java - jersey 2.x 中的 Multipart：java 客户端找不到内容类型 multipart/form-data 类型的编写器

Question

我有一个jersey 1.x依赖项的项目。我决定将它升级到jersey 2.x并更改所有引用 jersey 1.x 的依赖项。

在没有得到特定错误的情况下，无论我进行什么更改，我都会收到由以下原因引起的 javax.ws.rs.ProcessingException 消息：

Caused by: javax.ws.rs.ProcessingException: could not find writer for content-type multipart/form-data type: org.glassfish.jersey.media.multipart.MultiPart

错误所指的代码行如下所示：

//final ClientConfig config = new ClientConfig();
        final Client client = ClientBuilder.newClient();
        //client.addFilter(new LoggingFilter(System.out));
        final WebTarget target = client.target(urlString);
        MultiPart multiPart = new MultiPart();
         multiPart.setMediaType(MediaType.MULTIPART_FORM_DATA_TYPE);
        //multiPart.bodyPart(new BodyPart(inParams.toString(), MediaType.TEXT_PLAIN_TYPE));
        if(mode==CALL_INSERT_DOC){
            //final File fileToUpload = new File(filePath);
            FileDataBodyPart fileDataBodyPart = new FileDataBodyPart("file",
                    new File(filePath),
                    MediaType.APPLICATION_OCTET_STREAM_TYPE);
                multiPart.bodyPart(fileDataBodyPart);
            //multiPart.bodyPart(new BodyPart(fileToUpload, MediaType.MULTIPART_FORM_DATA_TYPE));// APPLICATION_OCTET_STREAM_TYPE
        }


        // POST the request
        Response clientResp = target.request(MediaType.APPLICATION_JSON_TYPE)
                .post(Entity.entity(multiPart, multiPart.getMediaType()));
        //final Response clientResp =target.request().post(Entity.entity(multiPart, MediaType.MULTIPART_FORM_DATA));

        System.out.println("Response: " + clientResp.getStatus());
        JSONObject response = clientResp.readEntity(JSONObject.class);
        System.out.println(response);

        client.close();

这是我的pom.xml：

我有不同类型的可能解决方案，但我无法弄清楚确切的问题是什么。

是依赖项之间的某种冲突吗？有什么遗漏吗？

我想知道 jersey 2 .x 是否不完全支持 multipart （至少不是我认为的方式），因为我找不到任何文档。

即使是线索或寻找的地方也会非常有帮助。
