(2)完整代码 代码复制下来基本不变,只需要更改对应位位置的值,改成自己的对象存储oss的相关信息.包括: endpoint 是用来指定阿里云 OSS 服务的访问域名或URL。 更改成自己的Bucket名称例如web-3tlias。 填写Object完整路径完整路径中不能包含Bucket名称例如 String objectName 1.txt;表示存在Bucket该目录下 填写本地文件的完整路径例如D:C:\\Users\\ZJ\\Desktop\\1.txt。如果未指定本地路径则默认从示例程序所属项目对应本地路径中上传文件流。sql String filePath C:\\Users\\ZJ\\Desktop\\1.txt;

} 方式二(跟黑马最新教程同代码)
(1)在复制下来的代码中
将那个自动获取的实例删除
EnvironmentVariableCredentialsProvider credentialsProvider CredentialsProviderFactory.newEnvironmentVariableCredentialsProvider();这个实例用于获取环境变量中的凭证信息。 然后重新加入 String accessKeyId/your accessKeyId; String accessKeySecretyour accessKeySecret;然后将
OSS ossClient new OSSClientBuilder().build(endpoint, credentialsProvider);这一句改成
OSS ossClient new OSSClientBuilder().build(endpoint, accessKeyId,accessKeySecret);(2)完整代码
