IllegalStateException：getOutputStream（）已經被調用這個響應檢索圖像

我想要顯示特定文件夾中的圖像。當我從服務器發送請求，在客戶端上我得到以下異常「**的getOutputStream（）已經被調用，這種響應」IllegalStateException：getOutputStream（）已經被調用這個響應檢索圖像

這是HTML代碼

<td><img id="imagePreview" src="../catalogue/displayCatalogueImage.action?catalogueTitleNumber=${imageDisplay}" alt="Item Image" width="96" height="80"/></td>

聽到「catalogueTitleNumber」是獨一無二的圖像的名稱

這是我的控制器

@RequestMapping("/catalogue/displayCatalogueImage.action") 
    public String getDisplayImage(String catalogueTitleNumber, HttpServletRequest request) { 

     try { 

      System.out.println("Image Display Title number = > "+catalogueTitleNumber); 

      if(catalogueTitleNumber!= null && !"".equals(catalogueTitleNumber)){ 

       File image = new File("images/"+catalogueTitleNumber); 

       BufferedImage originalImage=ImageIO.read(image); 

       ByteArrayOutputStream baos=new ByteArrayOutputStream(); 

       ImageIO.write(originalImage, "jpg", baos); 

       byte[] imageInByte = baos.toByteArray(); 

       request.setAttribute("imageInByte", imageInByte); 

       baos.close(); 

      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

     return "catalogue/displayCatalogueImage"; 
    }

這是「displayCatalogueImage.JSP」頁面，幫助寫的圖像要求img標籤

<%@page import="java.io.OutputStream"%> 
<%@page import="java.sql.Blob"%> 
<% 

    try{ 

     byte[] image = (byte[]) request.getAttribute("imageInByte"); 

     response.setContentType("image/png"); 
     OutputStream os = response.getOutputStream(); 
     os.write(image); 

     os.flush(); 
     os.close(); 
     out.clear(); 

     out=pageContext.pushBody(); 

    } catch(Exception ex) { 

     out.println("Unable To Display image"); 
     out.println("Image Display Error = " + ex.getMessage()); 

    } 

%>

在開始（僅一次）它顯示圖像的話我是不斷收到此異常

後聽到你可以說我打電話'的通知.write'兩次在控制器中，另一個在jsp頁面中（在jsp中.write幫助寫入字節碼，並在控制器中幫助獲取圖像的字節碼）我試圖避免在控制器中寫入'.write'它沒有給出任何錯誤，但沒有用... ...！

即

private byte[] image_byte_data(BufferedImage image) 
{ 
    WritableRaster raster = image.getRaster(); 
    DataBufferByte buffer = (DataBufferByte)raster.getDataBuffer(); 
    return buffer.getData(); 
}

我被控制器調用上述方法試圖和初始化爲byte []連字節變量得到的圖像，但jsp頁面代碼的字節碼沒有寫......？

任何幫助將不勝感激，謝謝。

你可以添加stacktrace嗎？ – Fildor

請認真檢查一下我添加了堆棧跟蹤... –

如果您只是試圖發回圖像數據以響應客戶端圖像請求，請勿使用JSP。它沒有任何意義，因爲你沒有返回任何標記。只需將圖像數據直接寫入控制器的輸出流即可。這裏有一個例子，重構一點：

@RequestMapping("/catalogue/displayCatalogueImage.action") 
public ResponseEntity getDisplayImage(String catalogueTitleNumber, HttpServletResponse response) throws Exception { 

    System.out.println("Image Display Title number = > "+catalogueTitleNumber); 

    if (StringUtils.isNotEmpty(catalogueTitleNumber)) { 

     response.setHeader("Content-Type", "image/png"); 
     FileInputStream fin = new FileInputStream("images/"+catalogueTitleNumber); 
     ServletOutputStream out = response.getOutputStream(); 

     IOUtils.copy(fin, out); 
     IOUtils.closeQuietly(fin); 

     response.flushBuffer(); 

     return new ResponseEntity(HttpStatus.OK); 
    } 

    return new ResponseEntity(HttpStatus.NOT_FOUND); 
}

感謝您的寶貴答案它工作正常... –

你是第一個與周圍的Writerout幾行後檢索OutputStream和然後仍然混亂。你不能同時兼任。只需刪除out調用和事情應該沒事，

我按照您的說法移除了，但仍然出現相同的錯誤... –

兩個調用都被刪除了嗎？即clear（）和pushBody（）？ – hendrik

雅我刪除了兩個電話 –

IllegalStateException：getOutputStream（）已經被調用這個響應檢索圖像
