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; 
 
  
 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(); 
 } 
 } 
 }); 
 } 
 
  
 public MainUI() { 
 initialize(); 
 } 
 
  
 private void initialize() { 
 frame = new Jframe(); 
 frame.setTitle("u6210u7EE9u7BA1u7406u7CFBu7EDFuFF08u767Bu5F55uFF09"); 
 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("u5B66u751Fu6210u7EE9u7BA1u7406u7CFBu7EDFu7528u6237u767Bu5F55uFF01"); 
 lblNewLabel.setFont(new Font("宋体", Font.PLAIN, 16)); 
 lblNewLabel.setBounds(111, 17, 287, 15); 
 frame.getContentPane().add(lblNewLabel); 
 
 JLabel lblNewLabel_1 = new JLabel("u7528u6237u540DuFF1A"); 
 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 u7801uFF1A"); 
 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("u6211u7684u8EABu4EFDu662FuFF1A"); 
 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("u767Bu5F55"); 
 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("u53D6u6D88"); 
 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; 
import java.awt.Canvas; 
import java.awt.Choice; 
import java.awt.Color; 
import java.awt.Toolkit;

 private StudentInfo info; 
 
  
 public StudentMainView(StudentInfo info) { 
 this.info=info; 
 } 
 
 public Jframe getframe(){ 
 initialize(); 
 return frame; 
 } 
 
  
 public void initialize() { 
 frame = new Jframe(); 
 frame.setTitle("u6210u7EE9u7BA1u7406u7CFBu7EDFuFF08u5B66u751Fu7248uFF09");

 textField_1.setText(info.getName()); 
 panel.add(textField_1); 
 textField_1.setColumns(10); 
 
 Canvas canvas = new Canvas(); 
 canvas.setBackground(Color.BLUE); 
 canvas.setBounds(22, 100, 205, 1); 
 panel.add(canvas);

 lblNewLabel_5.setBounds(160, 116, 43, 15); 
 panel.add(lblNewLabel_5); 
 
 textField_2 = new JTextField(); 
 textField_2.setBounds(22, 140, 123, 21); 
 panel.add(textField_2); 
 textField_2.setColumns(10); 
 
 textField_3 = new JTextField(); 
 textField_3.setBounds(159, 140, 66, 21); 
 panel.add(textField_3); 
 textField_3.setColumns(10); 
 
 JPanel panel_1 = new JPanel(); 
 panel_1.setBounds(317, 52, 110, 180); 
 frame.getContentPane().add(panel_1); 
 panel_1.setLayout(null); 
 
 JLabel lblNewLabel_6 = new JLabel("u64CDu4F5Cu83DCu5355"); 
 lblNewLabel_6.setBounds(15, 10, 54, 15); 
 panel_1.add(lblNewLabel_6); 
 
 Button button = new Button("u7B2Cu4E00u95E8u8BFEu7A0B"); 
 button.setBounds(10, 31, 76, 23); 
 panel_1.add(button); 
 
 Button button_1 = new Button("u4E0Bu4E00u95E8u8BFEu7A0B"); 
 button_1.setBounds(10, 61, 76, 23); 
 panel_1.add(button_1); 
 
 Button button_2 = new Button("u4E0Au4E00u95E8u8BFEu7A0B"); 
 button_2.setActionCommand("u4E0Au4E00u95E8u8BFEu7A0B");

 button_3.setBounds(10, 117, 76, 23); 
 panel_1.add(button_3); 
 
 Choice choice = new Choice(); 
 choice.setBounds(10, 149, 76, 21); 
 choice.add("选择课程"); 
 choice.add("高等数学"); 
 choice.add("大学英语"); 
 choice.add("马列主义"); 
 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。
