Easypoi导入提示错误行号和错误描述,拿来即用

实现效果

{
    "success": false,
    "code": "400",
    "msg": "请求参数有误",
    "errorMsg": "第2行，参考价格不能为空, 参考价格Excel 值获取失败",
    "data": null
}

1，pom导入

    <!-- https://mvnrepository.com/artifact/cn.afterturn/easypoi-annotation -->
    <dependency>
        <groupId>cn.afterturn</groupId>
        <artifactId>easypoi-annotation</artifactId>
        <version>${easypoi.version}</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/cn.afterturn/easypoi-base -->
    <dependency>
        <groupId>cn.afterturn</groupId>
        <artifactId>easypoi-base</artifactId>
        <version>${easypoi.version}</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/cn.afterturn/easypoi-web -->
    <dependency>
        <groupId>cn.afterturn</groupId>
        <artifactId>easypoi-web</artifactId>
        <version>${easypoi.version}</version>
    </dependency>

2,设置导入对象

@Data
public class SuppliesExcelBO implements IExcelModel, IExcelDataModel {

    @NotEmpty(message = "物资名称不能为空")
    @Excel(name = "物资名称", orderNum = "1")
    private String name;
    
    @NotNull(message = "物资类型不能为空")
    @Excel(name = "物资类型", orderNum = "2")
    private Integer typeMax;
    
    @NotEmpty(message = "物资规格不能为空")
    @Excel(name = "物资规格", orderNum = "3")
    private String spec;
    
    @Excel(name = "型号", orderNum = "4")
    private String model;
    
    @Excel(name = "品牌", orderNum = "5")
    private String brand;
    
    @NotNull(message = "参考价格不能为空")
    @Excel(name = "参考价格", orderNum = "6")
    private java.math.BigDecimal price;
    
    @Excel(name = "单位", orderNum = "7")
    private String unit;
    
    @Excel(name = "备注", orderNum = "8")
    private String remark;

    private String errorMsg;

    private Integer rowNum;

    @Override
    public int getRowNum() {
        return rowNum;
    }

    @Override
    public void setRowNum(int rowNum) {
        this.rowNum = rowNum;
    }
}

3,控制器接收请求

    /**
     * 导入物资
     */
    @PostMapping("/import")
    public Result<Integer> importExcel(@RequestParam("file") MultipartFile file) throws Exception {
        //使用EasyPoi获取文件数据，并校验
        ImportParams params = new ImportParams();
        params.setNeedVerfiy(true);
        ExcelImportResult<SuppliesExcelBO> importResult = ExcelImportUtil.importExcelMore(file.getInputStream(), SuppliesExcelBO.class, params);
        //导入校验存在失败则返回失败行
        if(importResult.isVerfiyFail()){
            SuppliesExcelBO a = importResult.getFailList().get(0);
            return ResultUtils.failure(ResultCodeEnum.BAD_REQUEST,"第"+a.getRowNum()+"行，"+a.getErrorMsg());
        }
        return suppliesService.importExcel(importResult.getList());
    }

4,导入对象转换为数据库对象并保存

    public Result importExcel(List<SuppliesExcelBO> suppliesList) {
        List<SuppliesDomain> SuppliesList = new ArrayList<>();
        for(SuppliesExcelBO suppliesExcelBO:suppliesList){
            SuppliesDomain supplies = new SuppliesDomain();
            BeanUtil.copyProperties(suppliesExcelBO, supplies);
            supplies.setStatus(1);
            SuppliesList.add(supplies);
        }
        mapper.insertList(SuppliesList);
        return Result.success();
    }

5,测试导入异常数据

在这里插入图片描述

{
    "success": false,
    "code": "400",
    "msg": "请求参数有误",
    "errorMsg": "第2行，参考价格不能为空, 参考价格Excel 值获取失败",
    "data": null
}
