excel导出标准化

news 来源：原创 2024/5/21 11:57:20

虽然标题叫标准化，只不过是我自己的习惯，当一件事情变得流程标准化之后，开发程序就会飞快，开发评估工作总是搞个1~2天，实则前端后端一起开发，1个小时就可以搞定。
1 前端

const exportXls = async () => {var now = moment(new Date()).format('YYYYMMDDHHMMSS')let name = '商品收发明细表.xls'const res = await proxy.$api.invOrder.goodsRdDetail.export({...condForm.value})let data = res.data;let url = window.URL.createObjectURL(new Blob([data], ))let link = document.createElement('a')link.style.display = 'none'link.href = url;console.log(link);link.setAttribute('download', now + name)document.body.appendChild(link)link.click()document.body.removeChild(link)
}

请求的代码如下

public postOnlyFile = (url: string, data = {} , config: AxiosRequestConfig<any> = {}): Promise<any> =>axios({...this.baseConfig,headers:{...this.baseConfig.headers,'Content-Type': "application/json"},responseType:'blob',url,method: 'post',data,...config,})

2 后端
controller层基本就是复制粘贴，传参数给到service层而已。

    @PostMapping("export")@ApiOperation("导出商品收发明细表")public void export(@RequestBody PsiInvOrderReportCondDto condDto, HttpServletResponse response){//设置响应头response.setContentType("application/vnd.ms-excel");response.setCharacterEncoding("utf-8");//设置防止文件名中文乱码try {//设置防止文件名中文乱码String fileName = URLEncoder.encode("商品收发明细表", "utf-8");response.setHeader("Content-disposition", "attachment;filename=" + fileName + ".xlsx");//if (!CheckEmptyUtil.isEmpty(condDto.getBillDateRange())){condDto.setStartBillDate(condDto.getBillDateRange().get(0));condDto.setEndBillDate(condDto.getBillDateRange().get(1));}goodsRdDetailService.export(response.getOutputStream(),"xls/GoodsRdDetail.xls", condDto);} catch (Exception e) {log.error(e.getMessage(), e);}}

service层主要通过easyexcel填充数据

import com.alibaba.excel.EasyExcel;
import com.alibaba.excel.ExcelWriter;
import com.alibaba.excel.write.metadata.WriteSheet;
import com.alibaba.excel.write.metadata.fill.FillConfig;@Overridepublic void export(OutputStream outputStream, String pathName, PsiInvOrderReportCondDto condDto) {List<GoodsRdDetailListDto> goodsRdDetailListDtos = select(condDto);int line = 1;for (GoodsRdDetailListDto goodsRdDetailListDto:goodsRdDetailListDtos){goodsRdDetailListDto.setLine(String.valueOf(line++));goodsRdDetailListDto.setBillDateStr(DateUtil.formatDate(goodsRdDetailListDto.getBillDate()));BusinessTypeEnum businessTypeEnum = BusinessTypeEnum.getInvBusinessTypeEnum(goodsRdDetailListDto.getBusiType());goodsRdDetailListDto.setBusiType(businessTypeEnum.display());}org.springframework.core.io.Resource resource = new ClassPathResource(pathName);InputStream inputStream = null;String fileName = DateUtil.getDateRandom() + ".xls";File file = new File(TmpDic.url + File.separator + fileName);try {inputStream = resource.getInputStream();FileUtils.copyInputStreamToFile(inputStream, file);} catch (IOException e) {e.printStackTrace();}ExcelWriter excelWriter = EasyExcel.write(outputStream).withTemplate(file).build();FillConfig fillConfig = FillConfig.builder().forceNewRow(Boolean.TRUE).build();//WriteSheet sheet0 = EasyExcel.writerSheet(0,"单据明细（不合并表头）")//单元格
//                .registerWriteHandler(new CustomCellWriteHandler()).build();excelWriter.fill(goodsRdDetailListDtos, fillConfig, sheet0);//PsiAccountSet psiAccountSet = psiAccountSetService.getById(condDto.getAsId());GoodsRdDetailExcelHeaderDto excelHeaderDto = new GoodsRdDetailExcelHeaderDto();excelHeaderDto.setCompanyName(psiAccountSet.getName());excelHeaderDto.setStartBillDate(DateUtil.formatDate(condDto.getStartBillDate()));excelHeaderDto.setEndBillDate(DateUtil.formatDate(condDto.getEndBillDate()));excelWriter.fill(excelHeaderDto,sheet0);//excelWriter.finish();file.delete();}
