Java 文件上传云存储

基于springboot+vue

前端vue：

<!--  按钮：点击跳出弹框  -->
<div>
  <el-button type="primary" size="mini" @click="upload.open = true">
    系统自动生成简历
  </el-button>
</div>

<!-- 弹框 -->
<el-dialog :title="upload.title" :visible.sync="upload.open" width="400px" append-to-body>
  <el-upload ref="upload" :limit="1" a***ept=".docx" :headers="upload.headers"
             :action="upload.url" :disabled="upload.isUploading"
             :on-progress="handleFileUploadProgress" :on-su***ess="handleFileSu***ess" :auto-upload="false" drag>
    <i class="el-icon-upload"></i>
    <div class="el-upload__text">将文件拖到此处，或<em>点击上传</em></div>
    <div class="el-upload__tip text-center" slot="tip">

      <span>仅允许导入docx格式文件。</span>
      <el-link type="primary" :underline="false" style="font-size:12px;vertical-align: baseline;"
               @click="importTemplate">下载模板
      </el-link>
    </div>
  </el-upload>
  <div slot="footer" class="dialog-footer">
    <el-button @click="upload.open = false">取 消</el-button>
    <el-button type="primary" @click="submitFileForm">确 定</el-button>
  </div>
</el-dialog>

<!-- 用户导入参数 -->
upload: {
  // 是否显示弹出层（用户导入）
  open: false,
  // 弹出层标题（用户导入）
  title: "",
  // 是否禁用上传
  isUploading: false,
  // 是否更新已经存在的用户数据
  updateSupport: '',
  // 设置上传的请求头部
  headers: {Authorization: "Bearer " + getToken()},
  // 上传的地址
  url: process.env.VUE_APP_BASE_API + "/upload"  //调用后端的接口
},

<!-- methods的方法-->
handleFileUploadProgress(event, file, fileList) {
  this.upload.isUploading = true;
},
// 文件上传成功处理
handleFileSu***ess(response, file, fileList) {
  if (response.code === 200){
      this.form.fileNoteUrl = response.fileName
  }
  console.log(this.form.fileNoteUrl)
  this.upload.open = false;
  this.upload.isUploading = false;
  this.$refs.upload.clearFiles();
  this.$alert("<div style='overflow: auto;overflow-x: hidden;max-height: 70vh;padding: 10px 20px 0;'>" + response.msg + "</div>", "导入结果", {dangerouslyUseHTMLString: true});
},
importTemplate() {
  let fileName = '系统生成简历模板.docx';
  //下载模板的地址
  let url = "http://2024/12/11/716021d5-3132-4084-8ed2-0858d5cd505f.docx";
  downloadFile(url, fileName);
},
// 提交上传文件
submitFileForm() {
  this.$refs.upload.submit();
},

后端Java：

//通用上传请求（单个）
public AjaxResult uploadFileForOss(HttpServletRequest request, MultipartFile file) {
    String url = null;
    try {
        MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
        // 单个文件
        MultipartFile myfile = multipartRequest.getFile("file");
        log.info("上传文件：" + myfile != null ? myfile.getOriginalFilename() : null);
        log.info("文件大小："+myfile.getSize());
        log.info("文件位置："+myfile.getInputStream());
        url = ossService.uploadFile(myfile);          //上传文件至云存储

        AjaxResult ajax = AjaxResult.su***ess();
        ajax.put("url", url);
        ajax.put("fileName", url);
        ajax.put("newFileName", FileUtils.getName(url));
        ajax.put("originalFilename", file.getOriginalFilename());
        return ajax;
    } catch (Exception e) {
        e.printStackTrace();
        return AjaxResult.error(e.getMessage());
    }
}

// 上传文件至云存储
public String uploadFile(MultipartFile file) throws Exception {
    // 填写存储桶（Bucket）所在地域对应的 endpoint 和 Region。
    // 以华东 - 苏州为例，endpoint 填写 https://。。。。，Region 填写 w1。
    String objectName = DateUtils.dateTimeNow("yyyy/MM/dd/") + file.getOriginalFilename();
    // 创建 AmazonS3 实例。
    // 创建 AmazonS3 实例。
    AwsClientBuilder.EndpointConfiguration endpointConfiguration = new AwsClientBuilder.EndpointConfiguration(this.endpointEOS, this.regionEOS);
    BasicAWSCredentials credentials = new BasicAWSCredentials(this.a***essKeyIdEOS, this.secretA***essKeyEOS);
    AWSCredentialsProvider credentialsProvider = new AWSStati***redentialsProvider(credentials);
    AmazonS3 client = AmazonS3ClientBuilder.standard()
            .withEndpointConfiguration(endpointConfiguration)
            .withPathStyleA***essEnabled(true)
            .withCredentials(credentialsProvider).build();
    // 上传 byte 数组。
    byte[] data = file.getBytes();
    client.putObject(this.bucketNameEOS, objectName, new ByteArrayInputStream(data), null);
    //文件上传成功后设置文件的访问权限为公开读
    client.setObjectAcl(this.bucketNameEOS, objectName, CannedA***essControlList.PublicRead);

    return this.generateFullUrl(objectName);
}

/**
 * 生成完整的文件地址
 *
 * @param objectName
 * @return
 */
private String generateFullUrl(String objectName) {
    String sb = a***essUrlEOS +
            "/" +
            objectName;
    return sb;
}
