    public String uploadImg(String bucketName,String key, InputStream resources, long length , String contentType) {

        ObjectMetadata objectMeta = new ObjectMetadata();

        objectMeta.setContentLength(length);

        objectMeta.setContentType(contentType);

        PutObjectResult putObject = OSSclient.putObject(bucketName, key, resources, objectMeta);

        return putObject.getETag();

    }

 public String saveImgFileToAliyun(File avatarFile){

        contentType = "image/jpeg";

        FileInputStream fileInputStream;

        try {

            fileInputStream = new FileInputStream(avatarFile);

            byte[] byteArrayFile = IOUtils.toByteArray(fileInputStream);

            ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArrayFile);

            String md5 = Md5Util.getMd5String(byteArrayFile);

            // check if file exists

            boolean isExists = checkIfFileExists("xxx", md5);

            if (isExists) {

                return md5;

            }else{

                String etag = uploadImg("xxx", md5,byteArrayInputStream,avatarFile.length(), contentType);

                if (etag.equalsIgnoreCase(md5)) {

                    return etag;

                }

            }

        } catch (FileNotFoundException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        }

        return "";

    }

   public static  byte[] input2byte(InputStream inStream)

            throws IOException {

        ByteArrayOutputStream swapStream = new ByteArrayOutputStream();

        byte[] buff = new byte[100];

        int rc = 0;

        while ((rc = inStream.read(buff, 0, 100)) > 0) {

            swapStream.write(buff, 0, rc);

        }

        byte[] in2b = swapStream.toByteArray();

        return in2b;

    }

 当时由于调用 :byte[] byteArrayFile = IOUtils.toByteArray(fileInputStream); 
 拿到byte数组去算md5的值，所以就调用了  input2byte方法，红色标红部分把文件流 fileInputStream 的offset指针，指到了文件的末尾.

 因为我之前上传部分代码写得是： String etag = uploadImg("xxx", md5,fileInputStream,avatarFile.length(), contentType);
 文件流指针在末尾，所以当上传时再次读取这个流对象 fileInputStream的时候文件没有读取到内容，直接导致了 read time out!
后来，解决的方法是再次用byte 数组创建一个流对象，并传递到uploadImg 方法中：

  ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArrayFile);

这问题昨天困扰我到凌晨1点半，第二天，去公司问同事李航人称航哥之后解决。在这里感谢下航哥！
