easyPoi框架的excel导入导出
作者:互联网
一 导出
<a-button @click="exportDataList" icon="download" type="success" style="margin-right: 8px">导出数据</a-button>
//导出表格 exportDataList () { //导出表格的查询条件 this.queryParam.type = this.activeKey //导出 exportData(this.queryParam).then(res => { //创建二进制数据对象 const blbo = new Blob([res], { type: 'application/vnd.ms-excel;charset=utf-8' }) //创建a标签 const link = document.createElement('a') //创建一个指向二进制文件的URL link.href = window.URL.createObjectURL(blbo) //文件名 link.download = '物流公司信息.xls' //触发下载 link.click() }) },
/** * 导出物流公司信息 * * @param fisLogisticsCompanyInfo 导出实体类 * @param commonQuery //查询参数 * @param response //http响应 */ @SneakyThrows @GetMapping("/logisticsCompany/export") @ApiOperation(value = "导出物流公司信息") public void export(FisLogisticsCompanyInfo fisLogisticsCompanyInfo, CommonQuery commonQuery, HttpServletResponse response) { //导出的查询条件 QueryWrapper<FisLogisticsCompanyInfo> autoQueryWrapper = QueryGenerator.initQueryWrapper(fisLogisticsCompanyInfo, commonQuery); //查询出所有要导出的数据 List<FisLogisticsCompanyInfo> fisLogisticsCompanyInfos = fisLogisticsCompanyInfoService.list(autoQueryWrapper); //利用导出工具类将数据导出 Workbook workbook = ExcelExportUtil.exportExcel(new ExportParams("物流公司信息", "container"), FisLogisticsCompanyInfo.class, fisLogisticsCompanyInfos); //写道输出流 workbook.write(response.getOutputStream()); }
二 下载导入
//导入向导按钮 点击调用importData方法
<a-button @click="importData" icon="upload" style="margin-right: 8px" type="plain">导入向导</a-button>
//触发组件的show方法 展示文件上传页面
importData () {
this.$refs.BImportFile.show()
},
//当前页面使用了文件上传组件
<b-import-file @ok="queryPage" :actionUrl="actionUrl" :des="des" ref="BImportFile" @download="download"/>
//引入文件上传组件
import BImportFile from '@/components/BImportFile'
//注册到组件
components: { MESSuperQuery, modalForm, BImportFile //封装好的导入组件 },
//点击组件的下载导入模板 触发组件的download
<div @click='download' class='upload-dragger'> <a-upload-dragger :headers='headers' :multiple='true' :openFileDialogOnClick='false' @change='handleChange' action='/api/storage/upload' name='file' > <p class='ant-upload-drag-icon'> <a-icon type='cloud-download' /> </p> <p class='ant-upload-text'>先下载要上传的模板</p> <p class='ant-upload-hint'> 支持扩展名:xls,xlsx </p> </a-upload-dragger> </div>
//向父组件传递事件
download() { this.$emit('download') },
//父组件接受子组件传来的事件 下载excel模板 download () { logisticsCompanyTemplate().then(res => { //创建二进制数据对象 const blbo = new Blob([res], { type: 'application/vnd.ms-excel;charset=utf-8' }) //创建a标签 const link = document.createElement('a') //创建一个指向二进制文件的URL link.href = window.URL.createObjectURL(blbo) link.download = '物流公司导入模板.xlsx' //点击a标签 link.click() }).catch((e) => { this.$message.warning('下载失败') }) },
/** * 下载物流公司导入模板 * * @return */ @SneakyThrows @GetMapping("/logisticsCompany/template") @ApiOperation(value = "物流公司导入模板") public void downTemplate(HttpServletResponse response) { //获取数据库中模板文件名称 String rfidTemplate = Global.getConfig("logisticsCompanyTemplate"); //获取bucketName 默认bootfile String bucketName = Global.getConfig("sys.file.bucketName", "bootfile"); //根据buckName和文件名称返回二进制流 S3Object object = minioTemplate.getObject(bucketName, rfidTemplate); IoUtil.copy(object.getObjectContent(), response.getOutputStream()); }
三 导入
<div class='upload-dragger' > <a-upload-dragger :beforeUpload='beforeFileUpload' :fileList='fileList' :headers='headers' :multiple='true' @change='handleChange' :action='actionUrl' name='file' > <p class='ant-upload-drag-icon'> <a-icon type='cloud-upload' /> </p> <p class='ant-upload-text'>上传要导入的文件</p> <p class='ant-upload-hint'> 支持扩展名:xls,xlsx </p> </a-upload-dragger> </div>
/** * 导入物流公司信息 * * @param file * @return */ @SneakyThrows @PostMapping("/uploadBom") public Result upload(@RequestParam("file") MultipartFile file) { List<FisLogisticsCompanyInfo> logisticsCompanyInfoList = FileUtil.importExcel(file, 0, 1, FisLogisticsCompanyInfo.class); logisticsCompanyInfoList = logisticsCompanyInfoList.stream().map(fisLogisticsCompanyInfo -> { fisLogisticsCompanyInfo.setUpdateBy(SecurityUtil.getUser().getUserId()); fisLogisticsCompanyInfo.setCreateBy(SecurityUtil.getUser().getUserId()); fisLogisticsCompanyInfo.setUpdateTime(new Date()); fisLogisticsCompanyInfo.setCreateTime(new Date()); return fisLogisticsCompanyInfo; }).collect(Collectors.toList()); fisLogisticsCompanyInfoService.saveBatch(logisticsCompanyInfoList); return Res.ok(); }
public static <T> List<T> importExcel(MultipartFile file, Integer titleRows, Integer headerRows, Class<T> pojoClass) { if (file == null) { return null; } ImportParams params = new ImportParams(); params.setTitleRows(titleRows); params.setHeadRows(headerRows); List<T> list = null; ZipSecureFile.setMinInflateRatio(-1.0d); try { list = ExcelImportUtil.importExcel(file.getInputStream(), pojoClass, params); } catch (NoSuchElementException e) { // System.out.println("excel文件不能为空"); throw new NoSuchElementException("excel文件不能为空"); } catch (Exception e) { System.out.println(e.getMessage()); // throw new NormalException(); throw new NoSuchElementException(e.getMessage()); } return list; }
