您可以创建S3Client，用于管理存储空间和文件等OSS资源。使用Java SDK发起OSS请求，您需要使用您的AccessKey和SecretKey初始化一个S3Client，并根据需要修改ClientConfig的默认配置项。
请先阅读“基本概念-访问域名”部分，理解Endpoint相关的概念。
要接入京东云OSS，需要拥有一对有效的Access Key(包括AccessKeyId和AccessKeySecretID)进行签名认证。可以通过如下步骤获得：
获取AccessKeyId和secretAccessKeyId之后，您便可以按照以下步骤进行初始化。
下面为创建client的例子，更多Java SDK示例请访问京东云兼容S3 Java SDK示例
