java byte数组转image,在Java中将字节数组转换为image（blob）

The code for the image conversion from byte array to image i.e blob.

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

}

I am able to get path of an image, but I am anable to convert it into image format, so that it will display on a form. please help me.

Try This..

try

{

Blob image_vis = rs1.getBlob("blobColumn");

int blobLength = (int) image_vis.length();

byte[] bytes = image_vis.getBytes(1, blobLength);

image_vis.free();

final BufferedImage bufferedImage = ImageIO.read(new ByteArrayInputStream(bytes));

ImageIO.write(bufferedImage, "jpg", new File("ImagePath/ImageName.jpg"));

}

Later you can pick up the image..
