我使用JAX-RS 2.0并问自己，发送多个文本文件的最佳方式是什么。
我的客户端应用程序会创建多个文本文件，这些文本文件必须在一次运行中在我的REST服务方法中处理。
目前，我发送了对每个文本文件的请求，并等待所有文件都被发送。
我更愿意以一个数组的形式在一个请求中发送文件。有可能吗？也许有人能举个例子，这看起来怎么样？我试过自己，但我不知道要使用哪种MediaType。可以使用MediaType.TEXT_PLAIN发送单个文件。如果我使用MULTIPART_FORM_DATA，则REST服务始终抛出以下异常：

有谁能告诉我如何处理这件事。我已经在网上搜索了有用的信息，但没有找到匹配的解决方案。
最好的问候

您需要jersey-multipart扩展。有用的操作方法是http://aruld.info/handling-multiparts-in-restful-applications-using-jersey/
