jax-rs - 使用 JAX-RS 上传文件会给出错误的参数传递错误

Question

我想用 jax-rs 上传文件。我启动tomcat，然后从邮递员发送请求，但是，我得到了下面的异常。我尝试更改 resteasy 依赖项，但没有解决我的问题。

 Failed executing POST files/upload
    org.jboss.resteasy.spi.InternalServerErrorException: Bad arguments passed to public javax.ws.rs.core.Response

以下是我的上传课程。

@Path("/files")
public class FileUpload {
    @POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile(
            @FormDataParam("file") InputStream uploadedInputStream,
            @FormDataParam("file") FormDataContentDisposition fileDetail) {
        String fileLocation = "/home/" + fileDetail.getFileName();
        //saving file
        try {
            FileOutputStream out = new FileOutputStream(new File(fileLocation));
            int read = 0;
            byte[] bytes = new byte[1024];
            out = new FileOutputStream(new File(fileLocation));
            while ((read = uploadedInputStream.read(bytes)) != -1) {
                out.write(bytes, 0, read);
            }
            out.flush();
            out.close();
        } catch (IOException e) {e.printStackTrace();}
        String output = "File successfully uploaded to : " + fileLocation;
        return Response.status(200).entity(output).build();
    }
}

pom.xml 文件如下。我很困惑这是关于依赖关系的问题。
