上载文件时出现不支持的媒体类型错误(netbeans中带有jersey和java的Restfull webservices)

上载文件时出现不支持的媒体类型错误(netbeans中带有jersey和java的Restfull webservices),java,rest,jersey,Java,Rest,Jersey,为了上传文件,我创建了一个Web服务: 服务: package services; 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.w

为了上传文件,我创建了一个Web服务:

服务:

package services;

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 ServiceResource {

    @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();
        }

    }

}
我还有一个ApplicationConfig.java文件,该文件是在创建服务时生成的:

/*
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */

package services;

import java.util.Set;
import javax.ws.rs.core.Application;

/**
 *
 * @author odjansse
 */
@javax.ws.rs.ApplicationPath("webresources")
public class ApplicationConfig extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> resources = new java.util.HashSet<>();
        addRestResourceClasses(resources);
        return resources;
    }

    /**
     * Do not modify addRestResourceClasses() method.
     * It is automatically populated with
     * all resources defined in the project.
     * If required, comment out calling this method in getClasses().
     */
    private void addRestResourceClasses(Set<Class<?>> resources) {
        resources.add(services.ServiceResource.class);
    }

}
但是,当我选择上载并发送图像时,我在服务器日志中看到以下错误:

我得到的HTTP状态代码是
415不支持的媒体
。虽然我尝试上传的所有文件都有这个

它试图发布到的url为:

http://localhost:8084/FAServiceProvider/webresources/file/upload

我现在的问题是,我做错了什么,为什么这个上传不起作用

显然,我必须包括可在此处下载的mimepull jar:

您上载的文件类型是什么?我尝试了.txt文件和.mp3文件.pdf文件。所有的错误都是一样的。我怀疑它和文件本身有什么关系。我也遇到了同样的问题,我试过使用,但仍然无法解决。你能查一下吗
