java - RestEasy代理框架文件上传

有谁知道如何使用ResteasyClient和代理框架发送请求并上传文件？

我知道用MultipartFormDataOutput发送请求的方法

ResteasyClient client = new ResteasyClientBuilder().build();

ResteasyWebTarget target = client.target("http://.../upload");

MultipartFormDataOutput mdo = new MultipartFormDataOutput();
mdo.addFormData("file", new FileInputStream(new File("/path/to/file.txt")),
    MediaType.APPLICATION_OCTET_STREAM_TYPE);
GenericEntity<MultipartFormDataOutput> entity = new GenericEntity<MultipartFormDataOutput>(mdo) {};

Response r = target.request().post( Entity.entity(entity, MediaType.MULTIPART_FORM_DATA_TYPE));

我想使用代理框架发送此请求，但它不起作用:(

FileUploadForm fileForm = new FileUploadForm();
//add file

ResteasyClient client = new ResteasyClientBuilder().build();
client.target(getHostUrl()).proxy(ProxyApi.class).uploadFile(fileForm);

@Path("/")
public interface ProxyApi {

    @POST
    @Produces(MediaType.MULTIPART_FORM_DATA)
    @Consumes(MediaType.APPLICATION_JSON)
    @Path("/upload")
    String uploadFile(@MultipartForm FileUploadForm form);
}


import org.jboss.resteasy.annotations.providers.multipart.PartType;
import javax.ws.rs.FormParam;

public class FileUploadForm {

    @FormParam("pos")
    @PartType("text/plain")
    public File image;

    //Get and set method

}

最佳答案

如果字段的类型是InputStream而不是File，则可以使用，例如：

FileUploadForm fileForm = new FileUploadForm();
fileForm.setImage(new FileInputStream("path/to/file"));

// ...

public class FileUploadForm {

    @FormParam("pos")
    @PartType("text/plain")
    public InputStream image;

    //Get and set method

}
