使用富文件上傳進行上傳時出錯

我在Java Web項目上工作。我有一個豐富的xthml頁面：fileUpload。在監聽我得到如下輸入流：使用富文件上傳進行上傳時出錯

public void uploadListener(FileUploadEvent event) { 

     try { 
      in = event.getUploadedFile().getInputStream(); 
      fileName = event.getUploadedFile().getName(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } finally { 
      IOUtils.closeQuietly(in); 
     } 
    }

，然後按鈕保存我試圖通過下面的代碼文件到硬盤上載：

public void uploadFile(){ 
     try { 
     String path=some_path + currentReport.getFilename(); 
     File targetFile = new File(path); 

     java.nio.file.Files.copy(
       in, 
      targetFile.toPath(), 
      StandardCopyOption.REPLACE_EXISTING); 

     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     }  
}

我收到以下錯誤：

有什麼建議嗎？感謝和提前問候。

好了，所以我自己解決的問題。我關閉了doUpload函數中的inputStream，如下所示：

public void uploadListener(FileUploadEvent event) { 

     try { 
      in = event.getUploadedFile().getInputStream(); 
      fileName = event.getUploadedFile().getName(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 

public void uploadFile(){ 
     try { 
     String path=some_path + currentReport.getFilename(); 
     File targetFile = new File(path); 

     java.nio.file.Files.copy(
       in, 
      targetFile.toPath(), 
      StandardCopyOption.REPLACE_EXISTING); 

     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } finally { 
      IOUtils.closeQuietly(in); 
     } 
}

附加檢查，如果你的InputStream已關閉，然後調用reset

試試這個：

public void uploadFile(){ 
     try { 
     String path=some_path + currentReport.getFilename(); 
     File targetFile = new File(path); 

     java.nio.file.Files.copy(
       in, 
      targetFile.toPath(), 
      StandardCopyOption.REPLACE_EXISTING); 

     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
      in.reset(); 
      java.nio.file.Files.copy(
       in, 
      targetFile.toPath(), 
      StandardCopyOption.REPLACE_EXISTING); 
     }  
}

感謝@ Abihabi87的回覆。你能寫一些例子嗎？ –

現在我有其他消息： SEVERE：java.io.IOException：標記/重置不支持 –

我解決了這個問題。感謝阿比海btw。 –
