Jersey API中不支持的媒體類型錯誤

我在stackoverflow上看到了多個答案，但卻無法確定我的pom.xml有什麼問題。我上傳的服務器上的文件，所以我使用的是修改後的代碼從FormDataMultiPart的this link Jersey API中不支持的媒體類型錯誤

我的代碼爲：

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pom.xlm是

我正在使用Jersey版本2.16，即使我使用的是澤西媒體多媒體類型，我仍然會得到「不支持的媒體類型」 rsion 2.25。有版本問題嗎？或者這個pom.xml有什麼問題？

謝謝，將不勝感激任何幫助。

你可以在你的'uploadFile'方法參數中使用'@FormDataParam（「file」）InputStream fileInputStream'，並檢查。 –

怎麼樣？不要讓它..而不是FormDataBodyPart我應該使用FormDataParam？ – Pepper

它沒有工作，我得到錯誤500，「org.glassfish.jersey.server.model.ModelValidationException：應用程序資源模型的驗證在應用程序初始化過程中失敗。」 – Pepper

您還需要註冊jersey-media-multipart附帶的MultiPartFeature。該功能將註冊處理多部分請求所需的提供程序。您目前看到的錯誤是因爲沒有註冊的供應商可以處理FormDataMultiPart。見this post有幾種不同的註冊方法
