使用EasyExcel导出表格

前端代码

/**
 *导出excel  用过layui的都看的懂
 */
function exports() {
    layer.confirm('确定导出所有策略的信息？', {
        btn: ['确定', '取消']
    }, function(index){
        //按钮【按钮一】的回调
        location.href=prefix + '/exports';
        layer.close(index);
    }, function(index){
        //按钮【按钮二】的回调
    });
}

后端代码

@ExcelProperty是代表导出后这个属性对应的列名是什么  以及位置

package com.bootdo.cpm.domain;

import com.alibaba.excel.annotation.ExcelProperty;
import com.alibaba.excel.metadata.BaseRowModel;

import java.io.Serializable;

import javax.persistence.GeneratedValue;
import javax.persistence.Id;

import lombok.Data;


/**
 * cpm策略表

 * 
 * @author hw
 * @email [email protected]
 * @date 2019-03-26 11:26:41
 */
@Data
public class CpmStrategyDO extends BaseRowModel implements Serializable {
	private static final long serialVersionUID = 15353L;
	
	//标识id
	@Id
	@GeneratedValue(generator = "JDBC")
	@ExcelProperty(value = "策略id",index = 0)
	private Integer cpmId;
	//名称标题
	@ExcelProperty(value = "名称标题",index = 1)
	private String cpmTitle;
	//广告链接
	@ExcelProperty(value = "广告链接",index = 2)
	private String cpmUrl;
	//持续范围时间开始日
	@ExcelProperty(value = "持续范围时间开始日",index = 3)
	private Object cpmBegindate;
	//持续范围时间结束日
	@ExcelProperty(value = "持续范围时间结束日",index =4)
	private Object cpmEnddate;
	//单个用户接触的数量
	@ExcelProperty(value = "单个用户接触的数量",index =5)
	private Integer userNum;
	//投放数量(千)
	@ExcelProperty(value = "投放数量",index =6)
	private Object cpmNum;
	//当前总次数
	@ExcelProperty(value = "当前总次数",index =7)
	private Integer currentNum;
	//cpm描述
	@ExcelProperty(value = "描述",index =8)
	private String cpmDetailed;
	//cpm运行开始时间段(比如两点到四点的两点)
	@ExcelProperty(value = "运行开始时间段",index =9)
	private Object runBegindate;
	//cpm运行结束时间段(比如两点到四点的四点)
	@ExcelProperty(value = "运行结束时间段",index =10)
	private Object runEnddate;
	//拼接数据(用于返回给apk)
	private String jsondata;
	//优先级
	private Integer priority;
	//创建时间
	private Object createDate;
	//状态 0没运行,1运行
	private Integer status;
	//倒计时策略id
	private Integer timeId;
}

Controller代码

@RequestMapping("/exports")
    @ResponseBody
    @RequiresPermissions("cpm:cpmStrategy:cpmUser")
    public void exports(HttpServletRequest request, HttpServletResponse response) {
        //需要导出的数据
        List<CpmStrategyDO> list = cpmStrategyService.list(null);
        try {
            ServletOutputStream out = response.getOutputStream();
            ExcelWriter writer = new ExcelWriter(out, ExcelTypeEnum.XLSX, true);

            String fileName = new String("CPM策略信息表格"
                    .getBytes("utf-8"), "iso8859-1");
            Sheet sheet1 = new Sheet(1, 0, CpmStrategyDO.class);
            sheet1.setSheetName("sheet1");

            response.setHeader("Content-disposition", "attachment;filename="+fileName+".xlsx");
            response.setContentType("multipart/form-data");
            response.setCharacterEncoding("utf-8");
            writer.write(list, sheet1);
            writer.finish();
            out.flush();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
