有关手机中文问题传输的解决办法

<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script> 服务器到客户端： ---------------------------------------------------------------------- 下面代码是服务器端把字符写到Client端，经过gbEncoding()方法，所有的字符编码成：/uXXXX. ---------------------------------------------------------------------- 代码:-------------------------------------------------------------------------------- /** * Write the String data * * @param out * @param value */ public static void writeUnicode(final DataOutputStream out, final String value) throws ActionException { try { final String unicode = StringFormatter.gbEncoding( value ); final byte[] data = unicode.getBytes(); final int dataLength = data.length; System.out.println( "Data Length is: " dataLength ); System.out.println( "Data is: " value ); out.writeInt( dataLength ); out.write( data, 0, dataLength ); } catch (IOException e) { throw new ActionException( IMDefaultAction.class.getName(), e.getMessage() ); } } -------------------------------------------------------------------------------- ---------------------------------------------------------------------- 以下代码是gbEncoding()方法，把双字节字符转换成/uXXXX,ASIIC码在前面补00。 ---------------------------------------------------------------------- /** * This method will encode the String to unicode. * * @param gbString * @return */ 代码:-------------------------------------------------------------------------------- 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; } -------------------------------------------------------------------------------- ---------------------------------------------------------------------- 在客户端收到服务器的数据，先将其一个一个字符解码。双字节显示正常。 ---------------------------------------------------------------------- 代码:-------------------------------------------------------------------------------- /** * This method will decode the String to a recognized String * in ui. * @param dataStr * @return */ private StringBuffer 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; } -------------------------------------------------------------------------------- ---------------------------------------------------------------------- 客户端到服务器： ---------------------------------------------------------------------- 客户端使用下面方法把手机端的字符编码成ISO-8859-1,传给服务器。 ---------------------------------------------------------------------- 代码:-------------------------------------------------------------------------------- /** * write the String data * @param value * @param outData */ private void writeSjis(DataOutputStream outData, String value) { try { byte[] data = null; // data = ( value ).getBytes( "UTF-8" ); data = ( value ).getBytes( "ISO8859_1" ); outData.writeInt(data.length); outData.write(data, 0, data.length); System.out.println(" data.length: " data.length); System.out.println(" data.value: " value); } catch (Exception ex) { System.out.println(" write error "); ex.printStackTrace(); } } -------------------------------------------------------------------------------- ---------------------------------------------------------------------- 服务器端收到客户端字符流，是用下面方法将其转为UTF-8，以后的操作都是基于UTF-8编码。SQLServer可能会由于内吗不通有不同的变换，所以存取数据库是还要是具体的DB内码作相应的处理。 ---------------------------------------------------------------------- 代码:-------------------------------------------------------------------------------- /** * * @param iso * @return */ public static String isoToUtf( final String iso ) { String utfString = iso; if( iso != null ) { try { utfString = new String( iso.getBytes( "ISO-8859-1" ), "UTF-8" ); } catch ( UnsupportedEncodingException e ) { utfString = iso; } } else { utfString = ""; } return utfString; } 注： 本方法应该不是最有效的，但是只要手机支持unicode的gb2312编码，应该都可以显示正常。 不正之处，请各位到:http://www.ebds.com.cn/bbs/讨论讨论。
