java String 编码格式转换

// 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; 

 } 



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");
