版权声明：本文为博主原创文章，转载记得声明出处。 https://blog.csdn.net/qq_40100817/article/details/82799036

首先引入jar包的maven依赖：

                    
		
			org.apache.poi
			poi
			${poi.version}
		
		
			org.apache.poi
			poi-ooxml
			${poi.version}
		
		
			org.apache.poi
			poi-ooxml-schemas
			${poi.version}
		

1.前端显示

//"#btnExport"导出按钮的id  #searchForm from表单的id
$("#btnExport").click(function(){
   if(confirm("确认要导出样品数据吗？")==true){ 
			 		                                                                                                                                                                            
      $("#searchForm").submit();
		
}
});

2.导出的编写

        	HSSFCell cell = null;
        	//设置表头的列宽
        	for (int i = 0; i < title.length; i++) {
        		sheet.setColumnWidth(i, 6000);
			}
        	// 第三步，在sheet中添加表头第0行,注意老版本poi对Excel的行数列数有限制

            for(int i=0;i keeSpecimenList = map.get(keeSeries.getId());
    			if (!keeSpecimenList.isEmpty()) {
    				 for(int i=0;i

3.控制层调用

	//样品导出
	@RequiresPermissions("specimen:keeSpecimen:view")
    @RequestMapping(value = "export", method=RequestMethod.POST)
    public void exportFile(KeeSpecimen keeSpecimen, HttpServletRequest request, HttpServletResponse response, RedirectAttributes redirectAttributes) {
			List keeSpecimenList= keeSpecimenService.findList(keeSpecimen);
			// 生成Excel
			//excel标题
			 String[] title={"编码","二维码","分类归属","中文名称","英文名称","主图","浏览数","下单数"};
			 //excel名称
			 String fileName = "样品数据.xls";
			//sheet名 
			 String sheetName = "样品信息";
			 
			HSSFWorkbook wb = ExcelUtil.getHSSFWorkbook(sheetName, title, keeSpecimenList,null);
			//响应到客户端
			try {
				this.setResponseHeader(response, fileName);
				OutputStream os = response.getOutputStream();
				wb.write(os);
				os.flush();os.close();
			} catch (Exception e) {
				e.printStackTrace();
				System.err.println(e.getMessage());
			}
    }
	
//主推导出
	@RequiresPermissions("specimen:keeSeries:view")
    @RequestMapping(value = "export", method=RequestMethod.POST)
    public void exportFile(KeeSeries keeSeries, HttpServletRequest request, HttpServletResponse response, RedirectAttributes redirectAttributes) {
			//获取所有的主推
			List keeSeriesList= keeSeriesService.findList(keeSeries);
			Map> map = new HashMap(); 
			//查询主推系列下面的样品
			for (KeeSeries keeSeries2 : keeSeriesList) {
				List keeSpecimenList = new ArrayList();
				KeeSeriesDetails keeSeriesDetails = new KeeSeriesDetails();
				keeSeriesDetails.setSeriesid(keeSeries2.getId());
				List keeSeriesDetailsList = keeSeriesDetailsDao.findList(keeSeriesDetails);
				if (!keeSeriesDetailsList.isEmpty()) {
					for (KeeSeriesDetails keeSeriesDetails2 : keeSeriesDetailsList) {
						keeSpecimenList.add(keeSpecimenService.get(keeSeriesDetails2.getSpecimenid()));
					}
				}
				map.put(keeSeries2.getId(), keeSpecimenList);
			}
			
			// 生成Excel
			//excel标题
			 String[] title={"中文名称","英文名称","中文图片","英文图片","浏览量","下单量","发布状态"};
			 String[] titleSpecimen={"编码","二维码","分类归属","中文名称","英文名称","主图","下单数/浏览数"};
			 //excel名称
			 String fileName = "主推系列数据.xls";
			 
			HSSFWorkbook wb = ExcelUtil.getSeriesHSSFWorkbook( title, titleSpecimen, keeSeriesList,map,null);
			//响应到客户端
			try {
				this.setResponseHeader(response, fileName);
				OutputStream os = response.getOutputStream();
				wb.write(os);
				os.flush();os.close();
			} catch (Exception e) {
				e.printStackTrace();
				System.err.println(e.getMessage());
			}
    }

	 //发送响应流方法
    public void setResponseHeader(HttpServletResponse response, String fileName) {
        try {
            try {
                fileName = new String(fileName.getBytes(),"ISO8859-1");
            } catch (UnsupportedEncodingException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            response.setContentType("application/octet-stream;charset=ISO8859-1");
            response.setHeader("Content-Disposition", "attachment;filename="+ fileName);
            response.addHeader("Pargam", "no-cache");
            response.addHeader("Cache-Control", "no-cache");
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

4.导出效果：
