本文章主要是记录自己的一些心得和之前写过的一些功能，无意进行技术辩论，大神们留下足迹就好。

1. 根据模板导出多sheet表格数据

1. 先上代码

 @ApiOperation(value = "导出多个sheet数据接口")@GetMapping("/exportMulData")public void exportMulData(OaPurchaseContract oaPurchaseContract, HttpServletResponse response) throws Exception {//这里是你需要往里面添加数据的模板路径，放在templates下面即可try {//excel模板(其实这里使用缓冲流getResource或者getResourceAsStream()就行)String template = createNewFileByTemplate("/template/合同备案数据导出模板.xlsx");File file = ResourceUtils.getFile(template);try (FileInputStream fileInputStream = new FileInputStream(file); ByteArrayOutputStream bos = new ByteArrayOutputStream()) {//填充到sheet的数据List list1 = new ArrayList<Object>();List list22 = new ArrayList<Object>();// 获取需要导出的数据List<OaPurchaseContractVO> list = oaPurchaseContractService.selectContractFilingExportInfo(oaPurchaseContract);if(CollectionUtils.isNotEmpty(list)){// 格式化日期list= list.stream().map(oaPurchaseContractVO-> {// 这里需要对导出的日期进行转换 不然会出现格式错误oaPurchaseContractVO.setWriteDate(this.formatDate(oaPurchaseContractVO.getWriteDate()));oaPurchaseContractVO.setStartDate(this.formatDate(oaPurchaseContractVO.getStartDate()));oaPurchaseContractVO.setEndDate(this.formatDate(oaPurchaseContractVO.getEndDate()));return oaPurchaseContractVO;}).collect(Collectors.toList());}List<Map<String, Object>> maps = BeanUtil.objectList2ListMap(list);list1 = maps;// 合同结算数据List<OaPurchaseContractVOTwo> list2 = oaPurchaseContractService.selectContractEndCountExportInfo(oaPurchaseContract);List<Map<String, Object>> maps2 = BeanUtil.objectList2ListMap(list2);list22 = maps2;//原模板只有一个sheet，通过poi复制出需要的sheet个数的模板XSSFWorkbook workbook = new XSSFWorkbook(fileInputStream);for (int i = 0; i < 1; i++) {//复制模板，得到第i个sheetworkbook.cloneSheet(0, "合同备案数据(必填)");workbook.cloneSheet(1, "合同结算数据(必填)");}// 最关键的操作就是这个 （将前面的sheet模板数据移除）workbook.removeSheetAt(0);workbook.removeSheetAt(0);//写到流里workbook.write(bos);byte[] bArray = bos.toByteArray();InputStream is = new ByteArrayInputStream(bArray);//输出文件路径String fileName = "采购合同" + System.currentTimeMillis() + ".xlsx";response.reset();// 设置文件对应后缀的ContentTyperesponse.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");// 返回的是流的形式response.setContentType("application/octet-stream; charset=utf-8");response.setHeader("Location", fileName);response.setHeader("Cache-Control", "max-age=0");// 这句的作用是会打开用户那边下载文件时的那个保存位置的框，如果文件名中有中文，建议编下码response.setHeader("Content-disposition", "attachment; filename=" + URLEncoder.encode(fileName, "UTF8"));ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream()).withTemplate(is).build();for (int i = 0; i < 1; i++) {WriteSheet writeSheet = EasyExcel.writerSheet("合同备案数据(必填)").build();excelWriter.fill(list1, writeSheet);WriteSheet writeSheet1 = EasyExcel.writerSheet("合同结算数据(必填)").build();excelWriter.fill(list22, writeSheet1);}// 关闭流excelWriter.finish();} catch (IOException e) {e.printStackTrace();}} catch (Exception e) {e.printStackTrace();}}/*** 格式化日期得方法* @param writeDate* @return*/private String formatDate(String writeDate) {return writeDate.replace("-","");}private String createNewFileByTemplate(String templateFilePath){// String templateFilePath = "/template/基金Call款通知书.docx";String originalFileName = IdGen.uuid() + "." + "xlsx";String originalFilePath = RuoYiConfig.getProfile() + File.separator + "temp";String fullFilePath = originalFilePath + File.separator + originalFileName;try(InputStream inputStream = this.getClass().getResourceAsStream(templateFilePath)){FileUtil.writeFromStream(inputStream, fullFilePath);}catch (IOException ioe){LogUtils.error("生成模板文件时异常!", ioe);}return fullFilePath;}

2. 模板展示

3. 数据构造

1.实体类创建

@ExcelProperty注解必须要加上，不然无法读取出来

@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class OaPurchaseContractVO implements Serializable {@ExcelProperty("合同号")private String contractNumber;@ExcelProperty("备案公司")private String companyName;@ExcelProperty("签订部门代码")private String departmentCode;@ExcelProperty("签订部门名称")private String deptName;@ExcelProperty("签约客商代码")private String custerCode;@ExcelProperty("签约客商名称")private String custerName;@ExcelProperty("签订人工号")private String contractKey;@ExcelProperty("签订人名称")private String writerName;@ExcelProperty("合同起草人工号")private String startorKey;@ExcelProperty("合同起草人名称")private String startContractName;@ExcelProperty("合同末级审核人工号")private String endorKey;@ExcelProperty("合同末级审核人姓名")private String endReviewKey;@ExcelProperty("合同名称")private String contractName;@ExcelProperty("合同标的")private String contractBd;@ExcelProperty("合同大类")private String bigClass;@ExcelProperty("合同小类")private String smallClass;@JsonFormat(locale="zh", timezone="GMT+8", pattern="yyyy-MM-dd")@ExcelProperty(value = "合同签订日期")private String writeDate;@JsonFormat(locale="zh", timezone="GMT+8", pattern="yyyy-MM-dd")@ExcelProperty(value ="合同生效日期")private String startDate;@JsonFormat(locale="zh", timezone="GMT+8", pattern="yyyy-MM-dd")@ExcelProperty(value ="合同到期日")private String endDate;@ExcelProperty("是否多次结算")private String moreJs;@ExcelProperty("是否标准格式文本")private String sfBzText;@ExcelProperty("是否经过法审")private String wheatherFs;@ExcelProperty("是否阳光采购")private String sfYgCg;@ExcelProperty("未阳光采购理由")private String noYgCg;@ExcelProperty("未阳光采购其他理由")private String other;@ExcelProperty("是否招投标")private String sfZtb;@ExcelProperty("是否集团外贸易")private String sfJtw;@ExcelProperty("签约客商代码（多方）")private String one;@ExcelProperty("签约客商名称")private String oneName;@ExcelProperty("签约客商代码（多方）")private String two;@ExcelProperty("签约客商名称")private String twoName;@ExcelProperty("签约客商代码（多方）")private String three;@ExcelProperty("签约客商名称")private String threeName;@ExcelProperty("签约客商代码（多方）")private String four;@ExcelProperty("签约客商名称")private String fourName;@ExcelProperty("签约客商代码（多方）")private String five;@ExcelProperty("签约客商名称")private String fiveName;@ExcelProperty("签约客商代码（多方）")private String six;@ExcelProperty("签约客商名称")private String sixName;}

2. sql数据构造(主要是需要把结果集别名映射到对应的实体类上)

上面主要是针对有模板的情况下进行多sheet导出

下面介绍无模块，手动构造模块进行多sheet导出（适合字段少的）

2. 无模板多sheet导出

1. code部分

// 方式一(自定义导出,无模板,字段多不建议)@ApiOperation(value="导出多个sheet数据接口")@GetMapping("/exportMulData")public void exportMulData(OaPurchaseContract oaPurchaseContract,HttpServletResponse response) throws Exception {oaPurchaseContractService.exportMulData(oaPurchaseContract,response);}

导出的案例很多，但是当自己在用的时候还是自己熟悉的代码比较舒服。
