用泽西2发送多部分json字符串

Question

我想编写一个上载json字符串的Java客户机。我有一个关于webservice和C++代码的描述，但这对我没有帮助。不幸的是，我在网上找到的解决方案对我不起作用。对必须使用MultiPart的webservice的描述。

• MultiPart
  • ContentDispositionHeader: form-data name = "\ObjectInfo"\
    • 一些信息
    • 更多信息
    • ……

​

- ContentDispositionHeader:  form-data name = filename  
    - File multipart data

​

​

这个描述对我没有太大帮助。在创建MultiPart时，我会遇到一个很长的异常堆栈，当我试图发布数据时，会得到一个非常长的异常堆栈。代码片段如下所示：

Client client = ClientBuilder.newBuilder()
            .register(MultiPartFeature.class)
            .build();
WebTarget target = client.target(baseUri + "/FileHandler?projectRecId="+projectRecId+"&versionRecId="+versionRecId+"&updateSchedules=true");

MultivaluedMap<String, String> info = new MultivaluedHashMap<String, String>();
info.add("FileTypeRecId", scheduleGuid);
info.add("CreatedUpdatedBy", user);
info.add("actualFileName", scheduleFileName);
info.add("MetaData","PROJECTID:" + projektIdFromJson + ";EINBAUDATUM:" + einbaudatumFromJson);

MultiPart infoPart = new MultiPart();
infoPart.contentDisposition(FormDataContentDisposition.name("ObjectInfo").build());
infoPart.bodyPart(new BodyPart().entity(info));

MultiPart filePart = new MultiPart();
filePart.contentDisposition(FormDataContentDisposition.name(scheduleFileName).build());
filePart.bodyPart(scheduleJson, MediaType.APPLICATION_JSON_TYPE);

MultiPart multiPartEntity = new MultiPart()
    .bodyPart(infoPart)
    .bodyPart(filePart);
Response response = target.request(MediaType.MULTIPART_FORM_DATA)
    .header("Authorization", "xxx")
    .post(Entity.entity(multiPartEntity, multiPartEntity.getMediaType()));

例外的明星有：

有更多的这些HK2错误，我可以提供所需的全部信息。

我现在知道我做错了什么，你们有什么想法吗？

我想你在你的项目中漏掉了下面的罐子。

1. mimepull.jar
2. jersey-multipart.jar
