程序里面用到了开源的包，可以将汉语转成全拼或者缩写，代码如下：

         } 
          catch (BadHanyuPinyinOutputFormatCombination e1) { 
             e1.printStackTrace(); 
         } 
          return t4; 
  } 
    
//  返回中文的首字母 
   public  static String getPinYinHeadChar(String str) { 

  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 
   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) { 
  System.out.println(getPingYin( "綦江县")); 
  System.out.println(getPinYinHeadChar( "綦江县")); 
  System.out.println(getCnASCII( "綦江县")); 
 }
结果如下：
