struts2 + ajax 中文乱码问题解决

 

在发送ajax请求之前,对参数escape()两次( 例:name=escape(escape("张三")); ),然后再发送请求到服务器,服务器接收参数后,对参数unescape(),就可以得到正确的参数( 例:String name=unescape(request.getParameter("name")); ).

 

 private String unescape(String src) {
  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;
    }
   }
  }

  return tmp.toString();
