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！
