Question

我试图创建一个球衣客户端来上传文件。我有一个网络服务和客户端。但我每次都得到415 - 不支持的媒体类型，我不知道问题是什么。我搜索了i-net / stackoverflow，但我无法找到适合我的问题的解决方案。我尝试了很多解决方案但没有成功。您可以在我的代码中将其视为注释。

客户端：

private static void clientFileUpload() throws IOException {
    ClientConfig config = new ClientConfig();
    Client client       = ClientBuilder.newClient(config);
    client.register(MultiPartFeature.class);

    URI baseUri            = UriBuilder.fromUri("http://localhost:8080/vogella.jersey.first").build();
    final WebTarget target = client.target(baseUri);

    final FileDataBodyPart filepart           = new FileDataBodyPart("files", new File("C:/Users/admin/Downloads/testtext.txt"));
    final FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
    final FormDataMultiPart multiPart         = (FormDataMultiPart) formDataMultiPart.field("foo", "bar").bodyPart(filepart);
    multiPart.setMediaType(MediaType.MULTIPART_FORM_DATA_TYPE);
    Response response = target.path("rest").path("hello").path("upload")
                              .request()
                              .header("Content-Type", MediaType.MULTIPART_FORM_DATA)  
                              .post(Entity.entity(multiPart, multiPart.getMediaType()));
    //.header("Content-Type", "multipart/form-data"
    //.header("Content-Type", "multipart/form-data;charset=UTF-8")
    //multiPart.getMediaType()
    //"Content-Tpye: multipart/form-data"
    System.out.println("--> " + response.getMediaType());
    System.out.println("--> " + response.getStringHeaders());

    System.out.println(":: RESPONSE : " + response);
    System.out.println(":: STATUSCODE: " + response.getStatus() + " -- Reason: " + response.getStatusInfo());
    String output = response.readEntity(String.class);      
    System.out.println(":: OUTPUT: " + output);

}

的WebService：我尝试了两种不同的解决方案，但我找不到我的错误。

package vogella.jersey.first;

    return new MyBean("Hello MyBean", 42);
}

@POST
@Path("/test")

public String postMyBean(MyBean myBean) {
    return myBean.anyString;
}

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
//@Produces("multipart/mixed")
public MultiPart post (final FormDataMultiPart multiPart) {
    System.out.println("::: THIS IS THE MULTIPART MESSAGE: " + multiPart);
    return multiPart;
}

@POST
@Path("/ul")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces("text/plain")
public Response uploadFile(final FormDataMultiPart form) {
    String output = "Done";
    return Response.status(200).entity(output).build();
}
}

Jersey REST files

我能够向服务器发送正常的GET和Post Request。但我也需要发送文件。我希望，有人可以帮助我。

这是我的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
