解释W号代表的意思：
* 代表L合法的字D?
0 * 17 * * ? Q表C在每天? PM ?5:59之间的每一分钟启动scheduler

? 表示没D指定
如果同时指定"一月哪??星期"Q可能两者对应不h
0 0,15,30,45 * * * ? Q表C每刻钟启动scheduler
所以推荐用法是其中一个指定|另一个用?指定

/ 表示旉的增?
0 0/15 * * * ? Q表C每刻钟启动scheduler

- 表示值的范围
0 45 3-8 ? * *

L 如果用在"一月哪?D上Q表CZ个月的最后一天；如果用在"星期"D上。表CZ个星期的最后一天（星期六）
0 0 8 L * ? Q表C每个月最后一天的8点启动scheduler

W 表示最靠近l定旉的一天，Q必L星期一到星期五Q?/p>

      response.setContentType("APPLICATION/OCTET-STREAM");

      response.setHeader("Content-Disposition", "attachment; filename=\""+ Chinese.toPage(fileName) + "\"");

      但这有个不好的就是它只能打开一个EXCEL的一个工作簿Q如果数据量非常大的话，后面的数据会丢失Q根据这个BUGQ我重新做了一个动态生成EXCEL工作薄的例子Q以方便后面Ҏ应用的改造?br />
 首先从数据库里取数据的时候，不知道行Q列Q这样就需要一个动作，把RS转换成一个VECTORQ此对象里每一行也是一个VECTOR
  public static Vector ResultSetToVector(ResultSet rs) {
    try {
      Vector rows = new Vector();
      ResultSetMetaData rsmd = rs.getMetaData();
      Vector columnHeads = new Vector();

      for (int i = 1; i <= rsmd.getColumnCount(); i++) {
        columnHeads.addElement(rsmd.getColumnName(i));
      }

      Vector currentRow;
      while(rs.next()){
        currentRow = new Vector();
        for (int i = 1; i <= rsmd.getColumnCount(); i++) {
          currentRow.addElement(Chinese.fromDatabase(rs.getString(i)));
        }
        rows.addElement(currentRow);
      }
      return rows;
    }
    catch (Exception err) {
      Log.printError(err, "", "", log);
      return null;
    }
    finally{
      try {
        if(rs!=null){
          rs.close();
          rs = null;
        }
      }
      catch (Exception ex) {
      }
    }

 再通过写一个方法，把VECTOR的值放到EXCEL里去?br />   ResultSetMetaData rmeta = rs.getMetaData();
   int numColumns = rmeta.getColumnCount();//取多行
   String fileNametemp = "c:\\"+fileName;
   fileNametemp = fileNametemp.substring(0,fileNametemp.lastIndexOf("."))+CTime.getTime(12)+".xls";
   
   java.io.File file = new java.io.File(fileNametemp);
   if (file.exists()) {
    file.delete();
   }
   String rows_temp = request.getParameter("rows");//面传过来的每个SHEET可以存放的条?br />   if (rows_temp == null){
    rows_temp = "20000";// 一个表单默?0000行?br />   }
   int count_rows = Integer.parseInt(rows_temp);
   WritableWorkbook wb = Workbook.createWorkbook(file);
     
    Vector v_Rs = RsToVector.ResultSetToVector(rs);// 把RS的D{换成VECTOR
   boolean fg = true;    
    if (v_Rs != null) {
    int a = v_Rs.size();    
    int sheet_count = a / count_rows;    
    if (sheet_count >0){//大于0Q则需要多个SHEET
     for (int i = 0;i<sheet_count;i++){
      Vector temp_v = new Vector();
      for (int b = i* count_rows ;b<(i+1) * count_rows ;b++){
       
       temp_v.add(v_Rs.get(b));
      }      
      writeExcel(wb,"sheet"+i,temp_v,numColumns,sheet_count);//EXCEL对象、单元薄名、数据、行数、第几个单元薄     ?br />     }

以上Ҏ也有一个问题，是当程序写100000条数据以后，速度会慢下来Q我看了WritableWorkbook 的构造方法的时候，可以生成一个OUTPUTSTREAM对象的，我想可以用这个来做，速度可能会上去，但具体也没有试，如何有哪位哥们试q了Q把性能跟兄弟分享一下！谢谢了！
