Java根据模板实现excel导出标准化

const exportXls = async () => {
    var now = moment(new Date()).format('YYYYMMDDHHMMSS')
    let name = '商品收发明细表.xls'
    const res = await proxy.$api.invOrder.goodsRdDetail.export({...condForm.value})
    let data = res.data;
    let url = window.URL.createObjectURL(new Blob([data], ))
    let link = document.createElement('a')
    link.style.display = 'none'
    link.href = url;
    console.log(link);
    link.setAttribute('download', now + name)
    document.body.appendChild(link)
    link.click()
    document.body.removeChild(link)
}
