1.定义工具类
package com.pagi.iiwpp.est.cio.fncreport.common;
import cn.afterturn.easypoi.excel.ExcelExportUtil;
import cn.afterturn.easypoi.excel.entity.TemplateExportParams;
import lombok.extern.slf4j.Slf4j;
import org.apache.poi.ss.usermodel.Workbook;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import javax.servlet.http.HttpServletResponse;
import java.io.BufferedOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.net.URLEncoder;
import java.util.Map;
/**

@Slf4j
public class ExcelUtils {
public static void importTemplateSheets(Map<String, Object> dataMap, String path, String fileName) throws IOException {
ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
assert servletRequestAttributes != null;
HttpServletResponse response = servletRequestAttributes.getResponse();
// 重置响应对象
assert response != null;
response.reset();
// 指定下载的文件名--设置响应头
response.setHeader("Content-Disposition", "attachment;filename=" + new String(fileName.getBytes("GBK"), "ISO8859-1"));
response.setContentType("application/vnd.ms-excel;charset=UTF-8");
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
TemplateExportParams params = new TemplateExportParams(path, true);
try (Workbook workbook = ExcelExportUtil.exportExcel(params, dataMap);
OutputStream outputStream = response.getOutputStream();
BufferedOutputStream bufferedOutPut = new BufferedOutputStream(outputStream)
) {
workbook.write(bufferedOutPut);
log.info("文件【" + fileName + "】导出成功！");
} catch (Exception e) {
log.error("【文件操作失败】：" + e.getMessage());
response.setHeader("Content-Disposition", String.format("attachment; filename=%s",
URLEncoder.encode("导出失败.xlsx", "utf-8")));
}finally {
response.flushBuffer();
}
}
}
2.controller 中调用， resultMap 是sql查询数据得结果集
@GetMapping("/middleData/export")
public void exportFncT1ReportMiddleData(@RequestParam(value = "theDate") @DateTimeFormat(pattern="yyyy-MM-dd") Date theDate) {
try {
Map<String, Object> resultMap = fncT1ReportService.selectNCMST1ExportData(theDate);
String fileName = "不动产金融产品上报_" + StringDateUtil.dateToString(theDate, 1) + ".xlsx";
ExcelUtils.importTemplateSheets(resultMap, "template/FNC_T1_CIO_DET.xlsx", fileName);
} catch (Exception e) {
e.printStackTrace();
}
}
2.数据来源： 假设excel 中有两个sheet :基础信息表 和 基础信息表
@Override
public Map<String, Object> selectNCMST1ExportData(Date theDate) throws Exception {
Map<String, Object> resultMap = Maps.newHashMap();
if (theDate == null) {
throw new Exception("请求处理参数为空！");
}
Map<String, Object> paramMap = Maps.newHashMapWithExpectedSize(11);
paramMap.put("theDate", StringDateUtil.dateToString(theDate, 3));
// 基础信息表
StringBuilder sb = new StringBuilder("本次导出金融产品数据统计如下：");
List<IfT1Debt> ifT1DebtList = ifT1DebtService.selectNCMST1DebtInfoList(paramMap);
resultMap.put("ifT1DebtList", ifT1DebtList); //ifT1DebtList 这个key 要写如excel 中去
sb.append("【项目-债权】基础信息表").append(ifT1DebtList.size()).append("条，");
// by liulewei187
//险资明细
List<IfInsuranceDetails> ifInsuranceDetailList = ifInsuranceDetailsService.selectNCMST1InsuranceDetailsList(paramMap);
resultMap.put("ifInsuranceDetailList", ifInsuranceDetailList);
sb.append("【项目-债权】基础信息表").append(ifInsuranceDetailList.size()).append("条，");
log.info(sb.toString());
return resultMap;
}
Excel 模板中加上一行 属性定义： 根据你得表字段定义

4. 使用postman 测试时，send 下拉框 选择 send and download 可以保存导出得excel
