无法使用jersey将文件上载到rest api

Question

我的nexus公开了一个REST API来上传文件。通过curl，我可以使用以下命令上传：

卷曲-X柱“http://myurl:9086/service/rest/v1/components?repository=ebooks-store“-H”accept:application/json“-H”内容类型：multipart/form data“-F”raw。目录=测试“-F”原始。asset1=@bump。pdf；类型=应用程序/pdf“-F”原始。资产1。文件名=钢坯。pdf“

留档说只需要3个信息：https://help.sonatype.com/repomanager3/rest-and-integration-api/components-api

raw.directory (String = Destination for upload files (e.g. /path/to/files)) 
raw.assetN  (File   = at least one  Binary asset) 
raw.assetN.filename (String = Filename to be used for the corresponding assetN asset)

所以在我的java代码中，我试图用泽西做同样的事情：

FileDataBodyPart filePart = new FileDataBodyPart("file", new File("C:\\Users\\tpolo\Documents\\article.pdf"));
        FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
        FormDataMultiPart multipart = (FormDataMultiPart) formDataMultiPart
                .field("format","raw")
                .field("raw.asset1.filename","article.pdf")
                .field("raw.directory", "test")
                .field("raw.asset1","article.pdf")
                .bodyPart(filePart);

        String url = nexusBaseUrl+"v1/components?repository="+repositoryName;
        WebTarget target = client.target(url);
        //Very important to do, we have to register this
        target.register(MultiPartFeature.class);
        final Response response = target.request().post(Entity.entity(multipart, multipart.getMediaType()));

        //Use response object to verify upload success

        formDataMultiPart.close();
        multipart.close();

在我的nexus日志中，我有这个错误：

我做错了什么？当我变生的时候。资产1。文件名就是我得到的文件名

我真的不知道该怎么办。

如果你有一个maven回购协议，你似乎必须使用maven值来上传。生的对我不管用。但这对我的Maven回购协议有效。
