JavaSwing+Hibernate实现简单的学生信息管理系统

Hibernate对JDBC进行了非常轻量级的对象封装，利用Hibernate框架可以让我们用面向对象的思想来操作数据对象。以下将说明一个简单的学生信息管理系统例子，结合了Java图形界面和hibernate框架。这里将不再说明hibernate的配置，请读者先自行配好,下图是运行效果。

**1.首先是数据持久层，即写好JavaBean类** Student.java package com.edu.entity; public class Student { private Integer id;//对象标志符 private Integer no;//学号 private String name;//姓名 private String sex;//性别 private String dept;//所在系别 private Integer age;//年龄 private String address;//地址 public Student(){} public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public Integer getNo() { return no; } public void setNo(Integer no) { this.no = no; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public String getDept() { return dept; } public void setDept(String dept) { this.dept = dept; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } } **2.利用hiberante的eclipse插件可以很方便生成对象文件，右击Student类，new->others->hibernate，选择相关选项，如下图所示**

按Finish按钮即可生成 Student.hbm.xml <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2017-5-17 19:57:33 by Hibernate Tools 3.5.0.Final --> <hibernate-mapping> <class name="com.edu.entity.Student" table="STUDENT"> <id name="id" type="java.lang.Integer"> <column name="ID" /> <generator class="native" /> </id> <property name="no" type="java.lang.Integer"> <column name="NO" /> </property> <property name="name" type="java.lang.String"> <column name="NAME" /> </property> <property name="sex" type="java.lang.String"> <column name="SEX" /> </property> <property name="dept" type="java.lang.String"> <column name="DEPT" /> </property> <property name="age" type="java.lang.Integer"> <column name="AGE" /> </property> <property name="address" type="java.lang.String"> <column name="ADDRESS" /> </property> </class> </hibernate-mapping> **3.配置Hibernate.cfg.xml** <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://localhost:3306/homework?useUnicode=true&characterEncoding=utf-8</property> <property name="connection.username">root</property> <property name="connection.password">root</property> <property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> <property name="hbm2ddl.auto">update</property> <property name="show_sql">true</property> <property name="format_sql">true</property> <mapping resource="com/edu/entity/Student.hbm.xml"/> </session-factory> </hibernate-configuration> **4.编写Hibernate工具类HibernateUtils.java** package com.edu.entity; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.boot.registry.StandardServiceRegistryBuilder; import org.hibernate.cfg.Configuration; import org.hibernate.service.ServiceRegistry; public class HibernateUtils { /* *读取Hibernate.cfg.xml文件 */ private static SessionFactory factory; private static ThreadLocal threadLocal=new ThreadLocal(); static { try { //读取hibernate.cfg.xml文件 Configuration cfg = new Configuration().configure(); //建立SessionFactory ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder() .applySettings(cfg.getProperties()).build(); factory = cfg.buildSessionFactory(serviceRegistry); }catch(Exception e) { e.printStackTrace(); } } public HibernateUtils() { // TODO Auto-generated constructor stub } /* *打开Session */ public static Session getSession() { Session session=(Session)threadLocal.get(); if(session==null){ session=factory.openSession(); threadLocal.set(session); } return session; } /* *关闭Session */ public static void closeSession() { Session s=(Session)threadLocal.get(); if(s!=null){ s.close(); threadLocal.set(null); } } public static SessionFactory getSessionFactory() { return factory; } } **5.最后，编写主类ImageMain.java.这里完成各种操作，包括图形界面的实现** package com.edu.entity; import javax.swing.*; import javax.swing.border.TitledBorder; import javax.swing.event.ChangeEvent; import javax.swing.table.DefaultTableModel; import java.awt.*; import java.util.List; import java.awt.event.*; import java.util.*; public class ImageMain extends JFrame implements ActionListener{ private LogPane log; JSplitPane vsplitPane; static JPanel controlPane;

String[] columns = {"序号","学号","姓名","性别","年龄","专业","地址"}; public ImageMain(){ super("Author@夜空--学生信息管理系统"); try { UIManager .setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel"); } catch (Exception e) { e.printStackTrace(); } try { init(); } catch (Exception e) { // TODO 自动生成的 catch 块 log.addLog(e.toString()); } } private void setBorder(TitledBorder titledBorder) { // TODO Auto-generated method stub } public void init(){ initTable(); initUI(); initListener(); setSize(800,650); setLocationRelativeTo(null); setBackground(Color.LIGHT_GRAY); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setVisible(true); // setBorder(new TitledBorder("学")); setResizable(false); } public void initTable(){ columnsName=new Vector(); for(int i=0;i<columns.length;i++){ columnsName.add(columns[i]); } vector=new Vector<Vector>(); tableModel=new DefaultTableModel(vector,columnsName); table = new JTable(tableModel); table.setRowHeight(30); } public void initUI(){ queryButton=new JButton("查询"); newButton=new JButton("新增"); insertButton=new JButton("插入"); updateButton=new JButton("更改"); deleteButton=new JButton("删除"); queryButton.addActionListener(this); newButton.addActionListener(this); insertButton.addActionListener(this); updateButton.addActionListener(this); deleteButton.addActionListener(this); JPanel pane=new JPanel(); pane.add(new JLabel("学生信息管理系统")); pane.setLayout(new BorderLayout()); selectPane=new JPanel(new BorderLayout()); deletePane=new JPanel(); updatePane=new JPanel(); insertPane=new JPanel();

tabPane=new JTabbedPane(JTabbedPane.TOP); tabPane.add("查询",selectPane); tabPane.add("插入",insertPane); tabPane.add("更新",updatePane); tabPane.add("删除",deletePane); controlPane.add(tabPane,BorderLayout.CENTER); log=LogPane.getLog(); log.addLog("欢迎来到学生信息管理系统!",Color.blue); vsplitPane=new JSplitPane(JSplitPane.VERTICAL_SPLIT); vsplitPane.setTopComponent(new JScrollPane(controlPane)); vsplitPane.setBottomComponent(log); vsplitPane.setDividerLocation(400); vsplitPane.setEnabled(false); add(vsplitPane); } public void initListener(){ tabPane.addChangeListener(new javax.swing.event.ChangeListener() { @Override public void stateChanged(ChangeEvent e) { // TODO Auto-generated method stub JTabbedPane tabbedPane = (JTabbedPane)e.getSource(); int selectedIndex = tabbedPane.getSelectedIndex(); switch(selectedIndex){ case 0: log.addLog("进入查询记录面板"); break; case 1: log.addLog("进入插入记录面板"); break; case 2: log.addLog("进入更新记录面板"); break; case 3: log.addLog("进入删除记录面板");
