Java大文件分片上传超详细教程(minio版)
更新时间：2024年08月02日 09:41:28 作者：儿时可乖了
Minio是一个开源的分布式对象存储系统,它允许用户在存储服务上存储和检索数据,下面这篇文章主要给大家介绍了关于Java大文件分片上传(minio版)的相关资料,文中通过代码介绍的非常详细,需要的朋友可以参考下
第一步：pom引入minio
<!--minio大文件上传-->
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.0.3</version>
</dependency>
第二步：配置minio
# minio 配置（大文件分片上传使用）
minio:
endpoint: ${MINIO_ENDPOINT:http://minio服务IP:端口号}
accesskey: ${MINIO_ASSESSKEY:密钥}
secretkey: ${MINIO_SECRETKEY:密匙}
bucket: ${MINIO_BUCKET:桶名称}
第三步：自定义minio客户端与工具类
1. 自定义客户端
package com.gcddd.visual.uav.largeFileUpload.util;
import com.google.common.collect.Multimap;
import io.minio.CreateMultipartUploadResponse;
import io.minio.ListPartsResponse;
import io.minio.MinioClient;
import io.minio.ObjectWriteResponse;
import io.minio.errors.*;
import io.minio.messages.Part;
import java.io.IOException;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
/**
* 自定义minio
* @date 2023-09-15
*/
public class CustomMinioClient extends MinioClient {
public CustomMinioClient(MinioClient client) {
super(client);
}
public String initMultiPartUpload(String bucket, String region, String object, Multimap<String, String> headers, Multimap<String, String> extraQueryParams) throws IOException, InvalidKeyException, NoSuchAlgorithmException, InsufficientDataException, ServerException, InternalException, XmlParserException, InvalidResponseException, ErrorResponseException {
CreateMultipartUploadResponse response = this.createMultipartUpload(bucket, region, object, headers, extraQueryParams);
return response.result().uploadId();
}
public ObjectWriteResponse mergeMultipartUpload(String bucketName, String region, String objectName, String uploadId, Part[] parts, Multimap<String, String> extraHeaders, Multimap<String, String> extraQueryParams) throws IOException, InvalidKeyException, NoSuchAlgorithmException, InsufficientDataException, ServerException, InternalException, XmlParserException, InvalidResponseException, ErrorResponseException {
return this.completeMultipartUpload(bucketName, region, objectName, uploadId, parts, extraHeaders, extraQueryParams);
}
public ListPartsResponse listMultipart(String bucketName, String region, String objectName, Integer maxParts, Integer partNumberMarker, String uploadId, Multimap<String, String> extraHeaders, Multimap<String, String> extraQueryParams) throws NoSuchAlgorithmException, InsufficientDataException, IOException, InvalidKeyException, ServerException, XmlParserException, ErrorResponseException, InternalException, InvalidResponseException {
return this.listParts(bucketName, region, objectName, maxParts, partNumberMarker, uploadId, extraHeaders, extraQueryParams);
}
}
2.封装minio配置
package com.gcddd.visual.uav.largeFileUpload.configurer;
import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
/**
* @Description: MinioProperties
* minio配置类
*/
@ConfigurationProperties(prefix = "minio")
@Getter
@Setter
public class MinioProperties {
private String endpoint;
private String accesskey;
private String secretkey;
private String bucket;
}
3.上传工具类
package com.gcddd.visual.uav.largeFileUpload.configurer;
import cn.hutool.core.util.StrUtil;
import com.gcddd.visual.uav.largeFileUpload.util.CustomMinioClient;
import com.google.common.collect.HashMultimap;
import io.minio.*;
import io.minio.http.Method;
import io.minio.messages.Part;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.concurrent.TimeUnit;
/**
* @Description: MinIoUtils
* 工具类
*/
@Component
@Configuration
@EnableConfigurationProperties({MinioProperties.class})
public class MinIoUtils {
private final MinioProperties minioProperties;
private CustomMinioClient customMinioClient;
public MinIoUtils(MinioProperties minioProperties) {
this.minioProperties = minioProperties;
}
@PostConstruct
public void init() {
MinioClient minioClient = MinioClient.builder()
.endpoint(minioProperties.getEndpoint())
.credentials(minioProperties.getAccesskey(), minioProperties.getSecretkey())
.build();
customMinioClient = new CustomMinioClient(minioClient);
}
/**
* 单文件签名上传
*
* @param objectName 文件全路径名称
* @return /
*/
public String getUploadObjectUrl(String objectName) {
try {
return customMinioClient.getPresignedObjectUrl(
GetPresignedObjectUrlArgs.builder()
.method(Method.PUT)
.bucket(minioProperties.getBucket())
.object(objectName)
.expiry(1, TimeUnit.DAYS)
//.extraHeaders(headers)
.build()
);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
/**
* 初始化分片上传
*
* @param objectName 文件全路径名称
* @param partCount 分片数量
* @param contentType 类型，如果类型使用默认流会导致无法预览
* @return /
*/
public Map<String, Object> initMultiPartUpload(String objectName, int partCount, String contentType) {
Map<String, Object> result = new HashMap<>();
try {
if (StrUtil.isBlank(contentType)) {
contentType = "application/octet-stream";
}
HashMultimap<String, String> headers = HashMultimap.create();
headers.put("Content-Type", contentType);
String uploadId = customMinioClient.initMultiPartUpload(minioProperties.getBucket(), null, objectName, headers, null);
result.put("uploadId", uploadId);
List<String> partList = new ArrayList<>();
Map<String, String> reqParams = new HashMap<>();
//reqParams.put("response-content-type", "application/json");
reqParams.put("uploadId", uploadId);
for (int i = 1; i <= partCount; i++) {
reqParams.put("partNumber", String.valueOf(i));
String uploadUrl = customMinioClient.getPresignedObjectUrl(
GetPresignedObjectUrlArgs.builder()
.method(Method.PUT)
.bucket(minioProperties.getBucket())
.object(objectName)
.expiry(1, TimeUnit.DAYS)
.extraQueryParams(reqParams)
.build());
partList.add(uploadUrl);
}
result.put("uploadUrls", partList);
} catch (Exception e) {
e.printStackTrace();
return null;
}
return result;
}
/**
* 分片上传完后合并
*
* @param objectName 文件全路径名称
* @param uploadId 返回的uploadId
* @return /
*/
public boolean mergeMultipartUpload(String objectName, String uploadId) {
try {
//TODO::目前仅做了最大1000分片
Part[] parts = new Part[1000];
ListPartsResponse partResult = customMinioClient.listMultipart(minioProperties.getBucket(), null, objectName, 1000, 0, uploadId, null, null);
int partNumber = 1;
for (Part part : partResult.result().partList()) {
parts[partNumber - 1] = new Part(partNumber, part.etag());
partNumber++;
}
customMinioClient.mergeMultipartUpload(minioProperties.getBucket(), null, objectName, uploadId, parts, null, null);
} catch (Exception e) {
e.printStackTrace();
return false;
}
return true;
}
}
4.service
package com.gcddd.visual.uav.largeFileUpload.service;
import java.util.Map;
/**
* @date 2023-09-13
*/
public interface UploadService {
/**
* 分片上传初始化
*
* @param path 路径
* @param filename 文件名
* @param partCount 分片数量
* @param contentType /
* @return /
*/
Map<String, Object> initMultiPartUpload(String path, String filename, Integer partCount, String contentType);
/**
* 完成分片上传
*
* @param objectName 文件名
* @param uploadId 标识
* @return /
*/
boolean mergeMultipartUpload(String objectName, String uploadId);
}
5.service实现
package com.gcddd.visual.uav.largeFileUpload.service.impl;
import com.gcddd.visual.uav.largeFileUpload.configurer.MinIoUtils;
import com.gcddd.visual.uav.largeFileUpload.service.UploadService;
import com.google.common.collect.ImmutableList;
import com.google.common.collect.ImmutableMap;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Service;
import java.util.Map;
/**
* @date 2023-09-13
*/
@Service
@RequiredArgsConstructor
public class UploadServiceImpl implements UploadService {
private final MinIoUtils minIoUtils;
@Override
public Map<String, Object> initMultiPartUpload(String path, String filename, Integer partCount, String contentType) {
path = path.replaceAll("/+", "/");
if (path.indexOf("/") == 0) {
path = path.substring(1);
}
String filePath = path + "/" + filename;
Map<String, Object> result;
// 单文件，直接上传
if (partCount == 1) {
String uploadObjectUrl = minIoUtils.getUploadObjectUrl(filePath);
result = ImmutableMap.of("uploadUrls", ImmutableList.of(uploadObjectUrl));
} else {//多文件，分片上传
result = minIoUtils.initMultiPartUpload(filePath, partCount, contentType);
}
return result;
}
@Override
public boolean mergeMultipartUpload(String objectName, String uploadId) {
return minIoUtils.mergeMultipartUpload(objectName, uploadId);
}
}
6.接口控制器
import cn.hutool.core.lang.Assert;
import cn.hutool.json.JSONObject;
import com.gcddd.visual.uav.largeFileUpload.service.UploadService;
import com.gcddd.visual.uav.util.DateUtils;
import com.google.common.collect.ImmutableMap;
import io.swagger.v3.oas.annotations.security.SecurityRequirement;
import io.swagger.v3.oas.annotations.tags.Tag;
import lombok.RequiredArgsConstructor;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;
import java.util.Map;
/**
* 大文件上传控制器
*/
@RestController
@RequiredArgsConstructor
@RequestMapping("/largeFileUpload" )
@Tag(description = "largeFileUpload" , name = "大文件分片上传" )
@SecurityRequirement(name = HttpHeaders.AUTHORIZATION)
public class uploadController {
private final UploadService uploadService;
// 1.用户调用初始化接口，后端调用minio初始化，得到uploadId，生成每个分片的minio上传url
//初始化 示例： $ curl --location --request POST 'http://127.0.0.1:9998/admin/largeFileUpload/multipart/init' \
// --header 'Content-Type: application/json' \
// --data-raw '{
// "filename": "result.png",
// "partCount": 2
// }'
// 返回示例：
//{
// "uploadId": "eb163e3d-bbf5-48ae-aa56-85cf2a3c0fa3",
// "uploadUrls": [
// "http://ip:端口号/uav/20230913/result.png?uploadId=eb163e3d-bbf5-48ae-aa56-85cf2a3c0fa3&partNumber=1&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=lengleng%2F20230913%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20230913T031427Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&X-Amz-Signature=9e7bd28d6f4d42d0ed447750cadcd8782ccc2648a66ecb25a1e7639593ad7dd6",
// "http://ip:端口号/uav/20230913/result.png?uploadId=eb163e3d-bbf5-48ae-aa56-85cf2a3c0fa3&partNumber=2&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=lengleng%2F20230913%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20230913T031427Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&X-Amz-Signature=60d31989b9dc3bdacf6bbc9c13cb5c982f79b1e3a0bbcb948e0ec90fede2f9f3"
// ]
//}
// 2.用户调用对应分片的上传地址，多次上传会覆盖
// 示例：
// curl --location --request PUT 'http://ip:端口号/uav/20230913/result.png?uploadId=eb163e3d-bbf5-48ae-aa56-85cf2a3c0fa3&partNumber=1&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=lengleng%2F20230913%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20230913T031427Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&X-Amz-Signature=9e7bd28d6f4d42d0ed447750cadcd8782ccc2648a66ecb25a1e7639593ad7dd6' \
// --header 'Content-Type: application/octet-stream' \
// --data-binary '@/D:/jpgone'
// curl --location --request PUT 'http://ip:端口号/uav/20230913/result.png?uploadId=eb163e3d-bbf5-48ae-aa56-85cf2a3c0fa3&partNumber=2&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=lengleng%2F20230913%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20230913T031427Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&X-Amz-Signature=60d31989b9dc3bdacf6bbc9c13cb5c982f79b1e3a0bbcb948e0ec90fede2f9f3' \
// --header 'Content-Type: application/octet-stream' \
// --data-binary '@/D:/jpgtwo'
// 3.调用完成接口，后端查询所有上传的分片并合并，uploadId为第一步返回的uploadId
// 示例：
// curl --location --request PUT '127.0.0.1:8006/multipart/complete' \
// --header 'Content-Type: application/json' \
// --data-raw '{
// "objectName":"20230913/result.png",
// "uploadId":"eb163e3d-bbf5-48ae-aa56-85cf2a3c0fa3"
// }'
/**
* 分片初始化
*
* @param requestParam 请求参数
* @return /
*/
@PostMapping("/multipart/init")
public ResponseEntity<Object> initMultiPartUpload(@RequestBody JSONObject requestParam) {
// 路径（存入minio的路径）
String pathText = DateUtils.getTodays("yyyyMMdd");//当前日期
String path = requestParam.getStr("path", pathText);
// 文件名
String filename = requestParam.getStr("filename", "test.obj");
// content-type
String contentType = requestParam.getStr("contentType", "application/octet-stream");
// md5-可进行秒传判断
String md5 = requestParam.getStr("md5", "");
// 分片数量
Integer partCount = requestParam.getInt("partCount", 100);
//TODO::业务判断+秒传判断
Map<String, Object> result = uploadService.initMultiPartUpload(path, filename, partCount, contentType);
return new ResponseEntity<>(result, HttpStatus.OK);
}
/**
* 合并分片文件，完成上传
*
* @param requestParam 用户参数
* @return /
*/
@PutMapping("/multipart/complete")
public ResponseEntity<Object> completeMultiPartUpload(
@RequestBody JSONObject requestParam
) {
// 文件名完整路径
String objectName = requestParam.getStr("objectName");
//初始化返回的uploadId
String uploadId = requestParam.getStr("uploadId");
Assert.notNull(objectName, "objectName must not be null");
Assert.notNull(uploadId, "uploadId must not be null");
boolean result = uploadService.mergeMultipartUpload(objectName, uploadId);
return new ResponseEntity<>(ImmutableMap.of("success", result), HttpStatus.OK);
}
}
第四步：文件切片
把result.png图片以500M大小切片，重命名为result.png.后缀
split -b 500m result.png result.png.
第五步：示例截图
这里测试为把result.png切为2片，返回了uploadId 和两个minio文件上传地址
分片上传的地址上传文件，请求方式为put
合并文件，完成上传
检查minio是否成功
