java 1.8+springboot文件上传+vue3+ts+antdv

1.参考

使用SpringBoot优雅的实现文件上传_51CTO博客_springboot 上传文件

2.postman测试

 报错 ：postman调用时body参数中没有file单词

 Resolved [org.springframework.web.multipart.support.MissingServletRequestPartException: Required request part 'file' is not present]

1）headers设置

 Content-Type    multipart/form-data; boundary=<calculated when request is sent>

2）body

选form-data

key中一定要有file单词，再在旁边文件中选择文件即可

3.报错

Files::getMd5 是Java NIO（New Input/Output）包中Files类的一个静态方法，用于计算文件的MD5哈希值。这个方法在Java 17中引入，因此，要使用这个方法，你需要确保你的Java版本是17或更高。

主要是用a-form包裹了 a upload

 <a-uploadv-model:file-list="fileList"name="文件上传":beforeUpload="beforeUpload"><a-button> 选择文件 </a-button></a-upload> 

 

先定一个formData

用于准备所有信息(包括文件)给axios发送

const formData=new FormData();

FormData应该是一种比较好用的js新格式,参考

                    https://juejin.cn/post/7258171660145803324

获得file

这里的:beforeUpload特别重要，主要是        其获得了上传的file

const beforeUpload=(file)=>{formData.append('file',file)}

formdata.append既可以添加属性给它，也可以添加文件

formstate

  用于收集非附件的其它form字段信息

因为文件上传框是个弹出框，所以用了a-modal

<a-modal>

     <a-form>

          <a-form-item>

            <a-upload>

给a-form绑定了一个属性formstate

<template><div style="margin-left: 16px"><div style="margin-bottom: 16px"><a-button type="primary" :disabled="!hasSelected" :loading="state.loading" @click="start">Reload</a-button><!-- 因为选中的要删除的行的id存在state.selectedRowKeys里面 --><a-button type="primary"  @click="delBook(state.selectedRowKeys)">删除书籍</a-button><a-button type="primary"  @click="addBook">新增书籍</a-button><span style="margin-left: 8px"><template v-if="hasSelected">{{ `Selected ${state.selectedRowKeys.length} items` }}</template></span></div><!--必须指定rowKey，可以是当前data中的一个属性  ，不指定的话就会被全部选中--><a-tablerowKey="id":row-selection="{ selectedRowKeys: state.selectedRowKeys, onChange: onSelectChange }":columns="columns":data-source="data"/></div><!-- 弹出框  a-modal  默认隐藏，是在ContextMenuClick让其显示出来--><a-modalv-model:open="open":title="modalTitle"@ok="handleOk"@cancel="resetForm"okText="确认"cancelText="取消":maskClosable="false":closable="false"><a-formref="formRef":model="formState":rules="rules":label-col="labelCol":wrapper-col="wrapperCol"><a-form-item ref="categoryId" label="分类编号" name="categoryId"><a-inputv-model:value="formState.categoryId"placeholder="分类编号"/></a-form-item><a-form-item ref="name" label="书名" name="name"><a-inputv-model:value="formState.name"placeholder="书名"/></a-form-item><a-form-item ref="author" label="作者" name="author"><a-inputv-model:value="formState.author"placeholder="作者"/></a-form-item><a-form-item ref="description" label="简介" name="description"><a-inputv-model:value="formState.description"placeholder="简介"/></a-form-item><a-form-item name="fileList" label="上传文件"><!-- <a-uploadv-model:file-list="fileList"name="文件上传"action="":customRequest="upDown":beforeUpload="beforeUpload"@remove="removeFile"accept=".xlsx,.xls"> --><a-uploadv-model:file-list="fileList"name="文件上传":beforeUpload="beforeUpload"><a-button> 选择文件 </a-button></a-upload> </a-form-item></a-form></a-modal></template><script lang="ts" setup>import { message, Modal, Upload} from 'ant-design-vue';

发给axios

由a-modal上的handleOk来触发调用后端

  <a-modalv-model:open="open":title="modalTitle"@ok="handleOk"@cancel="resetForm"okText="确认"cancelText="取消":maskClosable="false":closable="false">

 AddGoodsAPI(formData)
