把中文转化为拼音的功能, 下面我分享一下总结的代码:

需要导入lib pinyin4j-2.5.0.jar

下载pinyin4j-2.5.0.jar

public static Set getPinyin(String src) {
		if (src != null && !src.trim().equalsIgnoreCase("")) {
			char[] srcChar;
			srcChar = src.toCharArray();
			// 汉语拼音格式输出类
			HanyuPinyinOutputFormat hanYuPinOutputFormat = new HanyuPinyinOutputFormat();

			// 输出设置，大小写，音标方式等
			hanYuPinOutputFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
			hanYuPinOutputFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
			hanYuPinOutputFormat.setVCharType(HanyuPinyinVCharType.WITH_V);

			String[][] temp = new String[src.length()][];
			for (int i = 0; i < srcChar.length; i++) {
				char c = srcChar[i];
				// 是中文或者a-z或者A-Z转换拼音(我的需求，是保留中文或者a-z或者A-Z)
				if (String.valueOf(c).matches("[\\u4E00-\\u9FA5]+")) {
					try {
						temp[i] = PinyinHelper.toHanyuPinyinStringArray(
								srcChar[i], hanYuPinOutputFormat);
					} catch (BadHanyuPinyinOutputFormatCombination e) {
						e.printStackTrace();
					}
				} else if (((int) c >= 65 && (int) c <= 90)
						|| ((int) c >= 97 && (int) c <= 122)) {
					temp[i] = new String[] { String.valueOf(srcChar[i]) };
				} else {
					temp[i] = new String[] { "" };
				}
			}
			String[] pingyinArray = Exchange(temp);
			Set pinyinSet = new HashSet();
			for (int i = 0; i < pingyinArray.length; i++) {
				pinyinSet.add(pingyinArray[i]);
			}
			return pinyinSet;
		}
		return null;
