Springboot集成阿里云OSS对象存储功能

首先登录阿里云账号

到控制台里选择对象存储OSS，开通oss，注意此服务会根据流量收取费用

点击Access Key按要求创建进行，

记下AccessKey  和Accesssecret

在项目里添加阿里云的依赖

   com.aliyun.oss
   aliyun-sdk-oss
   2.4.0


   commons-fileupload
   commons-fileupload
   1.3.1

application.yml详细的配置文件

oos:
   endpoint: oss-cn-shanghai.aliyuncs.com
   keyid:    xxxxxxxx # 填写刚刚生成的AccessKey
   keysecret: xxxxxxx  # 填写刚刚生成的Accesssecret
   bucketname: 2019131 # bucket名称
   filehost: 11111    #bucket下文件夹的路径

endpoint是根据你新建申请bucket地域选择的，点击+号

新建完bucket点击你的bucket、

外网访问里找到endpoint

 

下面是详细代码

获取application.yml配置的ConstantProperties类

import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Data
@Component
@ConfigurationProperties(prefix = "oos")
public class ConstantProperties {
    private  String endpoint;
    private  String keyid;
    private  String keysecret;
    private  String bucketname;
    private  String filehost;
}

上传，获取文件列表，删除的util类

@Service
@Slf4j
public class AliyunOSSUtil {
    @Autowired
    private  ConstantProperties constantProperties;
    private static SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");

    /**
     * 上传
     * @param file
     * @return
     */
    public  String upload(File file){
        log.info("=========>OSS文件上传开始："+file.getName());
        String endpoint= constantProperties.getEndpoint();
        String accessKeyId= constantProperties.getKeyid();
        String accessKeySecret=constantProperties.getKeysecret();
        String bucketName=constantProperties.getBucketname();
        String fileHost=constantProperties.getFilehost();
        System.out.println(endpoint+"endpoint");
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
        String dateStr = format.format(new Date());

        if(null == file){
            return null;
        }

        OSSClient ossClient = new OSSClient(endpoint,accessKeyId,accessKeySecret);
        try {
            //容器不存在，就创建
            if(! ossClient.doesBucketExist(bucketName)){
                ossClient.createBucket(bucketName);
                CreateBucketRequest createBucketRequest = new CreateBucketRequest(bucketName);
                createBucketRequest.setCannedACL(CannedAccessControlList.PublicRead);
                ossClient.createBucket(createBucketRequest);
            }
            //创建文件路径
            String fileUrl = fileHost+"/"+(dateStr + "/" + UUID.randomUUID().toString().replace("-","")+"-"+file.getName());
            //上传文件
            PutObjectResult result = ossClient.putObject(new PutObjectRequest(bucketName, fileUrl, file));
            //设置权限 这里是公开读
            ossClient.setBucketAcl(bucketName,CannedAccessControlList.PublicRead);
            if(null != result){
                log.info("==========>OSS文件上传成功,OSS地址："+fileUrl);
                return fileUrl;
            }
        }catch (OSSException oe){
            log.error(oe.getMessage());
        }catch (ClientException ce){
            log.error(ce.getMessage());
        }finally {
            //关闭
            ossClient.shutdown();
        }
        return null;
    }

controller类

@Controller
@RequestMapping("/oss")
@Slf4j
public class UploadController {
    @Autowired
    private AliyunOSSUtil aliyunOSSUtil;
    @Autowired
    private  ConstantProperties constantProperties;
    @GetMapping("/toUploadBlog")
    public String toUploadBlog(){
        return "oss/upload";
    }
   
    @PostMapping("/toUploadBlog")
    public String toUploadBlogPost(MultipartFile file){
        log.info("=========>文件上传");
        try {

            if(null != file){
                String filename = file.getOriginalFilename();
                if(!"".equals(filename.trim())){
                    File newFile = new File(filename);
                    FileOutputStream os = new FileOutputStream(newFile);
                    os.write(file.getBytes());
                    os.close();
                    file.transferTo(newFile);
                    //上传到OSS
                    String uploadUrl = aliyunOSSUtil.upload(newFile);

                }

            }
        }catch (Exception ex){
            ex.printStackTrace();
        }
        return "oss/index";
    }

    @GetMapping("/getObjectList")
    @ResponseBody
    public List getObjectList(){
        String bucketName=constantProperties.getBucketname();
        System.out.println(bucketName);
        List objectList = aliyunOSSUtil.getObjectList(bucketName);
        return objectList;
    }
    

@GetMapping("/delete")
@ResponseBody
public String deleteBlog(@RequestParam("key")String key){
    aliyunOSSUtil.deleteBlog(key);
    return "删除成功";

templates/oss下的html,这里我用了thymeleaf

index.html

    
    


HELLO,THIS IS OSS
上传成功

选择文件上传

打开阿里云控制台，点击bucket->文件管理

在2019131下的11111文件夹下看到刚刚上传的图片
