图像无法从数据库重新导入JFrame

Question

我想在数据库的JFrame中添加图像。但这不是重复的。我使用以下代码，这是从数据库中检索图像的正确方法吗？什么是解决方案???

 Blob blob = rs.getBlob("image");
             int blobLength = (int) blob.length();  

             byte[] bytes = blob.getBytes(1, blobLength);
            //blob.free();
             BufferedImage image = ImageIO.read(new ByteArrayInputStream(bytes));

             ImageIcon icon = new ImageIcon(bytes); // you can read straight from byte array
             l16 = new JLabel(icon);
             l16.setBounds(100, 100, 100, 50);
             add(l16);
