我在stackoverflow上看到了多个答案,但无法识别我的pom.xml有什么问题。 我必须在服务器上上传文件,所以我使用的是this link的FormDataMultiPart修改后的代码
我的代码为:
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import org.glassfish.jersey.media.multipart.ContentDisposition;
import org.glassfish.jersey.media.multipart.FormDataBodyPart;
import org.glassfish.jersey.media.multipart.FormDataMultiPart;
@Path("/files")
public class JerseyFileUpload {
private static final String SERVER_UPLOAD_LOCATION_FOLDER = "E:/Upload_Files/";
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(FormDataMultiPart form) {
FormDataBodyPart filePart = form.getField("file");
ContentDisposition headerOfFilePart = filePart.getContentDisposition();
InputStream fileInputStream = filePart.getValueAs(InputStream.class);
String filePath = SERVER_UPLOAD_LOCATION_FOLDER + headerOfFilePart.getFileName();
// save the file to the server
saveFile(fileInputStream, filePath);
String output = "File saved to server location using FormDataMultiPart : " + filePath;
return Response.status(200).entity(output).build();
}
// save uploaded file to a defined location on the server
private void saveFile(InputStream uploadedInputStream, String serverLocation) {
try {
OutputStream outpuStream = new FileOutputStream(new File(
serverLocation));
int read = 0;
byte[] bytes = new byte[1024];
outpuStream = new FileOutputStream(new File(serverLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
outpuStream.write(bytes, 0, read);
}
outpuStream.flush();
outpuStream.close();
uploadedInputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
我的pom.xlm是

我正在使用Jersey版本2.16,即使我使用的是jersey-media-multipart版本2.25,我仍然会得到&#34;不支持的媒体类型&#34;由于版本有问题吗?或者这个pom.xml有什么问题?
谢谢,非常感谢任何帮助。
答案 0 :(得分:1)
您仍然需要注册MultiPartFeature
附带的jersey-media-multipart
。该功能将注册处理多部分请求所需的提供程序。您当前看到的错误是因为没有注册的提供商可以处理FormDataMultiPart
。有关注册的几种不同方式,请参阅this post
