MySQL Blob到Netbeans JLabel

我得到的文件名应该是这样的

  txtPicPath.setText(file.getAbsoluteFile().toString());

而且我使用了这些代码，而且也适合jlabel的大小

 ResultSet rst = MyDB.rsFetch("SELECt `Picture` FROM `photo` WHERe `Employee ID` = '"+ Data.User.getText()+"'");         while (rst.next()) {         Blob filenameBlob = rst.getBlob("Picture");         byte[] content = filenameBlob.getBytes(1L,(int)filenameBlob.length());         ImageIcon ik = new ImageIcon(content);         Image img = ik.getImage();         Image newimg = img.getScaledInstance(Data.picture.getWidth(), Data.picture.getHeight(), java.awt.Image.SCALE_SMOOTH);         ik = new ImageIcon(newimg);         Data.picture.setIcon(ik);         }
