Java GUI实现学生成绩管理系统
学习java有一年多了，一直在做web方面的练习，在一个项目中发现需要用到GUI的相关知识，结果没法做出来，网上这方面的文章又不是很多，所有只好自己硬着头皮从头再学一遍了，不过学习后发现，其实GUI是非常有趣的，他并不像WEB程序一样依赖互联网，而且还有许多布局和android相差不是很大，这才发现自己竟又爱上GUI的开发了，不多说了，直接上代码吧，相信有过android或相关界面开发的都明白这其中的道理。
先看看效果吧
1.登录主界面
package edu.gzu.stuManager;
import java.awt.EventQueue;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import java.awt.Toolkit;
import javax.swing.JTextField;
import edu.gzu.stuManager.Dao.UserLoginValid;
import edu.gzu.stuManager.Domain.StudentInfo;
import edu.gzu.stuManager.View.StudentMainView;
import java.awt.Choice;
import java.awt.Font;
import java.awt.Button;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
public class MainUI {
private JFrame frame;
private JTextField textField;
private JTextField textField_1;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
MainUI window = new MainUI();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public MainUI() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setTitle("\u6210\u7EE9\u7BA1\u7406\u7CFB\u7EDF\uFF08\u767B\u5F55\uFF09");
frame.setIconImage(Toolkit.getDefaultToolkit().getImage(MainUI.class.getResource("/image/func_list7_privmana.png")));
frame.setBounds(400, 250, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
JLabel lblNewLabel = new JLabel("\u5B66\u751F\u6210\u7EE9\u7BA1\u7406\u7CFB\u7EDF\u7528\u6237\u767B\u5F55\uFF01");
lblNewLabel.setFont(new Font("宋体", Font.PLAIN, 16));
lblNewLabel.setBounds(111, 17, 287, 15);
frame.getContentPane().add(lblNewLabel);
JLabel lblNewLabel_1 = new JLabel("\u7528\u6237\u540D\uFF1A");
lblNewLabel_1.setFont(new Font("宋体", Font.PLAIN, 14));
lblNewLabel_1.setBounds(87, 67, 67, 15);
frame.getContentPane().add(lblNewLabel_1);
textField = new JTextField();
textField.setBounds(154, 64, 141, 21);
frame.getContentPane().add(textField);
textField.setColumns(10);
JLabel label = new JLabel("\u5BC6 \u7801\uFF1A");
label.setFont(new Font("宋体", Font.PLAIN, 14));
label.setBounds(87, 108, 67, 15);
frame.getContentPane().add(label);
textField_1 = new JTextField();
textField_1.setColumns(10);
textField_1.setBounds(154, 103, 141, 21);
frame.getContentPane().add(textField_1);
JLabel lblNewLabel_2 = new JLabel("\u6211\u7684\u8EAB\u4EFD\u662F\uFF1A");
lblNewLabel_2.setFont(new Font("宋体", Font.PLAIN, 14));
lblNewLabel_2.setBounds(105, 150, 97, 15);
frame.getContentPane().add(lblNewLabel_2);
final Choice choice = new Choice();
choice.setBounds(210, 147, 74, 21);
choice.add("学生");
choice.add("教师");
choice.add("系统管理员");
frame.getContentPane().add(choice);
Button button = new Button("\u767B\u5F55");
button.setBounds(87, 194, 76, 23);
button.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
String user=textField.getText();
String password=textField_1.getText();
String shenfen=choice.getSelectedItem();
if(user.equals("")||user==null){
JOptionPane.showMessageDialog(frame, shenfen+":您好，帐号不能为空！");
return;
}else if(password.equals("")||password==null){
JOptionPane.showMessageDialog(frame, shenfen+":您好，密码不能为空！");
return;
}else{
StudentInfo stu=new StudentInfo(Integer.parseInt(user),
Integer.parseInt(password),shenfen);
UserLoginValid dao=new UserLoginValid();
String result=dao.isValid(stu);
if("登录成功！".equals(result)){
JOptionPane.showMessageDialog(frame,result);
StudentMainView index=new StudentMainView(stu);
JFrame frame2=index.getFrame();
frame2.setVisible(true);
frame.dispose();
}else{
JOptionPane.showMessageDialog(frame,result);
}
}
}
});
frame.getContentPane().add(button);
Button button_1 = new Button("\u53D6\u6D88");
button_1.setBounds(219, 194, 76, 23);
frame.getContentPane().add(button_1);
}
}
2.登录验证逻辑
package edu.gzu.stuManager.Dao;
import edu.gzu.stuManager.Domain.StudentInfo;
public class UserLoginValid {
public String isValid(StudentInfo stu){
int idnum=stu.getIdnum();
int password=stu.getPassword();
String idntify=stu.getIdentify();
String result=null;
if("学生".equals(idntify)){
if(idnum==1207010209&&password==123){
stu.setName("刘明胜 同学");
result="登录成功！";
}else{
result="学生帐号中不存在此用户，请确认身份后再次登录！";
}
}else if("教师".equals(idntify)){
if(idnum==1174386356&&password==123){
stu.setName("刘明胜 老师");
result="登录成功！";
}else{
result="教师帐号中不存在此用户，请确认身份后再次登录！";
}
}else if("系统管理员".equals(idntify)){
if(idnum==999999&&password==123){
stu.setName("系统管理员");
result="登录成功！";
}else{
result="系统管理员帐号中不存在此用户，请确认身份后再次登录！";
}
}
return result;
}
}
3.用户对象（这是一个简单bean）
package edu.gzu.stuManager.Domain;
public class StudentInfo {
private int idnum;
private String name;
private int password;
private String identify;
public StudentInfo(int idnum,int password, String identify) {
super();
this.idnum = idnum;
this.password = password;
this.identify = identify;
}
public int getIdnum() {
return idnum;
}
public void setIdnum(int idnum) {
this.idnum = idnum;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getPassword() {
return password;
}
public void setPassword(int password) {
this.password = password;
}
public String getIdentify() {
return identify;
}
public void setIdentify(String identify) {
this.identify = identify;
}
}
4.登录成功后的主界面
package edu.gzu.stuManager.View;
import java.awt.Button;

choice.add("选择课程");
choice.add("高等数学");

choice.add("毛泽东思想");
choice.add("计算机图形学");
choice.addItemListener(new ItemListener() {
@Override
public void itemStateChanged(ItemEvent e) {
Object[] objs=e.getItemSelectable().getSelectedObjects();
for(Object ob:objs){
// JOptionPane.showMessageDialog(frame, ob.toString());
if("高等数学".equals(ob.toString())){
textField_2.setText("高等数学");
textField_3.setText("98");
}else if("大学英语".equals(ob.toString())){
textField_2.setText("大学英语");
textField_3.setText("87");
}else if("马列主义".equals(ob.toString())){
textField_2.setText("马列主义");
textField_3.setText("88");
}else if("毛泽东思想".equals(ob.toString())){
textField_2.setText("毛泽东思想");
textField_3.setText("73");
}else if("计算机图形学".equals(ob.toString())){
textField_2.setText("计算机图形学");
textField_3.setText("97");
}
}
}
});
panel_1.add(choice);
}
}
这样就能轻松实现登录验证了，本打算从数据库读取数据的，由于时间关系，这里就简单的直接验证了，后续有时间的话再做其他的部分。
