Can't find @FormDataParam in Jersey 2.17
提问by Rasa
I'm quite new to web services so I've started with basic examples. This one relates to file upload. I'm using latest (2.17) version of Jersey bundle for non-maven developers. It states that:
我对 Web 服务很陌生，所以我从基本示例开始。这一项与文件上传有关。我正在为非 Maven 开发人员使用最新 (2.17) 版本的 Jersey 包。它指出：
bundle contains the JAX-RS 2.0 API jar, all the core Jersey module jars as well as all the required 3rd-party dependencies
bundle 包含 JAX-RS 2.0 API jar、所有核心 Jersey 模块 jar 以及所有必需的第 3 方依赖项
. The problem is that I can not compile this part:
. 问题是我无法编译这部分：
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = "d://uploaded/" + fileDetail.getFileName();
// save it
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded to : " + uploadedFileLocation;
return Response.status(200).entity(output).build();
}
It seems that @FormDataParamdoesn't exist in Jersey 2.17 bundle although docs says it does. Is the 2.17 bundle incomplete? How can I resolve this problem?
@FormDataParam尽管文档说它确实存在，但 Jersey 2.17 包中似乎不存在。2.17 捆绑包不完整吗？我该如何解决这个问题？

The bundle only includes the the core modules (and their dependencies). Unfortunately, Multipart is not part of the core. You'll need this dependency(Maven) also
该包仅包含核心模块（及其依赖项）。不幸的是，Multipart 不是核心的一部分。您还需要此依赖项（Maven）
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.17</version>
</dependency
If you're not using Maven, from what I can tell, this artifact only has one other dependency (that is not already included in the bundle), and it's mimepull-1.9.3.
如果您没有使用 Maven，据我所知，这个工件只有一个其他依赖项（尚未包含在捆绑包中），并且它是mimepull-1.9.3.
You can download both artifacts below
