[JAVA篇]有关手机中文问题传输的解决办法

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  -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;
}
