平时开发中，经常遇到中文转换成中文转换成Unicode编码和Unicode编码转换成中文的问题，国际化的时候，也要遇到这个问题，
现在我就把中网上找的很自己学习的经验，共享给大家了。闲话少说，步入正题,
Java代码如下：
 
  
   
    [java] 
    view plain
     copy
     
   
  
  package test.com.gjob.services;  
   import java.util.Properties;  
    public class Test {   
           public static void main(String[] args) {   
           String s = "简介";   
          String tt = gbEncoding(s);   
   //       String tt1 = "你好，我想给你说一个事情";  
          System.out.println(decodeUnicode("\\u7b80\\u4ecb"));   
   //       System.out.println(decodeUnicode(tt1));   
          System.out.println(HTMLDecoder.decode("中国"));  
          String s1 = "\u7b80\u4ecb";  
          System.out.println(s.indexOf("\\"));  
         }   
        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();   
             }   
         }
