antdesignvue + AWS-S3实现Minio大文件分片上传

FinelyYang2024-11-05 11:31

一、后端：

1.引入pom

java 复制代码 
        <dependency>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-java-sdk-s3</artifactId>
            <version>1.12.263</version>
        </dependency>

2.配置application.yml

java 复制代码 
jeecg:
  minio:
    minioUrl: http://localhost:9000
    minioName: minioadmin
    minioPass: Aa123456@admin
    bucketName: exam-bucket

3.aws配置

java 复制代码 
package com.ynfy.config;

import com.amazonaws.ClientConfiguration;
import com.amazonaws.Protocol;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.client.builder.AwsClientBuilder;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class AmazonS3Config {

    @Value(value = "${jeecg.minio.minioUrl}")
    private String minioUrl;

    @Value(value = "${jeecg.minio.minioName}")
    private String minioName;

    @Value(value = "${jeecg.minio.minioPass}")
    private String minioPass;

    @Bean(name = "amazonS3Client")
    public AmazonS3 amazonS3Client() {
        //设置连接时的参数
        ClientConfiguration config = new ClientConfiguration();
        //设置连接方式为HTTP，可选参数为HTTP和HTTPS
        config.setProtocol(Protocol.HTTP);
        //设置网络访问超时时间
        config.setConnectionTimeout(5000);
        config.setUseExpectContinue(true);
        AWSCredentials credentials = new BasicAWSCredentials(minioName, minioPass);
        //设置Endpoint
        AwsClientBuilder.EndpointConfiguration endPoint = new AwsClientBuilder.EndpointConfiguration(minioUrl, Regions.US_EAST_1.name());
        AmazonS3 amazonS3 = AmazonS3ClientBuilder.standard()
                .withClientConfiguration(config)
                .withCredentials(new AWSStaticCredentialsProvider(credentials))
                .withEndpointConfiguration(endPoint)
                .withPathStyleAccessEnabled(true).build();
        return amazonS3;
    }

}

4.新建数据库表aws_s3_upload

用于记录上传的文件信息：md5值，对象key等信息。

5.接口IAwsS3UploadService：

java 复制代码 
package com.ynfy.buss.awss3upload.service;

import com.baomidou.mybatisplus.extension.service.IService;
import com.ynfy.buss.awss3upload.entity.AwsS3Upload;
import com.ynfy.buss.awss3upload.entity.TaskParam;
import com.ynfy.buss.awss3upload.entity.dto.TaskInfoDTO;

import java.util.Map;

/**
 * @Description: AWS.S3 大文件分片上传
 * @Author: jeecg-boot
 * @Date: 2024-10-31
 * @Version: V1.0
 */
public interface IAwsS3UploadService extends IService<AwsS3Upload> {

    /**
     * 根据md5标识获取分片上传任务
     *
     * @param identifier
     * @return
     */
    AwsS3Upload getByIdentifier(String identifier);

    /**
     * 初始化一个任务
     */
    TaskInfoDTO initTask(TaskParam param);

    /**
     * 获取上传进度
     *
     * @param identifier
     * @return
     */
    TaskInfoDTO getTaskInfo(String identifier);


    /**
     * 生成预签名上传url
     *
     * @param bucket    桶名
     * @param objectKey 对象的key
     * @param params    额外的参数
     * @return
     */
    String genPreSignUploadUrl(String bucket, String objectKey, Map<String, String> params);

    /**
     * 合并分片
     *
     * @param identifier
     */
    void merge(String identifier);
}

6.接口实现类AwsS3UploadServiceImpl：

java 复制代码 
package com.ynfy.buss.awss3upload.service.impl;

import cn.hutool.core.date.DateUtil;
import cn.hutool.core.util.StrUtil;
import com.amazonaws.HttpMethod;
import com.amazonaws.services.s3.AmazonS3;

import com.ynfy.buss.awss3upload.entity.AwsS3Upload;
import com.ynfy.buss.awss3upload.entity.TaskParam;
import com.ynfy.buss.awss3upload.entity.dto.TaskInfoDTO;
import com.ynfy.buss.awss3upload.entity.dto.TaskRecordDTO;
import com.ynfy.buss.awss3upload.mapper.AwsS3UploadMapper;
import com.ynfy.buss.awss3upload.service.IAwsS3UploadService;
import org.jeecg.common.exception.JeecgBootException;

import java.util.Objects;
import java.util.stream.Collectors;

7.接口controller类AwsS3UploadController：

java 复制代码 
package com.ynfy.buss.awss3upload.controller;

import com.ynfy.buss.awss3upload.entity.AwsS3Upload;

     *
     * @param identifier 文件md5
     * @return
     */
    @GetMapping("/task/{identifier}")
    public Result<TaskInfoDTO> taskInfo(@PathVariable("identifier") String identifier) {

        awsS3UploadService.merge(identifier);
        return Result.OK();
    }

}

入参类TaskParam：

java 复制代码 
package com.ynfy.buss.awss3upload.entity;

import lombok.Data;
import lombok.ToString;
import lombok.experimental.Accessors;

import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotNull;

@Data
@ToString
@Accessors(chain = true)
public class TaskParam {

    /**
     * 文件唯一标识(MD5)
     */
    @NotBlank(message = "文件标识不能为空")
    private String identifier;

    /**
     * 文件大小（byte）
     */
    @NotNull(message = "文件大小不能为空")
    private Long totalSize;

    /**
     * 分片大小（byte）
     */
    @NotNull(message = "分片大小不能为空")
    private Long chunkSize;

    /**
     * 文件名称
     */
    @NotBlank(message = "文件名称不能为空")
    private String fileName;
}

dto

java 复制代码 
package com.ynfy.buss.awss3upload.entity.dto;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
import lombok.experimental.Accessors;

@AllArgsConstructor
@Accessors(chain = true)
public class TaskInfoDTO {

    /**
     * 是否完成上传（是否已经合并分片）
     */
    private boolean finished;

    /**
     * 文件地址
     */
    private String path;

    /**
     * 上传记录
     */
    private TaskRecordDTO taskRecord;

}
java 复制代码 
package com.ynfy.buss.awss3upload.entity.dto;

        TaskRecordDTO dto = new TaskRecordDTO();
        BeanUtil.copyProperties(task, dto);
        return dto;
    }
}

常量：

java 复制代码 
package com.ynfy.buss.awss3upload.constant;


public interface MinioConstant {

    // 分块大小
    int DEFAULT_CHUNK_SIZE = 10 * 1024 * 1024;

    // 预签名url过期时间(ms)
    Long PRE_SIGN_URL_EXPIRE = 60 * 10 * 1000L;
}

      } else {
        queue.push(() => uploadNext(partNumber).then(res => {
          // 单片文件上传完成再更新上传进度
          updateProcess(res.uploadedSize);
        }));
      }
    }
    if (queue.getLength() == 0) {

/**
 * el-upload 自定义上传方法入口
 */
const handleHttpRequest = async (options) => {

  const file = options.file;
  const task = await getTaskInfo(file);
  if (task) {
    const { finished, taskRecord } = task;
    const { fileIdentifier: identifier } = taskRecord;
    if (finished) {
      emit("update:modelValue", taskRecord.objectKey);
      onSuccess(null, file);
    } else {
      const errorList: any = await handleUpload(file, taskRecord, options);
      if (errorList.length > 0) {
        createMessage.error("部分分片上次失败，请尝试重新上传文件");
        return;
      }

/**

 * 如果文件存在上传队列任务对象，则停止该队列的任务
 */
const handleRemoveFile = (uploadFile, uploadFiles) => {
  fileList.value = fileList.value.filter(item => item.uid != uploadFile.uid);
  const queueObject = fileUploadChunkQueue[uploadFile.uid];
  if (queueObject) {
    queueObject.stop();
    fileUploadChunkQueue[uploadFile.uid] = undefined;
  }
  emit("update:modelValue", "");
};

const handleChange = (info) => {
  fileList.value = info.fileList;
};
</script>

<style scoped>

</style>

2.接口 awss3.ts

javascript 复制代码 
import { defHttp } from "/@/utils/http/axios";

/**
 * 根据文件的md5获取未上传完的任务
 * @param identifier 文件md5
 */
export const taskInfo = (identifier) => {
  return defHttp.get({ url: `/awsS3Upload/task/${identifier}` });
};

/**
 * 初始化一个分片上传任务
 * @param identifier 文件md5
 * @param fileName 文件名称
 * @param totalSize 文件大小
 * @param chunkSize 分块大小
 */
export const initTask = (params) => {
  return defHttp.post({ url: "/awsS3Upload/task/init", params });
};

/**
 * 获取预签名分片上传地址
 * @param identifier 文件md5
 * @param partNumber 分片编号
 */
export const preSignUrl = ({ identifier, partNumber }) => {
  return defHttp.get({ url: `/awsS3Upload/task/${identifier}/${partNumber}` });
};

/**
 * 合并分片
 * @param identifier
 */
export const merge = (identifier) => {
  return defHttp.post({ url: `/awsS3Upload/task/merge/${identifier}` });
};

3.使用

javascript 复制代码 
<AwsS3Upload v-model:modelValue="form.videoId"
                     @update:modelValue="(value)=>{ form.videoId = value }"  />
