Java GUI实现学生成绩管理系统

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

}

}

}

});

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。
