oss图片文件旋转处理。

这个是生成缩略图的java代码，你将endpoint、bucket等设置成你实际的值就可以了

@Test
   public void testPutAndGet() {
      final String OSS_ENDPOINT = "oss-cn-beijing.aliyuncs.com";
      final String IMG_ENDPOINT = "img-cn-beijing.aliyuncs.com";
       final String ACCESS_KEY_ID = "** Provide your access key id **";
       final String ACCESS_KEY_SECRET = "** Provide your access key id **";;
      
       String bucketName = "jy-bj-img";
       String key = "example.jpg";
       String filePath = "D:\\pic\\example.jpg";
       String downloadPath = "D:\\pic\\ example@100w.jpg";
      
       try {  
          OSSClient client4oss = new OSSClient(OSS_ENDPOINT, ACCESS_KEY_ID, ACCESS_KEY_SECRET);
          client4oss.putObject(bucketName, key, new File(filePath));
          System.out.println("upload " + key + " succeed");
          
          OSSClient client4img = new OSSClient(IMG_ENDPOINT, ACCESS_KEY_ID, ACCESS_KEY_SECRET);
          GetObjectRequest getObjectRequest = new GetObjectRequest(bucketName, key + "@100w");
          client4img.getObject(getObjectRequest, new File(downloadPath));
          System.out.println("down " + key + "@100 succeed");
       } catch (OSSException oe) {
          System.out.println(oe.getMessage());
       } catch (Exception e) {
          System.out.println(e.getMessage());
       }
   }

怎么弄图片缩略参数，求代码例子 java的

目前图片处理服务是不支持回存到OSS的Bucket中的，但你可以下载后再上传到OSS的bucket中。图片服务的持久化支持，听说在开发计划中了
