              XSSFCell cell;

              cell=row.createCell(1);
              cell.setCellValue("ID");
              cell=row.createCell(2);
              cell.setCellValue("area_info_id");

Use the header related function to set your header.

Header header = spreadsheet.getHeader();
header.setLeft("Left");
header.setCenter("Center");
header.setRight("Right");
