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<String, Object> params,ModelMap model,HttpServletRequest request, HttpServletResponse response){
            List<ProductEntity> list=new ArrayList<ProductEntity>();//
            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<String> lists =(List<String>) params.get("selected");
                 List<String> old = new ArrayList<String>();
                 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

package com.alpha.modules.product.entity;

import java.io.Serializable;
import java.util.Date;
import java.util.List;
import java.util.Map;

import org.hibernate.validator.constraints.NotBlank;

import cn.afterturn.easypoi.excel.annotation.Excel;

/**

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

    // ID
    @NotBlank(message = "参数值不能为空")
    private Long id;

    // 产品名称
    @Excel(name = "产品名称", orderNum = "2", width = 20)
    private String name;

    // 产品编号
    @Excel(name = "产品编号", orderNum = "2", width = 20)
    private String code;

    // 样品类别代码
    private String typeCode;
    private String typeName;

    // 产品分类代码
    private Integer categoryId;
    @Excel(name = "产品类别", orderNum = "3", width = 10)
    private String categoryName;

    // 产品分类备注
    private String categoryNote;

    // 主题代码
    private String themeCode;
    @Excel(name = "产品主题", orderNum = "4", width = 10)
    private String themeName;

    // 供应商代码
    @Excel(name = "工厂代码", orderNum = "6", width = 10)
    private String factoryCode;
    // 供应商名称
    @Excel(name = "工厂名称", orderNum = "5", width = 30)
    private String factoryName;

    // 产品报价
    @Excel(name = "工厂报价", orderNum = "7", width = 10)
    private Double price;

    // 报价币种
    @Excel(name = "币种", orderNum = "8", width = 10)
    private String currency;

    // 单位
    @Excel(name = "单位", orderNum = "9", width = 10)
    private String unit;

    // 开发人用户名
    @Excel(name = "开发人", orderNum = "10", width = 15)
    private String developUser;

    // 设计人用户名
    @Excel(name = "设计人", orderNum = "11", width = 15)
    private String designUser;

    // 产品材质
    @Excel(name = "产品材质", orderNum = "12", width = 15)
    private String material;

    // 工厂货号
    @Excel(name = "工厂货号", orderNum = "13", width = 15)
    private String factoryNo;

    // 产品描述
    @Excel(name = "产品描述", orderNum = "14", width = 35)
    private String descNote;

    // 图片加密：0不加密，1加密
    private Integer encrypt;

    // 上传时间
    @Excel(name = "录入时间", orderNum = "15", width = 20,exportFormat="yyyy-MM-dd")
    private Date ctime;

    // 图片url
    @Excel(name = "产品图片", orderNum = "1", imageType = 1, type = 2, width = 35, height = 49)
    private String picUrl;

    // 上传操作员
    @Excel(name = "录入人员", orderNum = "16", width = 15)
    private String cuser;

    // 唛头
    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<Map<String, Object>> suitList;

    // 产品类型:0主料,1辅料
    private Integer proType;
    
    private String customerCode;
    
    private String topCategory;
    
    private int serialNum;//序列号
    
    private int filialeId;
}

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<String, Object> param,
            HttpServletRequest request, HttpServletResponse response) {

        ExportParams params = new ExportParams(null, "装箱单报表", ExcelType.XSSF);
        List<PackingReportCostEntity> 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。。。。
