如何将字节数组转换为blob

Question

我想从数据库中获取图像。为此，我为图像创建了一个字节数组，该数组由字符串传递，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 
    }

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