使用Hutool解析excel导入数据

Hutool解析excel导入数据

本人是 hutool 的狂热粉丝~~~

话不多说，上代码！！！
hutool依赖，这里暂不赘述，，官网找即可。

	/**
	 * 导入样本事故  controller
	 * @param file
	 */
	@PostMapping("/importTemplate")
	@ApiOperation(value = "导入样本事故")
	public R importTemplate(MultipartFile file) {
		return new R(causeModelSampleService.importTemplate(file));
	}

//service业务代码
@Override
	public R importTemplate(MultipartFile file) {
		InputStream inputStream = null;
		try {
			inputStream = file.getInputStream();
		}catch (Exception e){
			return new R(e.getMessage());
		}
		ExcelReader reader = ExcelUtil.getReader(inputStream, 0); //指定输入流和sheet
		// 读取第二行到最后一行数据
		List<List<Object>> read = reader.read(1, reader.getRowCount());
		List<CauseModelSample> samples = new ArrayList<>();
		for (List<Object> objects : read) {
			CauseModelSample causeModelSample = new CauseModelSample();
			Object sampleNo = objects.get(0);//读取某行第一列数据
			Object sampleName = objects.get(1); //读取某行第二列数据
			Object sampleLevel = objects.get(2); //读取某行第三列数据
			Object accidentId = objects.get(3); //读取某行第四列数据
			Object industryTypeId = objects.get(4); //读取某行第五列数据
			Object corpScale = objects.get(5); //读取某行第六列数据
			Object address = objects.get(6); //读取某行第七列数据
			causeModelSample.setSampleNo(sampleNo.toString()); //样本编号
			causeModelSample.setSampleName(sampleName.toString()); //样本名称
			causeModelSample.setSampleLevel(sampleLevel.toString()); //样本事故级别
			causeModelSample.setBelongAccidentId(Long.parseLong(accidentId.toString()));
			causeModelSample.setBelongIndustryTypeId(Long.parseLong(industryTypeId.toString()));
			causeModelSample.setCorpScale(corpScale.toString()); //企业规模
			causeModelSample.setAddress(address.toString()); //详细地址
			causeModelSample.setIsSample(SemConstants.PS_NO_SAMPLE); //导入的 不是样本N
			causeModelSample.setCauseNetworkStatus(CauseNetworkEnum.TEMPORARY_STORAGE.value); //导入为暂存状态
			samples.add(causeModelSample);
		}
		return new R(causeModelSampleManager.saveBatch(samples));
