代碼整合oss
- pom文件引入sdk依賴
<!-- jdk1.8依賴 -->
<dependency>
<groupId>com.aliyun.oss</groupId>
<artifactId>aliyun-sdk-oss</artifactId>
<version>3.10.2</version>
</dependency>
<!--如果使用的是Java 9及以上的版本,則需要添加jaxb相關(guān)依賴。添加jaxb相關(guān)依賴示例代碼如下: -->
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.1</version>
</dependency>
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
</dependency>
<!-- no more than 2.3.3-->
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
<version>2.3.3</version>
</dependency>

#bucket可以在控制臺(tái)創(chuàng)建,也可以使用java代碼創(chuàng)建

- 創(chuàng)建config類讀取配置信息
import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
/**
* 常量類,讀取配置文件application.properties中的配置
*/
@Component
public class ConstantPropertiesUtil implements InitializingBean {
@Value("${aliyun.oss.file.endpoint}")
private String endpoint;
@Value("${aliyun.oss.file.keyid}")
private String keyId;
@Value("${aliyun.oss.file.keysecret}")
private String keySecret;
@Value("${aliyun.oss.file.bucketname}")
private String bucketName;
public static String END_POINT;
public static String ACCESS_KEY_ID;
public static String ACCESS_KEY_SECRET;
public static String BUCKET_NAME;
@Override
public void afterPropertiesSet() throws Exception {
END_POINT = endpoint;
ACCESS_KEY_ID = keyId;
ACCESS_KEY_SECRET = keySecret;
BUCKET_NAME = bucketName;
}
}
- 創(chuàng)建controller類,上傳文件接口
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;
@Api(description="阿里云文件管理")
@CrossOrigin //跨域
@RestController
@RequestMapping("/oss/file")
public class FileController {
@Autowired
private FileService fileService;
/**
* 文件上傳
*
* @param file
*/
@ApiOperation(value = "文件上傳")
@PostMapping("upload")
public R upload(
@ApiParam(name = "file", value = "文件", required = true)
@RequestParam("file") MultipartFile file) {
String uploadUrl = fileService.upload(file);
//返回r對(duì)象
return R.ok().message("文件上傳成功").data("url", uploadUrl);
}
}
- 創(chuàng)建service接口
import org.springframework.web.multipart.MultipartFile;
public interface FileService {
/**
* 文件上傳至阿里云
* @param file
* @return
*/
String upload(MultipartFile file);
}
- 創(chuàng)建serviceImpl類實(shí)現(xiàn)接口方法
import org.joda.time.DateTime;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;
import java.io.IOException;
import java.io.InputStream;
import java.util.UUID;
@Service
public class FileServiceImpl implements FileService {
@Override
public String upload(MultipartFile file) {
//獲取阿里云存儲(chǔ)相關(guān)常量
String endPoint = ConstantPropertiesUtil.END_POINT;
String accessKeyId = ConstantPropertiesUtil.ACCESS_KEY_ID;
String accessKeySecret = ConstantPropertiesUtil.ACCESS_KEY_SECRET;
String bucketName = ConstantPropertiesUtil.BUCKET_NAME;
String uploadUrl = null;
try {
//判斷oss實(shí)例是否存在:如果不存在則創(chuàng)建,如果存在則獲取
OSSClient ossClient = new OSSClient(endPoint, accessKeyId, accessKeySecret);
if (!ossClient.doesBucketExist(bucketName)) {
//創(chuàng)建bucket
ossClient.createBucket(bucketName);
//設(shè)置oss實(shí)例的訪問權(quán)限:公共讀
ossClient.setBucketAcl(bucketName, CannedAccessControlList.PublicRead);
}
//獲取上傳文件流
InputStream inputStream = file.getInputStream();
/*
* 此處對(duì)文件進(jìn)行日期加uuid重命名,解決用戶上傳重復(fù)名文件覆蓋問題
*構(gòu)建日期路徑:avatar/2019/02/26/文件名
* new DateTime()引入了一個(gè)org.joda.time的jar
* 此處報(bào)錯(cuò)的朋友可以使用 SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd") 制定日期輸出格式
* */
String filePath = new DateTime().toString("yyyy/MM/dd");
//文件名:uuid.擴(kuò)展名
String original = file.getOriginalFilename();
String fileName = UUID.randomUUID().toString().replace("-","");
String fileType = original.substring(original.lastIndexOf("."));
String newName = fileName + fileType;
String fileUrl = filePath + "/" + newName;
//文件上傳至阿里云
ossClient.putObject(bucketName, fileUrl, inputStream);
// 關(guān)閉OSSClient。
ossClient.shutdown();
//獲取url地址
uploadUrl = "https://" + bucketName + "." + endPoint + "/" + fileUrl;
} catch (IOException e) {
e.printStackTrace();
}
return uploadUrl;
}
}
-
swagger進(jìn)行上傳測(cè)試
至此oss上傳文件整合完畢
