找不到媒体类型 = 应用程序/八位字节流，类型 = 类 org.glassfish.jersey.media.multipart.MultiPart 的 MessageBodyWriter答案

【问题标题】：MessageBodyWriter not found for media type=application/octet-stream, type=class org.glassfish.jersey.media.multipart.MultiPart找不到媒体类型 = 应用程序/八位字节流，类型 = 类 org.glassfish.jersey.media.multipart.MultiPart 的 MessageBodyWriter

【问题描述】：

我在升级 Jersey 发行版后收到 MessageBodyProviderNotFoundException。我已经在web.xml 中注册了MultiPart，但似乎我缺少更多配置。

WebTarget webTarget = client.createResource( ESignatureSpringUtil.getMessage( KeyConstants.ALSB_DOCUSIGN_ADDRESS )
                + ESignatureSpringUtil.getMessage( KeyConstants.REST_SEND_DOCUMENTS_ADDRESS ) );

        Invocation.Builder builder = webTarget
                .path( ESignatureSpringUtil.getMessage( KeyConstants.REST_SEND_DOCUMENTS_ADDRESS ) )
                .request( MediaType.APPLICATION_XML )

                .header( DocusignRESTContants.X_DOCUSIGN_AUTHENTICATION, getDocusignAuthHeader( cu ) );

        Response response = builder.post( Entity.entity( multiPart, MediaType.APPLICATION_OCTET_STREAM ), Response.class );

【问题讨论】：

请同时显示导致此错误的代码
@peeskillet。有很多层，但代码在我试图将八位字节流作为媒体类型发送的 post 方法上失败了。

标签： java rest jersey jax-rs

【解决方案1】：

我终于让它工作了。我将表单作为 MultiPart 对象发送，无法发送多个表单。我必须将它作为字节流发送，而不仅仅是作为普通的 java 对象。 multipart.toString().getBytes() 在实体方法中。我从供应商那里收到了 200 个状态码。
