Jersey Multipart - 缺少起始边界

Question

我有一个带有 Netty 的 jersy 2.13 的服务器应用程序，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>

如果我使用了 Jersey 1.8 ( compile group: "com.sun.jersey.contribs", name: "jersey-multipart", version: "1.18.3" )，如果我删除了 FormDataContentDisposition 就可以了来自函数 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，其中使用 Chrome 时分段文件上传会失败，但使用 Firefox 会成功。

正如 plemay 所提到的，问题是 Chrome 在 Content-Type header 中发送了一个包含大写和小写字母的边界，但服务器端的某些内容正在将其全部转换为小写，导致正文解析失败，并显示“MIMEParsingException:缺少起始边界。”

在我的案例中，原因是 Jersey 在运行时使用 SPI 加载类，并且它从 Apache CXF 中获取了一个有问题的 MediaType 实现，该实现将 header 值转换为小写。解决方法是升级/摆脱 CXF，或强制 Jersey 使用不同的 MediaType 实现。

见 JERSEY-1377更多细节。
