如何將字節數組轉換爲blob

Question

我想從數據庫中獲取圖像。爲此，我爲圖像創建了一個字節數組，該數組由字符串傳遞，現在我想將該字符串轉換爲圖像格式。我將該圖像分配給Jlabel字段。代碼如下：

try 
{ 
    Blob image_vis = rs1.getBlob(10); 
    InputStream x=image_vis.getBinaryStream(); 
    OutputStream out=new FileOutputStream(string_op); 
    byte[] bytes = string_op.getBytes(); 
    String s=new String(bytes); 
    System.out.println(+s); //prints bytes for the string 
    ImageIcon icon_cap = new ImageIcon(string_op); 
    image_cap.setIcon(icon_cap); //prints nothing to Jlabel 
    //image_cap.setText(s);  //prints a path of a image 
    }

Blob blob = new javax.sql.rowset.serial.SerialBlob(bytes);
