在我们的应用程序中，我们希望通过android使用rest api上传文件和有关文件的信息。这是我的pom。xml

import javax.ws.rs.core.MediaType;

@Path("/notes")
public class Notes{
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public String fileUpload(@FormDataParam("file")InputStream uploadedInputStream,
        @FormDataParam("file")FormDataContentDisposition fileDetial)
{

    String uploadedFileLocation="D:\\megabizz"+fileDetial.getFileName();
    writeToFile(uploadedInputStream, uploadedFileLocation);
    return"file successfully uploaded";
}
private void writeToFile(InputStream uploadedInputStream,String uploadedFileLocation) {

        try {
            OutputStream out = new FileOutputStream(new File(
                    uploadedFileLocation));
            int read = 0;
            byte[] bytes = new byte[1024];

            out = new FileOutputStream(new File(uploadedFileLocation));
            while ((read = uploadedInputStream.read(bytes)) != -1) {
                out.write(bytes, 0, read);
            }
            out.flush();
            out.close();
        } catch (IOException e) {

            e.printStackTrace();
        }

    }
}

我没有弄错什么，在添加最后3个依赖项后，我无法访问我项目的任何资源。即使我没有上传文件并尝试访问其他资源，那么我也会收到这个错误。请帮我解决这个问题。

不要混用球衣的主要版本。它们不兼容，即

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-server</artifactId>
    <version>1.8</version>
</dependency>

<dependency>
    <groupId>com.sun.jersey.contribs</groupId>
    <artifactId>jersey-multipart</artifactId>
    <version>1.8</version>
</dependency>

把那两个人干掉。对于多部分支持，请使用

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>2.16</version>
</dependency>

这是泽西2. x支持。然后您需要注册MultiPartFeature。这取决于您如何配置您的应用程序，以及如何做到这一点。这些链接可能会有所帮助：链接、链接、链接
