使用poi实现springMVC的Excel导入导出

需要jar包：poi.jar poi-ooxml.jar poi-ooxml-schemas.jar xbean.jar(用于解析excel2007)

controller层导出:

 1 // 导出excel
 2         if (action != null && action.equals("export")) {
 3             List<LoadPriceShipownerQueryItem> exportList = priceShipownerService
 4                     .getPriceShipownerListByCondition(condition, pagingInfo);
 5             HSSFWorkbook workbook = priceShipownerService
 6                     .priceShipownerExportExcel(exportList);
 7             String filename = "priceShipowner.xls";
 8             OutputStream out = response.getOutputStream();
 9             response.setHeader("Content-disposition", "attachment;filename="
10                     + URLEncoder.encode(filename, "UTF-8"));
11             response.setContentType("application/msexcel;charset=UTF-8");
12             workbook.write(out);
13             if (out != null) {
14                 out.close();
15             }
16             workbook.close();
17         }

controller层导入：
