1.1 创建阿里OSS bucket
OSS Java SDK 兼容性和示例代码_对象存储(OSS)-阿里云帮助中心 (aliyun.com)
1.2 编写工具类
package com.geji.utils;
import com.aliyun.oss.ClientException;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.OSSException;
import com.aliyun.oss.model.PutObjectRequest;
import com.aliyun.oss.model.PutObjectResult;
import java.io.FileInputStream;
import java.io.InputStream;
public class AliOssUtil {
// Endpoint以华东1(杭州)为例,其它Region请按实际情况填写。
private static final String ENDPOINT = "XXXXXXXXXXXXXXXXXXXXXX";
// 从环境变量中获取访问凭证。运行本代码示例之前,请确保已设置环境变量OSS_ACCESS_KEY_ID和OSS_ACCESS_KEY_SECRET。
//EnvironmentVariableCredentialsProvider credentialsProvider = CredentialsProviderFactory.newEnvironmentVariableCredentialsProvider();
private static final String ACCESS_KEY_ID="XXXXXXXXXXXXXXXXXXXXXXX";
private static final String ACCESS_KEY_SECRET="XXXXXXXXXXXXXXXXXXXXXXXXXXXX";
// 填写Bucket名称,例如examplebucket。
private static final String BUCKET_NAME = "XXXXXXXXXXXXXXXXXXXXXXXXXXXX";
public static String uploadFile(String objectName,InputStream in) throws Exception {
// 创建OSSClient实例。
//OSS ossClient = new OSSClientBuilder().build(endpoint, credentialsProvider);
OSS ossClient = new OSSClientBuilder().build(ENDPOINT, ACCESS_KEY_ID,ACCESS_KEY_SECRET);
String url="";
try {
// 填写字符串。
String content = "Hello OSS,你好世界";
// 创建PutObjectRequest对象。
PutObjectRequest putObjectRequest = new PutObjectRequest(BUCKET_NAME, objectName, in);
// 如果需要上传时设置存储类型和访问权限,请参考以下示例代码。
// ObjectMetadata metadata = new ObjectMetadata();
// metadata.setHeader(OSSHeaders.OSS_STORAGE_CLASS, StorageClass.Standard.toString());
// metadata.setObjectAcl(CannedAccessControlList.Private);
// putObjectRequest.setMetadata(metadata);
// 上传字符串。
PutObjectResult result = ossClient.putObject(putObjectRequest);
url = "https://"+BUCKET_NAME+"."+ENDPOINT.substring(ENDPOINT.lastIndexOf("/")+1)+"/"+objectName;
} catch (OSSException oe) {
System.out.println("Caught an OSSException, which means your request made it to OSS, "
+ "but was rejected with an error response for some reason.");
System.out.println("Error Message:" + oe.getErrorMessage());
System.out.println("Error Code:" + oe.getErrorCode());
System.out.println("Request ID:" + oe.getRequestId());
System.out.println("Host ID:" + oe.getHostId());
} catch (ClientException ce) {
System.out.println("Caught an ClientException, which means the client encountered "
+ "a serious internal problem while trying to communicate with OSS, "
+ "such as not being able to access the network.");
System.out.println("Error Message:" + ce.getMessage());
} finally {
if (ossClient != null) {
ossClient.shutdown();
}
}
return url;
}
}
1.3 创建文件上传controller
package com.geji.controller;
import com.geji.pojo.Result;
import com.geji.utils.AliOssUtil;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import java.io.File;
import java.io.IOException;
import java.util.UUID;
@RestController
public class FileUploadController {
@PostMapping("/upload")
public Result<String> upload(MultipartFile file) throws Exception {
String originalFilename=file.getOriginalFilename();
String filename= UUID.randomUUID().toString()+originalFilename.substring(originalFilename.lastIndexOf("."));
String url= AliOssUtil.uploadFile(filename,file.getInputStream());
return Result.success(url);
}
}
