Question

我有一个带有Netty的jersy 2.13的服务器应用程序，我尝试使用＆＃34; multipart / form-data＆＃34;上传文件。我收到了这个错误。

错误讯息：

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);
    }
}

我的申请：

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

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

我的客户端测试

<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"），那么如果我从函数FormDataContentDisposition中移除uploadFile，它就会正常工作。如果我不删除它，我在启动时会出现此错误：

如果我从FormDataContentDisposition功能中移除uploadFile，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--

Answer 1

我遇到类似的问题，在使用Chrome时，多部分文件上传失败，但使用Firefox取得了成功。

正如所提到的那样，问题是Chrome在Content-Type标头中发送包含大写和小写字母的边界，但服务器端的某些内容将其全部转换为小写，导致正文解析为＆＃34; MIMEParsingException失败：缺少起始边界。＆＃34;

我的案例中的原因是Jersey使用SPI在运行时加载类，并且它从Apache CXF中获取了一个错误的MediaType实现，它将头值转换为小写。解决方法是升级/删除CXF，或强制Jersey使用不同的MediaType实现。

有关详细信息，请参阅JERSEY-1377。

Answer 2

问题在于从浏览器收到的边界。

Chrome界限：boundary=----webkitformboundary2fvqbgcbynvtvptx（无效）

Firefox边界：boundary=---------------------------13335242989826（工作）

Answer 3

我花了大约8个小时来调试....然后我发现了一个简单的事实：

边界应该在内容类型中定义，如下所示：

android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

我希望有人能告诉我这个以节省时间......所以希望它对那些像我一样迷失的人有所帮助。

我发现了另一篇帖子解决了这个问题：What is the boundary in multipart/form-data?

Answer 4

org.jvnet.mimepull.MIMEParsingException：缺少开始边界：

即使我们拥有适当的Content-Type：multipart / form-data; boundary = ---- webkitformboundary2fvqbgcbynvtvptx出现异常。

解决方案是：检查Web过滤器是否还具有其他任何spring multiform-data过滤器。通过评论春季多部分过滤器进行测试，然后尝试进行平针织剩余上传，然后流量将按预期工作。

注意：请确保，如果您同时需要两个过滤器，请更改url-pattern以控制同一应用程序中的URL。

我的情况是：我评论了org.springframework.web.multipart.support.MultipartFilter，然后按预期工作正常。
