GBK编码项目解决中文乱码

时间：2011-04-11 来源：战地蜗牛

前提：SSH框架下项目编码类型：GBK

提交方式1：表单提交中文参数：

String keyword=””;

keyword=URLEncoder.encode(request.getParameter("keyword"), "ISO-8859-1");

keyword=this.unescape(keyword);

提交方式2：URL地址提交中文参数：


String keyword=””;
keyword=URLEncoder.encode(request.getParameter("keywords"), "GBK");
keyword=this.unescape(keyword);

使用的unescape(String str)方法如下

public static String unescape(String src) throws UnsupportedEncodingException { 

         StringBuffer tmp = new StringBuffer(); 

         tmp.ensureCapacity(src.length()); 

         int lastPos = 0, pos = 0; 

         char ch; 

         while (lastPos < src.length()) { 

            pos = src.indexOf("%", lastPos); 

            if (pos == lastPos) { 

               if (src.charAt(pos + 1) == 'u') { 

                  ch = (char) Integer.parseInt(src.substring(pos + 2, pos + 6), 16); 

                  tmp.append(ch); 

                  lastPos = pos + 6; 

               } 

               else { 

                  ch = (char) Integer.parseInt(src.substring(pos + 1, pos + 3), 16); 

                  tmp.append(ch); 

                  lastPos = pos + 3; 

               } 

            } 

            else { 

               if (pos == -1) { 

                  tmp.append(src.substring(lastPos)); 

                  lastPos = src.length(); 

               } 

               else { 

                  tmp.append(src.substring(lastPos, pos)); 

                  lastPos = pos; 

               } 

            } 

         } 

         String currentTmp =   tmp.toString(); 

//         return currentTmp;

         return new String(currentTmp.getBytes("ISO-8859-1"),"GBK");

 

      }
