Image 在服务器之间传递映像以进行远程保存

我的Spring应用程序将图像文件传递给Jersey应用程序，以摆脱所有图像处理任务

在接收图像时，Jersey应用程序应在多次操作（裁剪、调整大小等）后保存图像，并返回图像url

为此，Spring应用程序在JSP文件中具有以下表单：

<form method="POST" action="/asdf" enctype="multipart/form-data">
    <input type="file" name="fstream"></input>
    <input type="submit" value="Upload"/>
</form>

执行上述预期行动的简单方法是什么？ 如何在Spring应用程序中将其转换为BuffereImage，将其发布到Jersey应用程序，执行所需操作并保存图像

如果可以，如何将DataInputStream转换为BuffereImage

---

提前谢谢。

因为没有答案

我从提交的表单数据中获取字节数组

向REST服务器发送了一个字节为[]的对象

在服务器端，我将字节[]转换为BuffereImage，并根据需要对其进行缩放（使用ImgScalr API），然后保存它
