2.代码

ImportExcel.java：

public static List<GoodsHasImgModel> analysisExcelFileEasyPoi(MultipartFile file) throws Exception {
    ImportParams params = new ImportParams();
    params.setNeedSave(false);
　　 //解析后的图片字段存放的是图片的地址，需要在GoodsModel中配置图片存放路径
    List<GoodsModel> result = ExcelImportUtil.importExcel(file.getInputStream(), GoodsModel.class, params);
    for (GoodsModel goodsModel : result) {
        if (StringUtils.isNotEmpty(goodsModel.getGoodsPic())) {
　　　　　　　　//将图片文件转为base64图片
            File file1 = new File(goodsModel.getGoodsPic());
            FileInputStream inputStream = new FileInputStream(file1);
            byte[] buffer = new byte[inputStream.available()];
            if (inputStream.read(buffer) == -1) {
                inputStream.close();
            }
            StringBuilder imageBase64 = new StringBuilder(Base64.getEncoder().encodeToString(buffer));
            goodsHasImgModel.setGoodsPic(new String(imageBase64));
        }
    }
    return result;
}

@ExcelTarget("goodsEntity")
@Data
@Component
public class GoodsHasImgModel {

    @Excel(name = "商品名称")
    private String goodsName;
　　
　　 //savePath配置的是解析excel后存放图片的路径
    @Excel(name = "商品照片", type = 2, width = 20, height = 10, imageType = 1, savePath = "/home/file/img")
    private String goodsPic;

　　 ...
}

删除临时图片

String[] fileList = new File(savePath).list();
for (String str : fileList) {
    File file1 = new File(savePath + "/" + str);
    if (file1.isFile()) {
        logger.info("清理图片缓存：" + str + (file1.delete() ? "成功" : "失败"));
    }
}
