java学生信息管理系统MVC架构详解

本文实例为大家分享了java学生信息管理系统MVC架构，供大家参考，具体内容如下

一、项目结构

学生信息管理系统分三层进行实现。student.java主要提供数据，cotroller.java的功能是绑定试图和计算数据。Stuview.java用于单一的用来显示数据。

二、源码

1.1、Student 类

/*
 * @FileName: Student.class
 * @version:1.0
 * @author:nazi
 * 描述：模型层
 * */
import java.io.Serializable; 

/*
 * Summary: Student类实现序列化接口，用于对象的保存
 * @author：nazi
 * @version:1.0
 * */
public class Student implements Serializable {
  //序列化id
  private static final long serialVersionUID = 9088453456517873574L;
  int num;
  String name;
  String sex;
  int age;
  float grade; 

  public Student(int num ,String nameString,String sexString,int g,float f){
    this.num =num;
    name = nameString;
    sex =sexString;
    age =g;
    grade =f;
  } 

  public int getNum(){
    return num;
  } 

  public String getName(){
    return name;
  } 

  public String getSex(){
    return sex;
  } 

  public int getAge(){
    return age;
  } 

  public float getGrades(){
    return grade;
  } 

  public String toString(){
    return "姓名:"+name+"学号:"+num+"性别:"+sex+"年龄:"+age+"成绩:"+grade; 

  } 

}

1.2、Cotroller类

/*
 * 文件名： Cotroller.java
 * 描述：mvc中的c，用来管理模型层的数据
 * @authur:Nazi
 * function ：增、删、改、查、保存、更新
 * */
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.ArrayList;
import java.util.Iterator; 

/*
 * Cotroller类集中对ArrayList<Student>进行操作
 * @Author nazi
 * @version 1.0
 * */
public class Cotroller { 

  //student数据集合
  private ArrayList<Student> list; 

  public Cotroller(ArrayList<Student> l){
    this.list =l;
  } 

  /*
   * rturn a ArrayList<Student>
   * */
  public ArrayList<Student> getList()
  {
    return list;
  } 

  /*
   * 初始化Student数组
   * */
  public void setList(ArrayList<Student> list)
  {
    this.list = list;
  } 

  /*
   * add a student to the List
   * */
  public void add(Student s)
  {
    list.add(s);
  } 

  /*
   * remove the student from list
   * */
  public void remove(int id)
  {
    for(Iterator<Student> iter = list.iterator(); iter.hasNext();)
    {
      Student s = iter.next(); 

      if(s.getNum() == id)
      {
        list.remove(s);
      }
    }
  } 

  /*
   * print the specific student
   * */
  public String printAll(int i) {
     return list.get(i).toString();
  } 

  /*
   * 功能简述：将实现序列化后的对象写入到文件中。
   * 文件输出地址："/home/nazi/2.txt" 文件地址可以更改
   * */
  public void fileOt() throws FileNotFoundException{
    FileOutputStream fo = new FileOutputStream("/home/nazi/2.txt");
    try {
      ObjectOutputStream so = new ObjectOutputStream(fo);
      so.writeObject(list);
      so.close();
    } catch (IOException e) {
      e.printStackTrace();
    } 

  } 

  /*
   * function: 从指定路径读取文件，然后将对象状态进行赋值使用
   *
   * */
  @SuppressWarnings("unchecked")
  public void fileIn() throws FileNotFoundException{
    FileInputStream fi = new FileInputStream("/home/nazi/2.txt");
    try {
      ObjectInputStream si = new ObjectInputStream(fi);
      list = (ArrayList<Student>) si.readObject();
      si.close();
    } catch (IOException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    } catch (ClassNotFoundException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
  } 

}

1.3、StuView类

/*
 * FileName:StuView.class
 * 描述：以特定的方式展示数据
 * @Atuthor:nazi
 * @version:1.0
 * */
import java.awt.Font;
import java.awt.event.ActionEvent;

import javax.swing.JLabel;
import javax.swing.JTextArea;
import javax.swing.JTextField; 

/*
 * StuView 类用于展示数据
 * @author：nazi
 * @version:1.0
 * */
public class StuView {
  private static Cotroller cotroller;
  public static void main(String args[]){
    //创建管理者
    cotroller = new Cotroller(new ArrayList<Student>());
    //界面
    initFrame();
  } 

  /*
   * InitFrame()中含有各种类型的控件，以及控件所对应的事件处理步骤
   * */
  protected static void initFrame(){
      JFrame frame = new JFrame("学生信息管理系统");
      frame.setSize(600,600);
      frame.setLocation(500, 100);
      frame.setLayout(null);
      //生成组件
      final JTextField name = new JTextField();
      name.setBounds(79, 10, 103, 25);
      final JTextField num = new JTextField();
      num.setBounds(79, 53, 103, 25);
      final JTextField sex = new JTextField();
      sex.setBounds(79, 101, 103, 25);
      final JTextField age = new JTextField();
      age.setBounds(79, 161, 103, 25);
      final JTextField g1 = new JTextField();
      g1.setBounds(79, 216, 103, 25); 

      final JTextArea show = new JTextArea();
      show.setBounds(194, 12, 388, 274);
      frame.add(show);
      show.setFont(new Font("Serif",Font.BOLD,18));

          Student s1 = new Student(Integer.parseInt(num.getText()),name.getText(), sex.getText(),Integer.parseInt(age.getText()),Integer.parseInt(g1.getText()));
          //放到集合
          cotroller.getList().add(s1);
          //打印
          for(int i = 0;i<cotroller.getList().size();i++){
            show.append("\n");
            show.append(cotroller.printAll(i));
