Dropwizard 0.8.1：多文件上传

Question

我正在使用dropwizard，我想一次上传多个文件。

如何更改我的代码以上传多个文件？

我正在使用org.glassfish.jersey.media', 'jersey-media-multipart', '2.17' 进行文件上传。

以下是我上传单个文件的代码：

@Path("/uploadPhoto")
@ApiOperation(
        value = "Upload a photo for an Ad",
        response = Response.class)
@POST
@Timed
@UnitOfWork
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public Response fileUploaded(@FormDataParam("file") final InputStream inputStream,
                         @FormDataParam("file") final FormDataContentDisposition contentDispositionHeader) {
    List<AdImage> images = new ArrayList<AdImage>();

        images.add(writeImageAndSave(inputStream
                , contentDispositionHeader));
    return Response.ok(toJson(images), MediaType.APPLICATION_JSON).build();

}

Answer 1

我发现这里是代码：

    @Path("/uploadPhoto")
@ApiOperation(
        value = "Upload a photo for an Ad",
        response = Response.class)
@POST
@Timed
@UnitOfWork
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public Response uploadFile(FormDataMultiPart multiPart) {


    List<AdImage> images = new ArrayList<AdImage>();
    List<FormDataBodyPart> bodyParts =
            multiPart.getFields("file");
    for (FormDataBodyPart part : bodyParts) {
        images.add(writeImageAndSave(part.getValueAs(InputStream.class
        ), part.getFormDataContentDisposition()));
    }

    return Response.ok(toJson(images), MediaType.APPLICATION_JSON).build();
}
