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sheet
workbook.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ContentType
response.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) {

}
}

}

}
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

3. 效果演示
结言
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。
