public class ImgTest {

public Connection getConnection() {

}

public static void main(String[] args) {
ImgTest it = new ImgTest();
it.getConnection();
it.getDate();
}

private Connection con = null;
private Statement s = null;
private String str = null;

}
这个是把图片写进数据库的代码;

public class outImage {
public void getImage() {
ImgTest it = new ImgTest();
try {
Statement s = it.getConnection().createStatement();
ResultSet rs = s.executeQuery("select * from ImageTest");
while (rs.next()) {
buffer = rs.getBytes(1);
}
DataOutputStream out = new DataOutputStream(new
BufferedOutputStream(new FileOutputStream("2.jpg")));
out.write(buffer);
} catch (SQLException se) {
se.printStackTrace();
} catch (IOException ie) {
ie.printStackTrace();
}
}

public static void main(String[] args)
{
outImage oi = new outImage();
oi.getImage();
}

private byte[] buffer;

}
这个是把图片从数据库中读出来的代码!读图片的操作读出来的图片什么都没有!谁能帮我改一下啊!
