gsutil is not distributed as a library, only as a command-line tool. gsutil不作为库分发，而仅作为命令行工具分发。 I don't know of a Java library that supports parallel uploads, though that doesn't mean there isn't one. 我不知道一个支持并行上传的Java库，尽管这并不意味着没有。 However, you could do parallel writes by using the Compose operation, using the JSON or XML API for Google Cloud Storage. 但是，您可以使用Compose操作（针对Google Cloud Storage的JSON或XML API）进行并行写入。 Specifically, you would write a number of smaller objects in parallel and then (once all of those objects have been written) call the Compose request to compose them into one larger object. 具体来说，您将并行编写许多较小的对象，然后（一旦所有这些对象都被写入）调用Compose请求将它们组合成一个较大的对象。 If you're using the JSON API the compose documentation is at https://cloud.google.com/storage/docs/json_api/v1/objects/compose If you're using the XML API the compose documentation is at https://cloud.google.com/storage/docs/reference-methods#putobject (see the compose query parameter). 如果您使用JSON API，则撰写文档位于https://cloud.google.com/storage/docs/json_api/v1/objects/compose；如果您使用的是XML API，则撰写文档位于https：// /cloud.google.com/storage/docs/reference-methods#putobject （请参阅compose查询参数）。
