Question

我有以下Web服务，它应该通过HTML表单获取文件并将其保存在服务器上的某个位置。

@Path("/dv")
public class Uploader {

    @POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile(@FormDataParam("file") InputStream stream, @FormDataParam("file") FormDataContentDisposition fileDetails) {
        FileOperations fo = new FileOperations(stream); // My own class

        try {
            fo.saveToFile(fileDetails.getFileName());
        } catch (IOException ex) {
            ex.printStackTrace();
        }

        return Response.status(200).entity("").build();
    }
}

HTML表单是这样的。

<form name="upload-form" method="post" action="http://localhost:18080/dv/upload" enctype="multipart/form-data">
    <input type="file" name="file" id="file" />
    <input type="submit" />
</form>

每当我通过此表单上传文件时，都会收到错误

javax.ws.rs.NotSupportedException: Could not find message body reader for type: class com.sun.jersey.core.header.FormDataContentDisposition of content type: multipart/form-data;boundary=----WebKitFormBoundaryHvAymGjNVVEB1VWa

这是stacktrace

问题是我不明白这里有什么问题。我已将@Consumes（MediaType.MULTIPART_FORM_DATA）更改为@Consumes（“multipart / form-data”）但我得到了同样的错误。

浏览器使用以下Content-Type

发送HTTP数据包

Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryHvAymGjNVVEB1VWa

我从服务器得到415响应

415 Unsupported Media Type

如果有帮助，我使用的是谷歌浏览器。

peeskillet是正确的。我使用的是不正确的依赖项。我更新了我的pom.xml文件以包含RESTEasy jar并开始工作。

<dependency>
     <groupId>org.jboss.resteasy</groupId>
     <artifactId>resteasy-multipart-provider</artifactId>
</dependency>
