获取OSSClient
    public static OSSClient getOSSClient() {
        OSSClientBuilder clientBuilder = new OSSClientBuilder();
        return (OSSClient) clientBuilder.build(endPoint, accessKeyId, accessKeySecret);
    }

文件下载
    public static ObjectMetadata downloadByOOSClient(Student student, OSSClient ossClient){

        String objectName = folder + student.getName();
        String path = objectName + ".jpeg";
        String bucket = bucketName;
        try {
            return ossClient.getObject(new GetObjectRequest(bucket, path), new File(path));
        } catch (Exception e){
            e.printStackTrace();
            logger.info("下载出错：{}", e.getMessage());
        }
        return null;
    }

说你下载时输入的key不存在，这个key 就是你上传是输出的key,对应的是Object Name.
你这个getObject输的参数怎么和我看的官方文档不一样呢？
```
// 下载OSS文件到本地文件。如果指定的本地文件存在会覆盖，不存在则新建。ossClient.getObject(new GetObjectRequest(bucketName, objectName), new File("<yourLocalFile>"));
```
