阿里云对象存储OSS图片上传并回显

       
        
            com.aliyun.oss
            aliyun-sdk-oss
            2.8.2
        

只是练习所以实现代码直接写在了controller里

import com.aliyun.oss.OSSClient;
import com.aliyun.oss.model.PutObjectRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.multipart.MultipartFile;

import java.io.InputStream;
import java.util.UUID;

@Controller
public class OssController {
    
    public static String ENDPOINT = "";
    public static String ACCESSKEYID = "";
    public static String ACCESSKEYSECRET = "";
    public static String BUCKETNAME = "";
    public static String PATH = "/";
    
    @RequestMapping(value = "/upload")
    public String myphotoupload(MultipartFile file , Model model) {

        try {
            // 创建OSS实例
            OSSClient ossClient = new OSSClient(ENDPOINT, ACCESSKEYID, ACCESSKEYSECRET);
            // 获取上传的文件的输入流
            InputStream inputStream = file.getInputStream();
            // 获取文件名称
            String fileName = file.getOriginalFilename();

            // 在文件名称里面添加随机唯一值，使用UUID生成  把uuid生成里的-去掉
            String uuid = UUID.randomUUID().toString().replaceAll("-", "");
            fileName = uuid + fileName;
			// 拼接fileName  PATH是oss文件夹
            fileName = PATH + fileName;
            
            
            
            //ossClient.putObject(BUCKETNAME, fileName, inputStream);   用这种方式putObject上传，拼接的url是下载！！！
            //ossClient.shutdown();

            PutObjectRequest putObjectRequest = new PutObjectRequest(BUCKETNAME, fileName, inputStream);
            ossClient.putObject(putObjectRequest);
            // 关闭ossClient
            ossClient.shutdown();
            // 把上传到oss的路径返回
            // 需要将路径手动拼接出来，https://xxxxxx.oss-cn-shanghai.aliyuncs.com/edu/avatar/girl.jpg
            String url = "https://"+ BUCKETNAME + "." + ENDPOINT + "/" + fileName;
            System.out.println(url);
            model.addAttribute("url", url);
            return "demo";//demo.html
        } catch (Exception e) {
            e.printStackTrace();
            model.addAttribute("url","");
            return "demo";
        }

    }

}
