项目名称：学生信息管理系统

样品展示：

学生管理系统

系统简介（思维）：

该项目用于学习巩固java知识，包含很多知识应用，（注意：本篇文章项目不含数据库内容，采取IO流代替写进文本，保存数据），与君共同成长学习，源代码加微：wxzhangguangpeng

技术需求：

java基础知识面向对象IO流异常处理Swing程序设计

实现步骤（并不规范，个人思路）：

第一步：注册界面

新建类：Register，继承JFrame类窗体基础调整新建标签将标签加入到窗体容器中如下

package StudentManagementSystem12;

import javax.swing.*;

import java.awt.*;

public class Register extends JFrame{

public Register() {

setTitle("StudentManagementSystem");

setBounds(600, 200, 350, 300);//窗体标题

setDefaultCloseOperation(EXIT_ON_CLOSE);//关闭方式的设置

Container c1 = getContentPane();//将窗体变为容器

JPanel jPanel1 = new JPanel(new BorderLayout()); // 使用 BorderLayout布局管理器

JLabel jLabel1 = new JLabel("Register");//用标签写出标题

Font font = new Font("Arial", Font.PLAIN, 40);//调整字体大小和样式

jLabel1.setFont(font);

jLabel1.setForeground(Color.BLACK);

jLabel1.setHorizontalAlignment(SwingConstants.CENTER);//标题位置

jPanel1.add(jLabel1, BorderLayout.NORTH); // 将 JLabel 添加到北部

c1.add(jPanel1);

setVisible(true);//显示窗体

}

public static void main(String[] args) {

new Register();

}

添加用户名和密码的文本框和文字标签，用SpringLayout布局管理器来规划位置添加三个按钮，也用SpringLayout布局管理器来规划位置根据事件监听器的知识进行按钮的制定HomePage可以不设置监听器完整的注册注册代码文件如下（账号文件位置需要自己修改）

package StudentManagementSystem;

import javax.swing.*;

import java.awt.*;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.io.*;

import java.util.HashMap;

import java.util.Map;

public class Register extends JFrame {

public JTextField textField1;

public JPasswordField textField2;

public JPasswordField textField3;

public Register() {

setTitle("StudentManagementSystem");

setBounds(600, 200, 350, 300);

setDefaultCloseOperation(EXIT_ON_CLOSE);

Container c1 = getContentPane();

JPanel jPanel1 = new JPanel(new BorderLayout()); // 使用 BorderLayout

JLabel jLabel1 = new JLabel("Register");

Font font = new Font("Arial", Font.PLAIN, 40);

jLabel1.setFont(font);

jLabel1.setForeground(Color.BLACK);

jLabel1.setHorizontalAlignment(SwingConstants.CENTER);

jPanel1.add(jLabel1, BorderLayout.NORTH); // 将 JLabel 添加到北部

SpringLayout layout = new SpringLayout();

JPanel panel = new JPanel(layout);

JLabel label1 = new JLabel("Enter name:");

textField1 = new JTextField(20);

JLabel label2 = new JLabel("Enter password:");

textField2 = new JPasswordField(20);

JLabel label3 = new JLabel("Re-entered Password:");

textField3 = new JPasswordField(20);

// 添加组件到 SpringLayout 面板

panel.add(label1);

panel.add(textField1);

panel.add(label2);

panel.add(textField2);

panel.add(label3);

panel.add(textField3);

// 定义组件之间的约束关系

layout.putConstraint(SpringLayout.WEST, label1, 5, SpringLayout.WEST, panel);

layout.putConstraint(SpringLayout.NORTH, label1, 5, SpringLayout.NORTH, panel);

layout.putConstraint(SpringLayout.WEST, textField1, 64, SpringLayout.EAST, label1);

layout.putConstraint(SpringLayout.NORTH, textField1, 5, SpringLayout.NORTH, panel);

layout.putConstraint(SpringLayout.WEST, label2, 5, SpringLayout.WEST, panel);

layout.putConstraint(SpringLayout.NORTH, label2, 10, SpringLayout.SOUTH, textField1);

layout.putConstraint(SpringLayout.WEST, textField2, 40, SpringLayout.EAST, label2);

layout.putConstraint(SpringLayout.NORTH, textField2, 10, SpringLayout.SOUTH, textField1);

layout.putConstraint(SpringLayout.WEST, label3, 5, SpringLayout.WEST, panel);

layout.putConstraint(SpringLayout.NORTH, label3, 10, SpringLayout.SOUTH, textField2);

layout.putConstraint(SpringLayout.WEST, textField3, 5, SpringLayout.EAST, label3);

layout.putConstraint(SpringLayout.NORTH, textField3, 10, SpringLayout.SOUTH, textField2);

SpringLayout layout1 = new SpringLayout();

JPanel p1 = new JPanel(layout);

JButton jb1 = new JButton("Sign up");

jb1.addActionListener(new jb1action());

JButton jb2 = new JButton("Clean");

jb2.addActionListener(new jb2action());

JButton jb3 = new JButton("HomePage");

jb3.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

new HomePage();

}

});

panel.add(jb1);

panel.add(jb2);

panel.add(jb3);

layout.putConstraint(SpringLayout.WEST, jb1, 30, SpringLayout.WEST, panel);

layout.putConstraint(SpringLayout.NORTH, jb1, 10, SpringLayout.SOUTH, textField3);

layout.putConstraint(SpringLayout.WEST, jb2, 20, SpringLayout.EAST, jb1);

layout.putConstraint(SpringLayout.NORTH, jb2, 10, SpringLayout.SOUTH, textField3);

layout.putConstraint(SpringLayout.WEST, jb3, 20, SpringLayout.EAST, jb2);

layout.putConstraint(SpringLayout.NORTH, jb3, 10, SpringLayout.SOUTH, textField3);

jPanel1.add(panel, BorderLayout.CENTER); // 将 SpringLayout 的 panel 添加到中部

c1.add(jPanel1);

setVisible(true);

}

private class jb1action implements ActionListener{

@Override

public void actionPerformed(ActionEvent e) {

Map<String, String> UInfor = new HashMap<>();

String filePath = "D:\\jdk\\code\\GUI\\src\\StudentManagementSystem\\Register.txt";

try {

// 创建一个文件读取对象

FileReader fileReader = new FileReader(filePath);

BufferedReader bufferedReader = new BufferedReader(fileReader);

String line;

while ((line = bufferedReader.readLine()) != null) {

String[] parts = line.split(" : ");

if (parts.length == 2) {

String key = parts[0];

String value = parts[1];

UInfor.put(key, value);

}

bufferedReader.close();

} catch (IOException ex) {

System.out.println("读取文件时出现错误：" + ex.getMessage());

}

String getUseName = textField1.getText();

char[] ch1 = textField2.getPassword();

String getGetPassword1 = new String(ch1);

char[] ch2 = textField3.getPassword();

String getGetPassword2 = new String(ch2);

if (getGetPassword1.equals(getGetPassword2)){

JOptionPane.showMessageDialog(Register.this,"Register successfully!");

UInfor.put(getUseName,getGetPassword1);

File file = new File("D:\\jdk\\code\\GUI\\src\\StudentManagementSystem\\Register.txt");

FileWriter fileWriter = null;

try {

fileWriter = new FileWriter(file);

} catch (IOException ex) {

throw new RuntimeException(ex);

}

BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);

for (Map.Entry<String, String> entry : UInfor.entrySet()) {

String line = entry.getKey() + " : " + entry.getValue();

try {

bufferedWriter.write(line);

} catch (IOException ex) {

throw new RuntimeException(ex);

}

try {

bufferedWriter.newLine();

} catch (IOException ex) {

throw new RuntimeException(ex);

}

try {

bufferedWriter.close();

} catch (IOException ex) {

throw new RuntimeException(ex);

}

System.out.println("HashMap内容已写入文件：" + file);

dispose();

}else{

JOptionPane.showMessageDialog(Register.this,"Password and Re-entered Password do not match!");

textField2.setText("");

textField3.setText("");

}

private class jb2action implements ActionListener {

@Override

public void actionPerformed(ActionEvent e) {

textField1.setText("");

textField2.setText("");

textField3.setText("");

}

第二步：登陆界面

新建类：Login窗体设置，组件设置读取账号文本判断用户名和密码登陆成功，转换界面完整代码如下：

package StudentManagementSystem;

import javax.swing.*;

import java.awt.*;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.io.*;

import java.util.HashMap;

import java.util.Map;

public class Login extends JFrame {

public JTextField textField1;

public JPasswordField textField2;

public Login(){

setTitle("StudentManagementSystem");

setBounds(600, 200, 350, 300);

setDefaultCloseOperation(EXIT_ON_CLOSE);

Container c1 = getContentPane();

JPanel jPanel1 = new JPanel(new BorderLayout()); // 使用 BorderLayout

JLabel jLabel1 = new JLabel("Login");
