1.在服务器（Struts Action）中将中文转化为Unicode字符编码 2.在手机端J2ME中将Unicode码再转换成中文。 1.服务器端 /**
* 转换为Unicode字符 并输出
* @param servletOutputStream ( response.getOutputStream() )
* @param value (传输的值)
*/
public static void writeUnicode(final ServletOutputStream servletOutputStream, final String value) {
try {
final String unicode = gbEncoding(value);
final byte[] data = unicode.getBytes();
servletOutputStream.write(data); // 然后写出转化后的字符串
} catch (IOException e) {
}
} 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 ActionForward TestU(ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response) {
try {
this.writeUnicode(response.getOutputStream(), "齐鲁软件设计大赛济南职业学院");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
} 2.客户端 private void con() {
HttpConnection hc;
try {
hc = (HttpConnection) Connector
.open("http://localhost:8080/stu/roomReadPhone.do?meth=TestU");
InputStream is = hc.openInputStream();
String content = "";
while (true) {
int ch = is.read();
if (ch == -1) {
break;
}
content += (char) ch;
}
String str = new String(content.getBytes("ISO8859-1"), "GBK");
// #style messageAlert
Alert alert = new Alert("", this.decodeUnicode(str), null, AlertType.INFO);
alert.setTimeout(Alert.FOREVER);
midlet.getDisplay().setCurrent(alert);
} catch (IOException e) {
System.out.println(e + "kkkk");
}
}
//反编为中文
private String decodeUnicode(final String dataStr) {
final StringBuffer buffer = new StringBuffer();
String[] s = this.split(dataStr, "\\\\u");
for(int i = 1; i < s.length; i++){
String st = s;
if(i==s.length-1){
st = s.substring(2);
}
char c = (char) Integer.parseInt(st, 16); // 16进制parse整形字符串。
System.out.println("dd:" + c);
buffer.append(new Character(c).toString());
}
return buffer.toString();
}

public String[] split(String original, String regex) {

// 存储取子串时起始位置
