JEECG_ExcelExportServer批量数据导出超过60000条

项目上线了,结果导出数据时发现只能导出6w条,好奇怪啊...

本地试了试结果每次都卡在10w条. orz

开始扒拉批量导出

 ExcelBatchExportServer server = new ExcelBatchExportServer();
            server.init(exportParams,TTransLine.class);
            server.write(exportList);
            Workbook workbook = server.get();

奇了怪了,超过10w条创建了新的sheet

回来看看源码....额...额...

最终只要稍作修改..完事...

        List exportList = new ArrayList<>();
        int pageSize = 10000;
        long pageMax = (count / 10000) + 1;
 
        for (int i = 0; i < pageMax; i++) {
            queryWrapper.last(" limit " + i * pageSize + "," + pageSize);
            List pageList = tTService.list(queryWrapper);
            if (pageList != null) {
                exportList.addAll(pageList);
            }
        }
        // Step.3 AutoPoi 导出Excel
        ModelAndView mv = new ModelAndView(new JeecgEntityExcelView());
        //此处设置的filename无效 ,前端会重更新设置一下
        mv.addObject(NormalExcelConstants.FILE_NAME, title);
        mv.addObject(NormalExcelConstants.CLASS, TT.class);
        ExportParams exportParams = new ExportParams(title + "报表", "导出人:" + sysUser.getRealname(), title);
        //        -------------关键代码--
        exportParams.setType(ExcelType.XSSF);
        //        -------------关键代码--
        exportParams.setImageBasePath(upLoadPath);
        mv.addObject(NormalExcelConstants.PARAMS, exportParams);
        mv.addObject(NormalExcelConstants.DATA_LIST, exportList);
        return mv;
