导出到Excel（Java List，HtmlDataTable，rich：dataTable）

Question

是否有一些简单的方法如何将Java List（或rich：dataTable或htmlDataTable，基于dataList）导出到格式化的excel表？

datalist示例：

private List<BDE> dataList;
session = DaoSF.getSessionFactory('R').openSession();   
Criteria criteria = session.createCriteria(BDE.class);
  {some restrictions...}
dataList = criteria.list();

我使用AnalysisTable将其导出到csv，但似乎没有太多用户友好的导出..

谢谢

更新：我找到了primefaces解决方案，它确实有效。其余的事情是，要创建简单的格式化xls表，你有没有一些提示？

Answer 1

    private List<BDE> dataList;
session = DaoSF.getSessionFactory('R').openSession();   
Criteria criteria = session.createCriteria(BDE.class);
  {some restrictions...}
dataList = criteria.list();

//Excel creation after your dataList has been generated 
FileOutputStream fos = new FileOutputStream("sth.xls");
//Give your file path may be to desktop so that you can see
org.apache.poi.hssf.usermodel.HSSFWorkbook workBook = new HSSFWorkbook();
Row row = null;
Cell cell = null;
Sheet sheet1 = workBook.createSheet();
    for(int rowNo = 0;rowNo<dataList.size;rowNo++){
     row= sheet1.createRow(rowNo);
      for(int cellNo = 0;cellNo <2;cellNo++){//It would go to 0th and 1st row
        cell = row.createCell(cellNo);
            cell.setCellValue("Some of your value");
            }
    }
