支持转换的有:
import java.io.*; /** * 字符编码转换 */ public class FormatTrans{ /** * 说明:将输入字符串从"UTF-8"转为"UTF-8" * @param strIn --待转换字符串 * @return 转换后的字符串 */ public static String UTF8ToUnicode(String strIn) { byte[] b; String strOut = null; if (strIn == null || (strIn.trim()).equals("")) return strIn; try { strOut = new String(strIn.getBytes("UTF-8"), "iso-8859-1"); //new String(b,"GBK"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } return strOut; } /** * 说明:将输入字符串从"iso-8859-1"转为"UTF-8" * @param strIn --待转换字符串 * @return 转换后的字符串 */ public static String UnicodeToUTF8(String strIn) { byte[] b; String strOut = null; if (strIn == null || (strIn.trim()).equals("")) return strIn; try { strOut = new String(strIn.getBytes("iso-8859-1"), "UTF-8"); //new String(b,"ISO8859_1"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } return strOut; } /** * 说明:将输入字符串从"iso-8859-1"转为"GBK" * @param strIn --待转换字符串 * @return 转换后的字符串 */ public static String UnicodeToGB(String strIn) { byte[] b; String strOut = null; if (strIn == null || (strIn.trim()).equals("")) return strIn; try { strOut = new String(strIn.getBytes("iso-8859-1"), "GBK"); //new String(b,"ISO8859_1"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } return strOut; } /** * 说明:将输入字符串从"iso-8859-1"转为"GB2312" * @param strIn --待转换字符串 * @return 转换后的字符串 */ public static String UnicodeToGB2312(String strIn) { byte[] b; String strOut = null; if (strIn == null || (strIn.trim()).equals("")) return strIn; try { strOut = new String(strIn.getBytes("iso-8859-1"), "GB2312"); //new String(b,"GB2312"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } return strOut; } /** * 说明:将输入字符串从"UTF-8"转为"GBK" * @param strIn --待转换字符串 * @return 转换后的字符串 */ public static String UTF8ToGB(String strIn) { String strOut = null; if (strIn == null || (strIn.trim()).equals("")) return strIn; try { strOut = new String(strIn.getBytes("UTF-8"), "GBK"); } catch (Exception e) { e.printStackTrace(); } return strOut; } /** * 说明:将输入字符串从"GBK"转为"UTF-8" * @param strIn --待转换字符串 * @return 转换后的字符串 */ public static String GBToUTF8(String strIn) { String strOut = null; if (strIn == null || (strIn.trim()).equals("")) return strIn; try { strOut = new String(strIn.getBytes("GBK"), "UTF-8"); } catch (Exception e) { e.printStackTrace(); } return strOut; } /** * 说明:将输入字符串从"GBK"转为"iso-8859-1" * @param strIn --待转换字符串 * @return 转换后的字符串 */ public static String GBToUnicode(String strIn) { String strOut = null; if (strIn == null || (strIn.trim()).equals("")) return strIn; try { strOut = new String(strIn.getBytes("GBK"), "iso-8859-1"); } catch (Exception e) { e.printStackTrace(); } return strOut; } /** * 说明:将输入字符串从"GB2312"转为"iso-8859-1" * @param strIn --待转换字符串 * @return 转换后的字符串 */ public static String GB2312ToUnicode(String strIn) { String strOut = null; if (strIn == null || (strIn.trim()).equals("")) return strIn; try { strOut = new String(strIn.getBytes("GB2312"), "iso-8859-1"); } catch (Exception e) { e.printStackTrace(); } return strOut; } public static byte[] Base64ToByte(String strIn){ byte[] bytes = null; try { bytes = new sun.misc.BASE64Decoder().decodeBuffer(strIn); } catch (IOException e) { e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. } return bytes; } }
