Question

我的JAX-Rs网络服务程序不支持媒体类型错误我正在关注网址：http://www.mkyong.com/webservices/jax-rs/file-upload-example-in-jersey/
我运行程序并尝试上传.jpg文件显示错误：媒体类型不支持。我使用jersey-multipart-1.17.1.jar进行多部分数据支持任何身体帮助我尝试了所有。

我的WebService计划是：

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.sun.jersey.core.header.FormDataContentDisposition;
import com.sun.jersey.multipart.FormDataParam;

@Path("/file")

public class UploadFileService {


    @POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)

    public Response uploadFile(

        @FormDataParam("file") InputStream uploadedInputStream,
        @FormDataParam("file") FormDataContentDisposition fileDetail) {

        String uploadedFileLocation = "c://" + fileDetail.getFileName();

        // save it
        writeToFile(uploadedInputStream, uploadedFileLocation);

        String output = "File uploaded to : " + uploadedFileLocation;

        return Response.status(200).entity(output).build();

    }

    // save uploaded file to new location
    private void writeToFile(InputStream uploadedInputStream,
        String uploadedFileLocation) {

        try {
            OutputStream out = new FileOutputStream(new File(
                    uploadedFileLocation));

            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();
        }

    }

}

web.xml文件是
