Question

我们正在尝试开发一种接受分段文件上传的REST服务。

我进行了以下更改：

dependencies.gradle:
compile('jersey-multipart:1.2')

web.xml:
<init-param>
    <param-name>jersey.config.server.provider.classnames</param-name>
    <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
</init-param>

WADL changes:
<resource path="/upload">
  <method name="POST" id="upload" resource-operation="POST /upload">
    <request>                                                               
       <representation mediaType="multipart/form-data" />                                                                                                                                                 
    </request>
    <response status="200">                                                                                
      <representation element="n:Response" mediaType="application/xml"/>
    </response>
  </method>
</resource>

Java:
 @POST
 @Path("/upload")
 @Consumes(MediaType.MULTIPART_FORM_DATA)
 @Produces("application/xml")
 public Response uploadMethod(FormDataMultiPart file) throws FileNotFoundException {
        <>some code here.....<> }

在POSTMAN的“正文”中，我们选择“表单数据”选项，然后将pdf文件上传到键值对的值部分。

当我用POSTMAN发出此请求时，出现以下错误：

Caused By: org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException: MessageBodyWriter not found for media type=multipart/form-data
....
....

请让我知道解决此问题所需的更改。
