定义Vo实体类

@Data
@EqualsAndHashCode(callSuper = false)
public class ProductExportVo implements Serializable {
    private static final long serialVersionUID = 1L;
    /**
     * 商品编号
     */
    @Excel(name = "商品编号", orderNum = "0", width = 15)
    private String productNo;

    /**
     * 商品名称
     */
    @Excel(name = "商品名称", orderNum = "1", width = 25)
    private String productName;


    /**
     * 商品类型 
     */
    @Excel(name = "商品类型", orderNum = "2", width = 15)
    private String productType;

    /**
     * 面值
     */
    @Excel(name = "面值", orderNum = "3", width = 15)
    private Integer productDeno;

    /**
     * 销售区域 0 省域 1 市域 2 全国
     */
    @Excel(name = "销售区域", orderNum = "4", width = 15)
    private String productSalesArea;

    /**
     * 销售价
     */
    @Excel(name = "销售价", orderNum = "5", width = 15)
    private BigDecimal productPrice;

    /**
     * 状态 0 下架 1 上架
     */
    @Excel(name = "状态", orderNum = "6", width = 15)
    private String productStatus;

    /**
     * 创建时间
     */
    @Excel(name = "创建时间", orderNum = "7", width = 25, exportFormat = "yyyy-MM-dd HH:mm:ss")
    private String productCreateTime;

    /**
     * 修改时间
     */
    @Excel(name = "修改时间", orderNum = "8", width = 25, exportFormat = "yyyy-MM-dd HH:mm:ss")
    private String productModifyTime;
}

　　

控制层

@PostMapping("products/exportAsExcel")
public void exportAsExcel(HttpServletResponse response,ProductSearchDto productSearchDto) {
    final String name = SecurityContextHolder.getContext().getAuthentication().getName();
    log.info("用户[{}, {}]查导出商品表", name, request.getRemoteAddr());
    if (productSearchDto.getProductDenoRange() != null && productSearchDto.getProductDenoRange().length < 2) {
        productSearchDto.setProductDenoRange(null);
    }
    if (productSearchDto.getProductPriceRange() != null && productSearchDto.getProductPriceRange().length < 2) {
        productSearchDto.setProductPriceRange(null);
    }
     List<ProductExportVo> productList = productService.queryProduct(productSearchDto);
    try {
        ExcelUtils.exportExcel(productList,"商品信息表","商品信息",ProductExportVo.class,"商品信息",response);
    } catch (IOException e) {
        e.printStackTrace();
    }

}

　　

前端Vue

downLoad(parmas) {
      var temp = document.createElement("form");
      temp.action = `/api/products/exportAsExcel?${qs.stringify(parmas)}`;
      temp.method = "post";
      temp.style.display = "none";
      document.body.appendChild(temp);
      temp.submit();
    },
