如何将字节数组转换为Blob

Question

我希望从数据库中获取一张图片。为此，我已经创建了一个图像的字节数组，并通过一个字符串传递，现在我想将该字符串转换为图像格式。我将该图像分配给一个Jlabel字段。 代码如下：

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
}
