将多个（文本）文件发送到REST Service的正确方法是什么

Question

我使用JAX-RS 2.0并问自己，发送多个文本文件的最佳方法是什么。

我的客户端应用程序创建了多个文本文件，这些文件必须在我的REST Service方法中一次运行。

此刻，我为每个文本文件发送一个请求，并等待所有文件发送完毕。

我希望在一个请求中以数组形式发送文件。 有可能这样做吗？ 谁能给我一个例子，这看起来如何？ 我尝试过自己，但是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服务始终会引发以下异常：

谁能告诉我该如何处理。 我已经在网上搜索了有用的信息，但是没有找到匹配的解决方案。

最好的祝福

您需要jersey-multipart扩展名。 一个有用的方法是在http://aruld.info/handling-multiparts-in-restful-applications-using-jersey/
