com.ccniit.student.view.ImagePanel类
说明：此类是得到一个图片的路径然后把这个图片读取出来，显示在调用这个类的组件里面，这个类继承了JPanel，可以直接添加在窗口组件上面。这个类是用来读取学生照片，照片会根据窗口的大小来方法或缩小图片，但是图片不会失真 关键代码：
package com.ccniit.student.view;
import java.awt.Graphics;
import javax.swing.ImageIcon; import javax.swing.JPanel;
// 初始化图片的类
public class ImagePanel extends JPanel { private ImageIcon image; private int width; private int height;
private int imageWidth; private int imageHeight; private double rateImage; private double rateFrame;
ImagePanel(String path) {
image = new ImageIcon(path);
imageWidth = image.getIconWidth(); imageHeight = image.getIconHeight();
}
rateImage = (double) imageHeight / imageWidth; }
public ImageIcon getImageIcon() { return this.image; }
protected void paintComponent(Graphics g) { int frameWidth = this.getWidth(); int frameHeight = this.getHeight();
rateFrame = (double) frameHeight / frameWidth; if (rateFrame < rateImage) { height = frameHeight;
width = (int) (height / rateImage); } else {
width = frameWidth;
height = (int) (width * rateImage); }
// System.out.println(width + \
g.drawImage(image.getImage(), 0, 0, width, height, this); }
com.ccniit.student.view.ShowImage类
说明：这个类是显示放大过后的图片，当老师点击学生的图片的会new这个类的对象来，然后把这个图片重新显示在一个比较大的窗口里面，所以图片就会放大。
package com.ccniit.student.view;
import javax.swing.JDialog;
public class ShowImage extends JDialog { public ShowImage(ImagePanel image) { setSize(700, 700); setLocation(600, 0); add(image); } }
com.ccniit.student.view.Uploading类
说明：此类是上传照片的类，进入主界面的添加学生或修改学生成绩的时候就会new这个
