1,首先,前端发送MultipartFile类型文件,后端接收

2,分别创建多个ImportParams对象(easypoi),对应工作蒲

 注意:pom中 要有相对应的配置

<!-- easypoi -->
        <dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-base</artifactId>
            <version>3.2.0</version>
        </dependency>
        <dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-web</artifactId>
            <version>3.2.0</version>
        </dependency>

startSheetIndex 开始读取的sheet位置,默认为0

startRows 字段真正值和列标题之间的距离 默认0

titleRows 表格标题行数,默认0

            ImportParams sheet1 = new ImportParams();
            sheet1.setStartSheetIndex(0);
            sheet1.setStartRows(0);
            sheet1.setTitleRows(0);

            ImportParams sheet2 = new ImportParams();
            sheet2.setStartSheetIndex(1);
            sheet2.setStartRows(0);
            sheet2.setTitleRows(0);

            ImportParams sheet3 = new ImportParams();
            sheet3.setStartSheetIndex(2);
            sheet3.setStartRows(0);
            sheet3.setTitleRows(1);

            ImportParams sheet4 = new ImportParams();
            sheet4.setStartSheetIndex(3);
            sheet4.setStartRows(0);
            sheet4.setTitleRows(1);

3,使用easypoi自带的工具类ExcelImportUtil,将数据读取到集合中

            List<MaterialLibPO> materialList = ExcelImportUtil.importExcel(excel.getInputStream(), MaterialLibPO.class, sheet1);
            List<BigMaterialPO> largeList = ExcelImportUtil.importExcel(excel.getInputStream(), BigMaterialPO.class, sheet2);
            List<RoutineMaterialPO> conventionalList = ExcelImportUtil.importExcel(excel.getInputStream(), RoutineMaterialPO.class, sheet3);
            List<ToolLibPO> toolLibList = ExcelImportUtil.importExcel(excel.getInputStream(), ToolLibPO.class, sheet4);

　　注意:对应的实体类要加 @Excel(name = "对应名称") 这里以MaterialLibPO为实例

@Data
@AllArgsConstructor
@NoArgsConstructor
public class MaterialLibPO implements Serializable {
    /**
     * 唯一标识
     */
    @Excel(name = "抢修物资库UUID")
    private String id;

    /**
     * 地市id
     */

    private String ssdsid;

    /**
     * 区县id
     */
    private String ssqxid;

    /**
     * 供电单位id
     */

    private String ssgddwid;

    /**
     * 抢修站id
     */
    @Excel(name = "抢修站ID")
    private String qxzid;

    /**
     * 物资库名称
     */
    @Excel(name = "物资库名称（抢修站名+物资库）")
    private String wzkmc;

    /**
     * 移动库个数
     */
    @Excel(name = "移动库个数（四轮抢修车辆数）")
    private String ydkgs;

    /**
     * 库存状态
     */
    @Excel(name = "库存状态")
    private String kczt;

    /**
     * 经度
     */
    private String jd;

    /**
     * 纬度
     */
    private String wd;
    /**
     * 所属供电单位名称
     */
    @Excel(name = "供电单位（市县公司）")
    private String ssgddwmc;
    /**
     * 所属地市名称
     */
    @Excel(name = "地市")
    private String ssdsmc;
    /**
     * 抢修站名称
     */
    @Excel(name = "抢修站名称（附表抢修站标准名称）")
    private String qxzmc;

    private static final long serialVersionUID = 1L;
}

4,获取到list集合后,就可以对数据进行处理或者存储了
