excel导出标准化

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

ts 复制代码

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

ts 复制代码

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。

java 复制代码

    @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

java 复制代码

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;
    @Override
    public 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();
    }

3 excel模板

定义excel模板，就是上面的xls/GoodsRdDetail.xls
