java实现File文件上传到OSS

以下是Java实现File文件上传到OSS的示例代码：

import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.model.PutObjectRequest;
import com.aliyun.oss.model.PutObjectResult;

import java.io.File;

public class OSSFileUploader {

    // 阿里云 OSS 信息
    private static final String ENDPOINT = "your-endpoint";
    private static final String ACCESS_KEY_ID = "your-access-key-id";
    private static final String ACCESS_KEY_SECRET = "your-access-key-secret";
    private static final String BUCKET_NAME = "your-bucket-name";

    // 上传文件到 OSS
    public static void uploadFile(File file) {
        // 创建 OSS 客户端
        OSS ossClient = new OSSClientBuilder().build(ENDPOINT, ACCESS_KEY_ID, ACCESS_KEY_SECRET);

        // 创建 PutObjectRequest 对象
        PutObjectRequest putObjectRequest = new PutObjectRequest(BUCKET_NAME, file.getName(), file);

        // 上传文件到 OSS
        PutObjectResult putObjectResult = ossClient.putObject(putObjectRequest);

        // 打印上传结果
        System.out.println("File uploaded: " + putObjectResult.getETag());

        // 关闭 OSS 客户端
        ossClient.shutdown();
    }

    public static void main(String[] args) {
        // 上传本地文件
        File file = new File("your-local-file-path");
        uploadFile(file);
    }
}

需要将上述代码中的 `your-endpoint`、`your-access-key-id`、`your-access-key-secret` 和 `your-bucket-name` 替换为自己的阿里云 OSS 相关信息，将 `your-local-file-path` 替换为要上传的本地文件路径。执行 `uploadFile()` 方法即可将本地文件上传到 OSS。
