easypoi的简单导出 数据map导出
官方说明文档
http://easypoi.mydoc.io/
需要渲染的模版
语法
循环开始 {{$fe:maplist t.ho
循环中间参数 t.po
换行]]
循环结尾t.amount}}
统计循环数量{{sum:(t.amount)}}
单独参数{{totalQuantity}}
常见命令
• 空格分割
• 三目运算 {{test ? obj:obj2}} ps:{{QcNum == 0?image:null}}
• n: 表示 这个cell是数值类型 {{n:}} ps:{{n:packingNum}}
• le: 代表长度{{le:()}} 在if/else 运用{{le:() > 8 ? obj1 : obj2}}
• fd: 格式化时间 {{fd:(obj;yyyy-MM-dd)}}
• fn: 格式化数字 {{fn:(obj;###.00)}}
• fe: 遍历数据,创建row
• !fe: 遍历数据不创建row
• $fe: 下移插入,把当前行,下面的行全部下移.size()行,然后插入
• #fe: 横向遍历
• v_fe: 横向遍历值
• !if: 删除当前列 {{!if:(test)}}
• 单引号表示常量值 '' 比如'1' 那么输出的就是 1
• &NULL& 空格
• ]] 换行符 多行遍历导出
• sum: 统计数据 {{sum:(t.amount)}}

过滤的应用场景
@RequestMapping("exportExcel")
@SuppressWarnings("unchecked")
@RequiresPermissions("business:product:exportExcel")
public R exportExcel(@RequestBody Map params,ModelMap model,HttpServletRequest request, HttpServletResponse response){
List list=new ArrayList();//
ExportParams param = new ExportParams("产品信息", "产品信息",ExcelType.XSSF);
if(params.get("ids")!=null){
list=productService.queryListByIds(params.get("ids"));
}else{
list=productService.queryListTwoThousand(params);
}
if(params.get("selected")!=null){
String[] s=params.get("selected").toString().split(",");//前端获取选中的栏目
List lists =(List) params.get("selected");
List old = new ArrayList();
ProductEntity entity=new ProductEntity();
for (Field field : entity.getClass().getDeclaredFields()) {//去掉选中的栏目
if(!lists.contains(field.getName())){
old.add(field.getName());
}
}
s= old.toArray(new String[1]);//list转数组
param.setExclusions(s);//过滤没有选中的栏目导出
}
Workbook workbook = ExcelExportUtil.exportExcel(param, ProductEntity.class,list);
ByteArrayOutputStream fos;
String url="";
try {
fos = new ByteArrayOutputStream();
workbook.write(fos);
url=OSSFactory.build().upload(fos.toByteArray(), OSSConfig.getALI_TEMP()+"excel/product_excel"+System.currentTimeMillis()+".xlsx");
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
if(url.length()>0){
return R.ok().put("url", url).put("msg", "生成成功");
}else{
return R.error().put("msg", "生成失败");
}
}
这个是文件上传阿里云的 顺便过滤选中自己想导出不同栏目的,接下来看看实体类

public class ProductEntity implements Serializable {
private static final long serialVersionUID = 1L;
// ID

private String mark;
// 状态:0禁用,1开启 默认:0
private Integer state;
// 图片样式
private String picStyle;
private Integer isSuit;
private String suitCode;
private String fingerprint;// 指纹信息
private List
用注解 包括日期格式 数字替换文字等
@Excel(name = "录入时间", orderNum = "15", width = 20,exportFormat="yyyy-MM-dd")
//时间格式
@Excel(name = "产品图片", orderNum = "1", imageType = 1, type = 2, width = 35, height = 49)
//图片
//数字替换成文字
@Excel(name = "发票状态", orderNum = "1",replace = { "未推送_0", "已推送_1" }, width = 20)
map封装导出比较类似
实体类导出excel 简单导出
@RequestMapping("/exportPackingReportExcel")
public void exportPackingReportExcel(ModelMap model, @RequestParam Map param,
HttpServletRequest request, HttpServletResponse response) {
ExportParams params = new ExportParams(null, "装箱单报表", ExcelType.XSSF);
List dataList =packing.exportPackingReportExcel(param);
model.put(NormalExcelConstants.DATA_LIST, dataList);
model.put(BigExcelConstants.CLASS, PackingReportCostEntity.class);
model.put(BigExcelConstants.PARAMS, params);
model.put(MapExcelConstants.FILE_NAME, "装箱单报表");
PoiViewUtil.render(model, request, response, NormalExcelConstants.EASYPOI_EXCEL_VIEW);
}
js文件
//参数等 这个是最简单的导出
window.location.href="/"+T.moduleName+"/packingReport/exportPackingReportExcel?"
导出复杂的word待续。。。。
