• springboot+easypoi模板导出Excel 动态表头+多表格(一个sheet)


    1.需求:将此页面的几个表格导出

    在这里插入图片描述
    其中表头中的仓库 集散地是是动态生成的。
    首先制作Excel模板:
    在这里插入图片描述
    代码:

    @Resource
    	private RedisService redisService;
    	@Override
    	public void assignModel(EventInfo info, HttpServletResponse response) {
    		AssginModelRes res=new AssginModelRes();
        	Object obj = redisService.getObj("modelExport-"+info.getId());
    		if (null == obj) {
    			throw new CustomException("找不到指定的事件!");
    		}
    		res = (AssginModelRes) obj;
        	try {
                // 获取workbook对象
                // 单sheet或多sheet 只需要更改此处即可
                Workbook workbook = exportAssignModelByTemplate(res) ;
                // 设置excel的文件名称
                String excelName = "资源分配模型" ;
                // 重置响应对象
                response.reset();
                // 当前日期,用于导出文件名称
                SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
                String dateStr = "["+excelName+"-"+sdf.format(new Date())+"]";
                // 指定下载的文件名--设置响应头
                response.setHeader("Content-Disposition", "attachment;filename=" +dateStr+".xls");
                response.setContentType("application/vnd.ms-excel;charset=UTF-8");
                response.setHeader("Pragma", "no-cache");
                response.setHeader("Cache-Control", "no-cache");
                response.setDateHeader("Expires", 0);
                // 写出数据输出流到页面
                OutputStream output = response.getOutputStream();
                BufferedOutputStream bufferedOutPut = new BufferedOutputStream(output);
                workbook.write(bufferedOutPut);
                bufferedOutPut.flush();
                bufferedOutPut.close();
                output.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
    
    	}
    private Workbook exportAssignModelByTemplate(AssginModelRes res) throws IOException {
    	        // 手动创建导出数据,需根据具体业务进行查询 
    	        // sheet1内容
    	        Map<String,Object> map = new HashMap<String, Object>() ;
    	        map.put("w1", res.getT1().getT1header().get(0)); 
    	        map.put("w2", res.getT1().getT1header().get(1)); 
    	        map.put("w3", res.getT1().getT1header().get(2));    
    	        map.put("resultList1",res.getT1().getData());
    	        for(int i=0;i<res.getT2().getT2header().size();i++) {
    	        	 map.put("p"+(i+1), res.getT2().getT2header().get(i));
    	        }
    	        map.put("resultList2",res.getT2().getData());
    	        map.put("resultList3",res.getT3().getData());
    	        map.put("resultList4_1",res.getT4().get(0).getData());
    	        map.put("resultList4_2",res.getT4().get(1).getData());
    	        map.put("resultList4_3",res.getT4().get(2).getData());
    	        // 设置导出配置
    	        // 获取导出excel指定模版
    			TemplateExportParams template = new TemplateExportParams("templates/model.xls", true);
    	        // 导出excel
    	        return ExcelExportUtil.exportExcel(template , map);
    	    }
    

    主要是在exportAssignModelByTemplate方法内创建map将数据动态地塞进模板里,数据实体类AssginModelRes 为
