java实现阿里云文件存储OSS

**Java 实现阿里云文件存储 OSS**

阿里云文件存储（OSS）是一种高可用的、分布式的对象存储服务，支持多种协议和接口。通过 Java SDK，可以轻松地与 OSS 进行交互，实现文件上传、下载、删除等操作。

**依赖和配置**

首先，我们需要在项目中添加阿里云 OSS 的依赖：

xml<dependency>
 <groupId>com.aliyun.oss</groupId>
 <artifactId>aliyun-sdk-oss</artifactId>
 <version>1.10.0</version>
</dependency>

public class OssClientExample {
 public static void main(String[] args) {
 // 初始化 OSS 客户端 String accessKeyId = "您的AccessKeyId";
 String accessKeySecret = "您的AccessKeySecret";
 String endpoint = "您的OSS域名";

 OSS oss = new OSSClient(endpoint, accessKeyId, accessKeySecret);
 }
}

 //上传文件 String bucketName = "您的Bucket名称";
 String objectKey = "您的ObjectKey";
 String filePath = "/path/to/your/file.txt";

 try {
 oss.putObject(bucketName, objectKey, new File(filePath));
 System.out.println("Upload file success!");
 } catch (Exception e) {
 System.err.println("Upload file failed: " + e.getMessage());
 }
 }
}

 System.out.println("Download file success!");
 } catch (Exception e) {

 try {

 System.out.println("Delete file success!");
 } catch (Exception e) {
 System.err.println("Delete file failed: " + e.getMessage());
 }
 }
