JAVA实现easyExcel模版导出

easyExcel文档

模板注意：

• 用 {} 来表示你要用的变量 ，如果本来就有"{“,”}" ，特殊字符用"{“,”}"代替
• {} 代表普通变量
• {.}代表是list的变量

添加pom依赖

<dependency>
    <groupId>com.alibabagroupId>
    <artifactId>easyexcelartifactId>
    <version>2.2.6version>
dependency>


<dependency>
    <groupId>cn.hutoolgroupId>

第一种：简单模版导出

实体类

package com.example.mybatismysql8demo.excel;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.experimental.Accessors;

import java.io.Serializable;
import java.math.BigDecimal;

@NoArgsConstructor
@AllArgsConstructor
@Accessors(chain = true)
@Data
public class TemplateGoodsExcel implements Serializable {
   

    private String goodsName;

    private Integer num;

    private BigDecimal price;

    public TemplateGoodsExcel(String goodsName, BigDecimal price, Integer num) {
   
        this.goodsName = goodsName;
        this.price = price;
        this.num = num;
    }

}

导出模版
