Java 将文件发布到resteasy

我在这篇文章的底部看到了错误。有人能发现这个问题吗

Resteasy HTTP调用：

@POST
@Path("/")
public void upload(final @MultipartForm FileUploadForm form) {
    LOG.info(String.format("/%s/%s/%s/%s", form.getA(), form.getB(), form.getC(), form.getD()));
}

关联的Java模型：

private class FileUploadForm {
    private String a;
    private String b;
    private String c;
    private String d;

    private byte[] file;

    @FormParam("a") @PartType(MediaType.TEXT_PLAIN)
    public void setA(final String a) { this.a = a; }
    public String getA() { return a; }

    @FormParam("b") @PartType(MediaType.TEXT_PLAIN)
    public void setB(final String b) { this.b = b; }
    public String getB() { return b; }

    @FormParam("c") @PartType(MediaType.TEXT_PLAIN)
    public void setC(final String c) { this.c = c; }
    public String getC() { return c; }

    @FormParam("d") @PartType(MediaType.TEXT_PLAIN)
    public void setD(final String d) { this.d = d; }
    public String getD() { return d; }

    @FormParam("file") @PartType(MediaType.APPLICATION_OCTET_STREAM)
    public void setFile(final byte[] file) { this.file = file; }
    public byte[] getFile() { return file; }
}

JQuery调用代码：

$('div#upload form').submit(function() {
    $.ajax({
        'url': '/api/',
        'type': 'POST',
        'data': new FormData($('div#upload form')[0]),
        'contentType': false,
        'cache': false,
        'processData': false
    });

    return false;
});

调用curl也会得到相同的结果：

    curl -F file=testimage.jpg http://hostname/api/

错误：

啊。我似乎已经弄明白了。FileUploadForm是带有upload方法的Resteasy类中的一个内部类

将其拆分为自己的类使其工作。疯了
