在西安做项目时遇到的一个文件下载文件名乱码的问题，下面是解决方案：

//输出文件流
    response.setContentType("application/octet-stream;charset=ISO8859-1");
   String agent = request.getHeader("USER-AGENT");
   if (null != agent && -1 != agent.indexOf("MSIE")){
    response.setHeader("Content-Disposition","attachment;" + "filename=" + URLEncoder.encode( file.getName() , "UTF8"));
   }
   else if (null != agent && -1 != agent.indexOf("Mozilla")){
    response.setHeader("Content-Disposition","attachment;" + "filename=" + new String(file.getName().getBytes("UTF-8"),"ISO8859-1"));
   }
   else {
      response.setHeader("Content-Disposition","attachment;filename=" + file.getName() );
   }
    java.io.FileInputStream fr = new java.io.FileInputStream(fpath);
         java.io.InputStreamReader is = new java.io.InputStreamReader(fr,"ISO8859-1");
         java.io.BufferedReader br=new java.io.BufferedReader(is);
   out = response.getOutputStream();

   int i = 0;
   while((i= br.read()) != -1){
             out.write(i);
         }

List按内部存储的object的属性排序

逆水深寒 — Tue, 21 Jul 2009 06:03:00 GMT

private List sortFieldListByRowIndex(List fieldList){
  Comparator comparator = new Comparator(){
   public int compare(DynamicFormField f1, DynamicFormField f2) {
     if(f1.getRowIndex()!=f2.getRowIndex()){
         return f1.getRowIndex()-f2.getRowIndex();
      }else if(f1.getColIndex()!=f2.getColIndex()){
       return f1.getColIndex()-f2.getColIndex();
      }else{
       return (int) (f1.getId() - f2.getId());
      }
   }
  };
  Collections.sort(fieldList, comparator);
  return fieldList;
}
这是工作中使用过的一个例子。
对fieldList中DynamicFormField对象先按其rowIndex排序后按colIndex排序
