java 就是好，开源的jar包超级多

下面的需要pinyin4j-2.5.0.jar 该jar包，来自http://www.baidu.com/s?wd=pinyin4j-2.5.0.zip&n=2&inputT=1273 或者去sourceforge 上面搜索

package hanzi2pinyin;

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 Pinyin {

public static String getPinYin(String src) {
char[] t1 = null;
t1 = src.toCharArray();
// System.out.println(t1.length);
String[] t2 = new String[t1.length];
// System.out.println(t2.length);
// 设置汉字拼音输出的格式
HanyuPinyinOutputFormat t3 = new HanyuPinyinOutputFormat();
t3.setCaseType(HanyuPinyinCaseType.LOWERCASE);
t3.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
t3.setVCharType(HanyuPinyinVCharType.WITH_V);
String t4 = "";
int t0 = t1.length;
try {
for (int i = 0; i < t0; i++) {
// 判断是否为汉字字符
// System.out.println(t1[i]);
if (Character.toString(t1[i]).matches("[\\u4E00-\\u9FA5]+")) {
t2 = PinyinHelper.toHanyuPinyinStringArray(t1[i], t3);// 将汉字的几种全拼都存到t2数组中
t4 += t2[0];// 取出该汉字全拼的第一种读音并连接到字符串t4后
} else {
// 如果不是汉字字符，直接取出字符并连接到字符串t4后
t4 += Character.toString(t1[i]);
}
}
} catch (BadHanyuPinyinOutputFormatCombination e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return t4;
}


public static String getPinYinHeadChar(String str) {
String convert = "";
for (int j = 0; j < str.length(); j++) {
char word = str.charAt(j);
//提取汉字的首字母
String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(word);
if (pinyinArray != null) {
convert += pinyinArray[0].charAt(0);
} else {
convert += word;
}
}
return convert;
}

public static String getCnASCII(String cnStr) {
StringBuffer strBuf = new StringBuffer();
//将字符串转换成字节序列
byte[] bGBK = cnStr.getBytes();
for (int i = 0; i < bGBK.length; i++) {
// System.out.println(Integer.toHexString(bGBK[i] & 0xff));
//将每个字符转换成ASCII码
strBuf.append(Integer.toHexString(bGBK[i] & 0xff));
}
return strBuf.toString();
}

public static void main(String[] args) {
String cnStr = "欢迎访问我的百度空间--风云之家";
System.out.println(getPinYin(cnStr)); //获取全拼
System.out.println(getPinYinHeadChar(cnStr));//获取首字母
System.out.println(getCnASCII(cnStr));//获取ascii码
}

运行结果：
