文件上传端点需要关闭InputStream吗? [英] File upload endpoint need to close InputStream?

问题描述

@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Path("/upload")
public String upload(@FormDataParam("file") InputStream inputStream) {
    ...
    inputStream.close(); // necessary?
}

对于接受文件输入的API端点，我们需要手动关闭InputStream还是框架为我们完成了此任务?

For an API endpoint that accepts a file input, do we need to manually close the InputStream or does the framework do it for us?

我检查了 Jersey文档，但找不到任何文档信息.

I have checked the Jersey docs but could not find any information about it.

寻找可靠的来源或通过某种方式对其进行验证.

Looking for credible source or some way to validate it.
