通过RESTfull服务使用Jersey上载文件，并且资源配置不可修改吗？

Question

@Path("file.upload")
public class UploadFileService {
@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
        @FormDataParam("file") InputStream uploadedInputStream,
        @FormDataParam("file") FormDataContentDisposition fileDetail) {

    System.out.println("-----------------UploadFileService------------------1.");
    // Should we use a disk or DB? Decided to use DISK
    // Path should be read from properties-files
    String uploadedFileLocation = "//uploaded/" + fileDetail.getFileName();

    // save it
    writeToFile(uploadedInputStream, uploadedFileLocation);

    String output = "File uploaded to : " + uploadedFileLocation;
    // All went OK
    return Response.status(200).entity(output).build();

}

我在以下位置实施了这样的测试服务UploadFileService：

@GET
@Path("count")
@Produces("text/plain")
public String countREST() {
    return "1 one 1";
}

我得到了记录此异常：

"/webresources/file.upload/count" "GET")

环境

• Netbeans7.3.1
• 玻璃鱼4.0
• 球衣2与Glassfish 4.0

为了在Jersey应用程序中使用multipart，您需要在应用程序中注册MultiPartFeature，即：

public class ApplicationConfig extends Application {

    public Set<Class<?>> getClasses() {
        final Set<Class<?>> resources = new HashSet<Class<?>>();

        // Add your resources.
        resources.add(UploadFileService.class);

        // Add additional features such as support for Multipart.
        resources.add(MultiPartFeature.class);

        return resources;
    }
}

有关更多信息，请参阅《泽西岛用户指南》中的“
多部分”部分。

对于您面临的第二个问题，请尝试重新启动GlassFish服务器，但我不确定更改后NetBeans如何重新加载Jersey应用程序（如果这样做无济于事，请发布ApplicationConfig）。
