引入Easypoi的maven坐标，我使用的是4.0.0版本

   		<dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-spring-boot-starter</artifactId>
            <version>4.0.0</version>
        </dependency>

先看下Excel模板

实体类

package com.lee.entity.excel;

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

    private int rowNum;

    /**

    private String errorMsg;

    @Excel(name = "花纹深度(mm)", fixedIndex = 5)
    private Double figureDepth;

    @Excel(name = "胎面宽(mm)", fixedIndex = 6)
    private Double tireWidth;

    @Excel(name = "外胎重量(kg)", fixedIndex = 7)
    private Double tireWeight;


    @Excel(name = "市场批发价格", fixedIndex = 8)

    private String remark;

    @Excel(name = "车型", fixedIndex = 20)
    private String carType;

    @Excel(name = "马力(匹)", fixedIndex = 21)
    private Double horsepower;
    /**

    @Excel(name = "路况", fixedIndex = 22)
    private String roadCondition;
    /**

     */
    @Excel(name = "最小", fixedIndex = 23)
    private Double loadWeightLeft;
    /**
     * 最高载重量
     */
    @Excel(name = "最大", fixedIndex = 24)
    private Double loadWeightRight;
    /**

    @Excel(name = "最小", fixedIndex = 25)
    private Double speedLeft;
    /**

    @Excel(name = "最大", fixedIndex = 26)
    private Double speedRight;
    /**

    @Excel(name = "最小", fixedIndex = 27)
    private Double runDistanceLeft;
    /**
     * 最高运输距离
     */
    @Excel(name = "最大", fixedIndex = 28)
    private Double runDistanceRight;
}

我看网上对于复杂表头的导入要使用groupName，我没有使用也没有什么问题，应该是后续版本升级了，去掉了繁琐操作，但是fixedIndex 是一定要写对的，否则映射不上数据。

导入的代码

 @ApiOperation("EasyPoi导入数据测试")
    @PostMapping("/importCompetitorData")
    public Boolean importCompetitorData(@RequestParam("file") MultipartFile file) throws Exception {
        ImportParams params = new ImportParams();
        // 表头设置为3行
        params.setHeadRows(3);
        // 标题行设置为0行，默认是0，可以不设置
        params.setTitleRows(1);
        // 是否需要校验上传的Excel,默认为false
        params.setNeedVerify(true);
        ExcelImportResult<CompetitorInputEntity> result = ExcelImportUtil.importExcelMore(file.getInputStream(),
                CompetitorInputEntity.class, params);
        System.out.println("是否校验失败: " + result.isVerfiyFail());
        System.out.println("校验失败的集合:" + JSONObject.toJSONString(result.getFailList()));
        System.out.println("校验通过的集合:" + JSONObject.toJSONString(result.getList()));
        for (CompetitorInputEntity entity : result.getFailList()) {
            String msg = "第" + (entity.getRowNum() + 1) + "行的错误是：" + entity.getErrorMsg();
            System.out.println(msg);
        }
        return true;

    }

TitleRows 和 HeadRows 如何设置？

TitleRows： 代表标题行，可以理解忽略的行数，在导入的过程中忽略掉。
HeadRows：代表表头，默认是1，但是对比我这次的导入的Excel，我设置的表头是3。
还不懂？来幅图，是不是瞬间发出，噢~~

测试下

第6行厂家名称我没填，验证下检验怎么样，看样子没问题。
