Question

我想使用Jersey（2.22.2）和＆amp ;;建立对fileupload的支持。 JAXRS。

这是我的申请：

@ApplicationPath("rest")
public class DsmJaxRsApplication extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> classes = new HashSet<>();

        classes.add(FileUploadResource.class);
        classes.add(MultiPartFeature.class);

        return classes;
    }
}

这是拦截POST请求的资源方法：

@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.TEXT_PLAIN)
@Path("upload")
public Response uploadImportFile(@FormDataParam("reason") String reason,
                                 @FormDataParam("fileName") String fileName,
                                 @FormDataParam("file") InputStream fileContent) {
    checkCreateBulkChangeAllowed();

    return Response.ok().build();
}

这是我的请求有效载荷：

------WebKitFormBoundaryAh9J98cKgsOv6WCr
Content-Disposition: form-data; name="reason"

wwwww
------WebKitFormBoundaryAh9J98cKgsOv6WCr
Content-Disposition: form-data; name="fileName"

DSM_CH_Bulk_new.xlsx
------WebKitFormBoundaryAh9J98cKgsOv6WCr
Content-Disposition: form-data; name="file"; filename="DSM_CH_Bulk_new.xlsx"
Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet


------WebKitFormBoundaryAh9J98cKgsOv6WCr--

问题是在方法内部，fileContent和reason都包含“wwww”，原因应该是fileName，null始终是let baseURL = "https://api.instagram.com/v1/tags/nofilter/media/recent?access_token=1234567.d7e73cc.cces4f9532ba442529270d698fb173cc" let popularEndpoint = "media/popular" let clientID = "d5e23bhb23414e569480724305d3f104"。有谁知道我做错了什么或我在这里错过了什么？

我的配置基于web.xml文件。尝试添加 FormDataContentDisposition 的

@POST
@Path("upload/file")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public Response uploadInspectionFile(@FormDataParam("file") InputStream inputStream,
        @FormDataParam("file") FormDataContentDisposition content,
        @FormDataParam("path") String path)

这是我的web.xml文件中的servlet：

<servlet>
    <servlet-name>servlet_inspector</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>io.swagger.jaxrs.listing,com.sagasoftware.service;com.sagasoftware.custom.filter</param-value>
    </init-param>
    <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <param-value>
            org.glassfish.jersey.media.multipart.MultiPartFeature ,
            io.swagger.jaxrs.listing.ApiListingResource,
            io.swagger.jaxrs.listing.SwaggerSerializers,
    </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
