基于Struts2+Hibernate的学生信息管理系统实例
目录结构如下：
在mysql数据库中，建立一个数据库 stu,建立一张表stuinfo，如下图所示：
1.新建一个web project，命名为ch15，然后导入struts 2核心包和hibernate核心包，导入方法是：右击ch15这个项目，选择倒数第二项：,myeclipse，选择Add Struts 2...，导入hibernate的核心包也是一样。
2.首先要导入struts 2 核心包和hibernate核心包，但是struts 2 的核心包内的 antlr-2.x.x.jar包要删掉，删除方法是：window——>preferences——>Myeclipse——>Project Capabilitie——>Struts 2. 然后选中右边的antlr-2.x.x.jar包，选择右边的remove，就OK啦
3.在src下建立四个包，分别为addHibernateFile, Dao, PO, studentAction
4.addHibernateFile下的代码（HibernateSessionFactory.java）：
package addHibernateFile;
import javax.swing.JOptionPane;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateSessionFactory {
private static SessionFactory sessionFactory;
private static Configuration configuration=new Configuration();
public HibernateSessionFactory(){
}
static{
try{
Configuration configure = configuration.configure("hibernate.cfg.xml");
sessionFactory=configure.buildSessionFactory();
}catch(Exception e){
message("生成SessionFactoyr失败："+e);
}
}
public static Session getSession(){
return sessionFactory.openSession();
}
public static void message(String mess){
int type=JOptionPane.YES_NO_OPTION;
String title="提示信息";
JOptionPane.showMessageDialog(null, mess, title, type);
}
}
5.Dao包下面的代码（StudentDao.java）:
package Dao;
import addHibernateFile.HibernateSessionFactory;
import PO.Stuinfo;
import java.util.List;
import javax.swing.JOptionPane;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;
public class StudentDao {
private Transaction transaction;
private Session session;
private Query query;
public StudentDao(){
}
public boolean saveInfo(Stuinfo info){
try{
session=HibernateSessionFactory.getSession();
transaction=session.beginTransaction();
session.save(info);
transaction.commit();
session.close();
return true;
}catch(Exception e){
message("saveInfo.error:"+e);
e.printStackTrace();
return false;
}
}
public List findInfo(String type,Object value){
session=HibernateSessionFactory.getSession();
try{
transaction=session.beginTransaction();
String queryString="from Stuinfo as model where model."+type+"=?";
query=session.createQuery(queryString);
query.setParameter(0, value);
List list=query.list();
transaction.commit();
session.close();
return list;
}catch(Exception e){
message("findInfo.error:"+e);
e.printStackTrace();
return null;
}
}
public List findAllInfo(){
session=HibernateSessionFactory.getSession();
try{
transaction=session.beginTransaction();
String queryString="from Stuinfo";
query=session.createQuery(queryString);
List list=query.list();
transaction.commit();
session.close();
return list;
}catch(Exception e){
message("findInfo.error:"+e);
e.printStackTrace();
return null;
}
}
public boolean deleteInfo(String id){
try{
session=HibernateSessionFactory.getSession();
transaction=session.beginTransaction();
Stuinfo info=new Stuinfo();
info=(Stuinfo)session.get(Stuinfo.class, id);
session.delete(info);
transaction.commit();
session.close();
return true;
}catch(Exception e){
message("deleteInfo.error:"+e);
e.printStackTrace();
return false;
}
}
public boolean updateInfo(Stuinfo info){
try{
session=HibernateSessionFactory.getSession();
transaction=session.beginTransaction();
session.update(info);
transaction.commit();
session.close();
return true;
}catch(Exception e){
message("updateInfo.error:"+e);
e.printStackTrace();
return false;
}
}
public void message(String mess){
int type=JOptionPane.YES_NO_OPTION;
String title="提示信息";
JOptionPane.showMessageDialog(null, mess, title, type);
}
}
6.PO包下面的代码：
（1）Stuinfo.java
package PO;
public class Stuinfo implements java.io.Serializable {
private String id;
private String name;
private String sex;
private int age;
private float weight;
public String getId() {
return this.id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return this.sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public int getAge() {
return this.age;
}
public void setAge(int age) {
this.age = age;
