Java 汉字转拼音的具体实现及汉字声调处理

       之前在技术群里有群友问,java可以输出汉子的拼音么,可以带声调么,对于这个问题,java当然是可以的。之后就网上查询了一些方法,自己写了几个方法,下面就把我写的方法跟大家一起分享,欢迎各位技术牛批评指正。

    下面是代码部分,主要实现了java对汉字的判别,并且转换为拼音:

package com.zimu;

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;

public class GetPinyin {

	/**
	 * 得到 全拼
	 * 
	 * @param src
	 * @return
	 */
	public static String getPinYin(String src) {
		char[] t1 = null;
		t1 = src.toCharArray();
		String[] t2 = new String[t1.length];
		//t3是全部的拼音,不带声调
		HanyuPinyinOutputFormat t3 = new HanyuPinyinOutputFormat();
		t3.setCaseType(HanyuPinyinCaseType.LOWERCASE);
		t3.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
		t3.setVCharType(HanyuPinyinVCharType.WITH_V);
		
		//format是全部的拼音并且带声调
		HanyuPinyinOutputFormat format= new HanyuPinyinOutputFormat();
		format.setToneType(HanyuPinyinToneType.WITH_TONE_MARK);
		format.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE);
		
		
		
		String t4 = "";
		int t0 = t1.length;
		try {
			for (int i = 0; i < t0; i++) {
				// 判断是否为汉字字符
				if (java.lang.Character.toString(t1[i]).matches(
						"[\\u4E00-\\u9FA5]+")) {
//					t2 = PinyinHelper.toHanyuPinyinStringArray(t1[i], t3);
					t2 = PinyinHelper.toHanyuPinyinStringArray(t1[i], format);
					t4 += t2[0]+" ";
				} else {
					t4 += java.lang.Character.toString(t1[i]);
				}
			}
			return t4;
		} catch (BadHanyuPinyinOutputFormatCombination e1) {
			e1.printStackTrace();
		}
		return t4;
	}

	/**
	 * 得到中文首字母
	 * 
	 * @param str
	 * @return
	 * @throws BadHanyuPinyinOutputFormatCombination 
	 */
	public static String getPinYinHeadChar(String str) throws BadHanyuPinyinOutputFormatCombination {
		
		String convert = "";
		for (int j = 0; j < str.length(); j++) {
			char word = str.charAt(j);
			String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(word);
			if (pinyinArray != null) {
				convert += pinyinArray[0].charAt(0);
			} else {
				convert += word;
			}
		}
		return convert;
	}

	/**
	 * 将字符串转移为ASCII码
	 * 
	 * @param cnStr
	 * @return
	 */
	public static String getCnASCII(String cnStr) {
		StringBuffer strBuf = new StringBuffer();
		byte[] bGBK = cnStr.getBytes();
		for (int i = 0; i < bGBK.length; i++) {
			// System.out.println(Integer.toHexString(bGBK[i]&0xff));
			strBuf.append(Integer.toHexString(bGBK[i] & 0xff));
		}
		return strBuf.toString();
	}

	public static void main(String[] args) throws Exception {
		String cnStr = "我爱Ryan Albert"; //Ryan Albert是我的英文名,这里就不写我的中文名字了。
		System.out.println(getPinYin(cnStr));
		System.out.println(getPinYinHeadChar(cnStr));
	}

}
