Jersey Multipart - 缺少起始边界

我有一个带有 Netty 的 jersy 2.13 服务器应用程序，我尝试上传带有“multipart/form-data”的文件，但出现此错误。

错误信息：

7605  10:01:49.309 [child-group-3-1] org.jvnet.mimepull.MIMEParsingException: Missing start boundary
66242 08:57:42.713 [child-group-3-1] ERROR ROOT       - No codec available to display error for 'Content-Type:multipart/form-data; boundary=----webkitformboundaryv4kegleyi4tkjp8j'

我的依赖

compile group: "org.glassfish.jersey.core",             name: "jersey-server",                  version: "2.13"
compile group: "org.glassfish.jersey.media",            name: "jersey-media-json-jackson",      version: "2.13"
compile group: "org.glassfish.jersey.media",            name: "jersey-media-multipart",         version: "2.13"

我的资源：

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public void uploadFile(@FormDataParam("file") InputStream stream, @FormDataParam("file")    FormDataContentDisposition contentDispositionHeader)
{
    System.out.println("Enter uploadFile");

    String outputPath = "C:/upload/";
    java.nio.file.Path outPath = FileSystems.getDefault().getPath(outputPath, contentDispositionHeader.getFileName());
    try
    {
        Files.copy(stream, outPath);
    }
    catch (IOException e)
    {
        throw Throwables.propagate(e);
    }
}

我的应用程序：

public JerseyApplication()
{
    super(JacksonMapper.class, JacksonFeature.class);

    register(new InjectionBinder());
    register(new MultiPartFeature());
    register(new MyFileUploader());
}

我的客户测试

<form action="http://localhost/api/upload" method="post" enctype="multipart/form-data">
<p><input id="uploadInput" type="file" name="file"></p>
<p><input type="submit" formenctype="multipart/form-data" value="Send file"></p>
</form>

如果我用球衣1.8（compile group: "com.sun.jersey.contribs", name: "jersey-multipart", version: "1.18.3"），如果我删除它就可以工作FormDataContentDisposition从函数uploadFile。如果我不删除它，我在启动时会出现此错误：

如果我删除FormDataContentDisposition来自uploadFile函数我的文件内容如下：

------WebKitFormBoundaryATOqpm55xXBvTACH
Content-Disposition: form-data; name="file"; filename="mytxt.txt"
Content-Type: text/plain

my file content
------WebKitFormBoundaryATOqpm55xXBvTACH--

我在 Jersey 中遇到了类似的问题，使用 Chrome 时分段文件上传会失败，但使用 Firefox 时会成功。

正如 plemay 提到的，问题在于 Chrome 在 Content-Type 标头中发送包含大写和小写字母的边界，但服务器端的某些操作将其全部转换为小写，导致正文解析失败，并显示“ MIMEParsingException：缺少开始边界。”

在我的例子中，原因是 Jersey 使用 SPI 在运行时加载类，并且它从 Apache CXF 中获取了一个有缺陷的 MediaType 实现，该实现将标头值转换为小写。修复方法是升级/摆脱 CXF，或强制 Jersey 使用不同的 MediaType 实现。
