ZipOutputStream导出压缩文件

1.在BidMultiOperateAction中添加一个新的actionType=‘BatchExportProvinceGrade’，调用方法如下，

   /**

     * 多选标的批量导出分省公司评分模板ZIP

     *

     * @param request

     * @param response

     * @param form

     */

    private void batchExportProvinceGrade(HttpServletRequest request, HttpServletResponse response, BidForm form)

        throws Exception

 

该方法类似现有的exportProvinceGrade，方法体如下：

 

        IBidBizService objBidBizService = DynamicDelegate.getService(IBidBizService.class);

        IBidIssueBizService objBidIssueBizService = DynamicDelegate.getService(IBidIssueBizService.class);

        ZipOutputStream objZipOutputStream = null;

        // 获取io流

        objZipOutputStream = new ZipOutputStream(getDownloadOutputStream(response, "123.zip"));

 

        String[] arrBidIds = form.getIdList();

        BidVO objBidVO = null;

        for (String strBidId : arrBidIds) {

 

            List<QueryCondition> lstQC = new ArrayList<QueryCondition>(1);

            lstQC.add(new QueryCondition("AND", "", "bidId", "=", strBidId, ""));

            List<BidVO> lstBidVO = objBidBizService.queryBidInfoList(lstQC, 1, Integer.MAX_VALUE);

            if (lstBidVO.size() > 0) {

                objBidVO = lstBidVO.get(0);

            } else {

                objBidVO = objBidBizService.readBid(strBidId);

            }

            String strProvinceName = objBidVO.getProvinceName();

            String strBidName =

                StringUtils.isBlank(strProvinceName) ? objBidVO.getBidName() : objBidVO.getBidName() + "（"

                    + strProvinceName + "）";

            objBidVO.setBidName(strBidName);

            String strFileName = strBidName + "_分省公司评分模板.xls";

            objZipOutputStream.putNextEntry(new ZipEntry(strFileName));

            objBidIssueBizService.exportProvinceGrade(objBidVO, objZipOutputStream);

        }

        objZipOutputStream.close();

 

【注】这里的zip文件命名要采用“项目名称_分省公司评分模板.zip”的格式，这里要通过标的读取项目名称信息。

 

2.修改ProvinceGradeModelExcel.java，删除 行201的 os.close(); 代码。

 

3.保留现有的在标的上逐个导出该标的的分省公司评分模板的功能，修改BidMultiOperateAction.exportProvinceGrade方法

在response.flushBuffer();代码行前添加os.close();  。
