本文介绍了一段Java代码实现将Unicode字符序列转换为字符串，并通过反序列化将其还原为原始字符串的过程。重点在于理解Unicode编码原理及Java中字符与字符串的处理方式。

public class Test
{
 public static void main(String[] args)
 {
 String s = "中转地设置导出模板";
 String tt = gbEncoding(s);
 }

 public static String gbEncoding(final String gbString)
 {
 char[] utfBytes = gbString.toCharArray();
 String unicodeBytes = "";
 for (int byteIndex = 0; byteIndex < utfBytes.length; byteIndex++)
 {
 String hexB = Integer.toHexString(utfBytes[byteIndex]);
 if (hexB.length() <= 2)
 {
 hexB = "00" + hexB;
 }
 unicodeBytes = unicodeBytes + "\\u" + hexB;
 }
 System.out.println("unicodeBytes is: " + unicodeBytes);
 return unicodeBytes;
 }

 public static String decodeUnicode(final String dataStr)
 {
 int start = 0;
 int end = 0;
 final StringBuffer buffer = new StringBuffer();
 while (start > -1)
 {
 end = dataStr.indexOf("\\u", start + 2);
 String charStr = "";
 if (end == -1)
 {
 charStr = dataStr.substring(start + 2, dataStr.length());
 }
 else
 {
 charStr = dataStr.substring(start + 2, end);
 }
 char letter = (char) Integer.parseInt(charStr, 16); // 16进制parse整形字符串。
 buffer.append(new Character(letter).toString());
 start = end;
 }
 return buffer.toString();
 }
}
