1.TODO 目前使用ISO8859-1编码作为输入！ PRivate String convertEncoding(String requestxml) { String temp = ""; try { temp = new String(requestXML.getBytes("ISO8859-1"), "UTF-8"); } catch (UnsupportedEncodingException e) { Assert.state(false, e.getMessage()); } return temp; }

==============================================================

//工具类

public class ConvertToolUtils { public static String gbk2iso(String src) { return convertEncoding(src, "GBK", "ISO-8859-1"); } public static String iso2gbk(String src) { return convertEncoding(src, "ISO-8859-1", "GBK"); } public static String convertEncoding(String source, String sourceEncoding, String targetEncoding) { try { if (source == null || source.equals("")) { return ""; } else { return new String(source.getBytes(sourceEncoding), targetEncoding); } } catch (Exception e) { return ""; } } public static int ConvertStrNum2IntNum(String strNum) { int Num = 0; try { if (null == strNum || strNum.trim().equals("")) { Num = 0; } else { Num = Integer.parseInt(strNum); }

} catch (Exception e) {

Num = 0; e.printStackTrace(); } return Num; } } 使用方式：

requestXML = ConvertToolUtils.convertEncoding(requestXML,"ISO8859-1","UTF-8");

=======================================

public String getUTF8XMLString(String xml) {// A StringBuffer ObjectStringBuffer sb = new StringBuffer();sb.append(xml);String xmString = "";String xmlUTF8 = "";try {xmString = new String(sb.toString().getBytes("UTF-8"));xmlUTF8 = URLEncoder.encode(xmString, "UTF-8");//加码//java.net.URLDecoder.decode(str,"UTF-8");//解码System.out.println("utf-8 编码：" + xmlUTF8);} catch (UnsupportedEncodingException e) {// TODO Auto-generated catch blocke.printStackTrace();}// return to String Formedreturn xmlUTF8;}
