Jersey客戶端多部分/表單數據消息正文編寫器異常

Question

我覺得我非常接近，但在這里錯過了一塊拼圖。 我得到一個關於消息體編寫器的例外。 任何幫助表示贊賞。

服務器端代碼

@POST
@Path("/{id}/documents")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public Response uploadAndAddNewDocument(
    @FormDataParam("file") final InputStream fileInputStream,
    @FormDataParam("file") final FormDataContentDisposition fileDetail,
    @FormDataParam("file") final FormDataBodyPart fileBodyPart, 
    @FormDataParam("model") final SomeModel model,
    @FormDataParam("model") final FormDataBodyPart modelBodyPart) throws WebApplicationException {

    // Here model is received as application/json
    // Code to process model and uploaded file
    // This works when posted using POSTMAN
}

服務器代碼使用以下POSTMAN請求

POST /someresource/123/documents HTTP/1.1
Host: localhost:8080
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
Cache-Control: no-cache
Postman-Token: c6425906-1b1f-39d0-bed6-93db9e9a6ad9

----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="report.xml"
Content-Type: application/xml

<root></root>

----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="doc"
Content-Type: application/json

{}
----WebKitFormBoundary7MA4YWxkTrZu0gW

澤西客戶代碼

//Client configuration code
config.getClasses().add(MultiPartWriter.class);

//Client call to server
    FormDataMultiPart multiPartFormData = new FormDataMultiPart();
    multiPartFormData.bodyPart(new BodyPart("doc", MediaType.APPLICATION_JSON_TYPE));
    multiPartFormData.bodyPart(new FileDataBodyPart("file", uploadFile));
    return service.path(uri).type(MediaType.MULTIPART_FORM_DATA).post(SomeModel.class, multiPartFormData);

你需要檢查的東西很少

將mimepull.jar添加到您的lib或Maven

<dependency> <groupId>org.jvnet.mimepull</groupId> <artifactId>mimepull</artifactId> <version>1.9.5</version> </dependency>

如果您正在處理文件，請確保在標題處發送content-length content-type accept-encoding
