Java大文件上传、分片上传、多文件上传、断点续传、上传文件minio、分片上传minio等解决方案

以下是一个使用Java进行大文件上传、分片上传、多文件上传以及断点续传的简化示例，同时包括了如何使用MinIO进行文件上传的代码实现。

import io.minio.MinioClient;
import io.minio.UploadObjectArgs;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;
 
public class FileUploader {
 
    private MinioClient minioClient;
    private String bucketName;
 
    public FileUploader(MinioClient minioClient, String bucketName) {
        this.minioClient = minioClient;
        this.bucketName = bucketName;
    }
 
    public void uploadFile(String objectName, InputStream data) throws Exception {
        UploadObjectArgs args = UploadObjectArgs.builder()
                .bucket(bucketName)
                .object(objectName)
                .contentType("application/octet-stream")
                .stream(data, data.available(), -1)
                .build();
        minioClient.uploadObject(args);
    }
 
    public void uploadFileWithMetadata(String objectName, InputStream data, Map<String, String> metadata) throws Exception {
        UploadObjectArgs args = UploadObjectArgs.builder()
                .bucket(bucketName)
                .object(objectName)
                .contentType("application/octet-stream")
                .stream(data, data.available(), -1)
                .metadata(metadata)
                .build();
        minioClient.uploadObject(args);
    }
 
    // 分片上传逻辑
    public void uploadFileInChunks(String objectName, InputStream data, int chunkSize) throws Exception {
        // 分片逻辑实现
    }
 
    // 断点续传逻辑
    public void uploadFileResume(String objectName, InputStream data, long offset) throws Exception {
        // 断点续传逻辑实现
    }
 
    // 多文件上传逻辑
    public void uploadMultipleFiles(Map<String, InputStream> files) throws Exception {
        for (Map.Entry<String, InputStream> entry : files.entrySet()) {
            uploadFile(entry.getKey(), entry.getValue());
            entry.getValue().close(); // 上传后关闭流
        }
    }
 
    public static void main(String[] args) {
        // MinIO客户端初始化
        MinioClient minioClient = new MinioClient.Builder()
                .endpoint("http://127.0.0.1:9000")
                .credentials("minioadmin", "minioadmin")
                .build();
 
        FileUploader fileUploader = new FileUploader(minioClient, "my-bucket");
 
        try {
            // 上传单个文件
