找不到类 com.sun.jersey.core.header.FormDataContentDisposition，

我有一个球衣服务器和客户端。我已经尝试了几乎所有方法，但我无法将文件从客户端发送到服务器。我从服务器端使用此方法：

@Path("/" + PathConstants.UPLOAD_RESOURCE)
public class UploadResource {
    @POST
    @Consumes({ MediaType.MULTIPART_FORM_DATA, 
    MediaType.APPLICATION_OCTET_STREAM, MediaType.MULTIPART_FORM_DATA })
    public Response uploadFile(@FormDataParam("file") InputStream 
         uploadedInputStream,
            @FormDataParam("file") FormDataContentDisposition fileDetail) {
         String uploadedFileLocation = "C:\Users\Desktop\" + 
         fileDetail.getFileName();
         System.out.println(uploadedFileLocation);
         File objFile = new File(uploadedFileLocation);
         if (objFile.exists()) {
            objFile.delete();
        }
        saveToFile(uploadedInputStream, uploadedFileLocation);
        String output = "File uploaded via Jersey based RESTFul Webservice to: " 
        + uploadedFileLocation;
        return Response.status(200).entity(output).build();
    }
private void saveToFile(InputStream uploadedInputStream, String uploadedFileLocation) {
        try {
            OutputStream out = null;
            int read = 0;
            byte[] bytes = new byte[1024];
            out = new FileOutputStream(new File(uploadedFileLocation));
            while ((read = uploadedInputStream.read(bytes)) != -1) {
                out.write(bytes, 0, read);
            }
            out.flush();
            out.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

谁能告诉我我错在哪里，因为我试图弄清楚几天，但我仍然无法让它工作。

基本上，

你的后端代码是正确的。在"消费"中粗鲁地对待不必要的东西。您只需要多部分表单数据。

@Consumes( MediaType.MULTIPART_FORM_DATA )

我怀疑问题出在客户端或依赖项上。因此，客户端应如下所示：

public void testUploading() {
        File file = new File("C:\your_test_file_to_upload.jpg");
        FileDataBodyPart fileDataPart = new FileDataBodyPart("file", file, MediaType.APPLICATION_OCTET_STREAM_TYPE);
        try (FormDataMultiPart formDataMultiPart = new FormDataMultiPart()) {
                MultiPart multipartEntity = formDataMultiPart.bodyPart(fileDataPart);
                Client client = ClientBuilder.newBuilder().register(MultiPartFeature.class).build();
                Response response = client.target("/" + PathConstants.UPLOAD_RESOURCE)
                        .request()
                        .post(Entity.entity(multipartEntity, MediaType.MULTIPART_FORM_DATA));
        }
}

检查在服务器和客户端上注册的MultiPartFeature(我在示例中为您做了(两者。此外，看起来您使用的是旧泽西岛，请考虑更新到jersey-media-multipart<</p>

我也忘了提到我正在使用 HttpBasicAuthentication 的客户端代码，以便服务器可以对发送请求的用户进行身份验证如果我将客户端修改为您建议的版本，如何对用户进行身份验证。看看客户端代码：

public class UploadCommand implements Command {
@Override
public void execute(CommandArgument arguments) {
    File file = new File("C:\addfile.txt");
    final ClientConfig config = new DefaultClientConfig();
    final Client client = Client.create(config);
    client.addFilter(new LoggingFilter());
    client.addFilter(
            new HTTPBasicAuthFilter(CommandLineRestClient.currentUsername, CommandLineRestClient.currentPassword));
    WebResource resource = client.resource(PathConstants.UPLOAD_FILE);
    FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
    formDataMultiPart.bodyPart(new FileDataBodyPart("file", file, MediaType.APPLICATION_OCTET_STREAM_TYPE));
    ClientResponse response = resource.type(MediaType.MULTIPART_FORM_DATA).post(ClientResponse.class,
            formDataMultiPart);
    System.out.println("Response: " + response.getStatus());
}
