无法使用jersey 2上载文件。错误400

Question

开始时，我可以通过以下curl请求上传我的文件：

curl-u“admin:admin”-X POSThttp://myurlu: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“

通过成功的日志：

2019-08-27 17:27:40734 0000信息[qtp969575574-10357]管理组织。索纳型。关系存储库。上载内部的UploadManagerImpl-上传带有参数的组件：repository=“ebooks store”format=“raw”directory=“test”2019-08-27 17:27:40734 0000信息[qtp969575574-10357]管理组织。索纳型。关系存储库。上载内部的UploadManagerImpl-参数为file=“bulle.pdf”filename=“bulle.pdf”的资产

我的代码中有要上传的用例，所以我使用jersey创建了这个服务：

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

        String url = nexusBaseUrl+"v1/components?repository="+repositoryName;
        webTarget = client.target(url);
        //Very important to do, we have to register this
        webTarget.register(MultiPartFeature.class);
        final Response response = webTarget.request().header(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON).header("Expect", "100-continue")
                .post(Entity.entity(multipart, multipart.getMediaType()));

        //Use response object to verify upload success

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

但是我每次都有这个错误：

2019-08-27 17:28:29,617 0000INFO[qtp969575574-10306]adminorg.sonatype.nexus.repository.upload.internal.UploadManagerImpl-上传组件与参数：仓库="电子书存储"格式="原始"asset1.filename.="article.pdf"目录="测试"2019-08-27 17:28:29,618 0000INFO[qtp969575574-10306]adminorg.sonatype.nexus.repository.upload.internal.UploadManagerImpl-资产与参数：file="article.pdf"2019-08-27 17:28:29,619 0000WARN[qtp969575574-10306]adminorg.sonatype.nexus.siesta.internal.ValidationErrorsExceptionMapper-（ID c6a95618-aed1-45e8-90ee-2af315eb209b）响应：[400]'[ValidationErrorXO{id='asset1.filename.'，消息='未知组件字段'asset1.filename.}，ValidationErrorXO{id='filename'，消息='缺少所需的资产字段'Filename'on'1''}]'; 映射自：org.sonatype.nexus.rest.ValidationErrs异常：未知的组件字段'asset1.filename.'，缺少所需的资产字段'文件名'在'1'

我的代码有什么问题？我使用的webservice正在等待3个参数：

未经加工的原始目录字符串。资产文件原始。资产。文件名字符串

正确答案是

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

        String url = nexusBaseUrl+"v1/components?repository="+repositoryName;
        webTarget = client.target(url);
        //Very important to do, we have to register this
        webTarget.register(MultiPartFeature.class);
        final Response response = webTarget.request().header(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON).header("Expect", "100-continue")
                .post(Entity.entity(multipart, multipart.getMediaType()));

        //Use response object to verify upload success

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