本文介绍了一个基于Hibernate框架的宠物管理系统的设计与实现过程。系统包括利用DAO模式进行数据访问、Service层处理业务逻辑、Action层处理用户请求及JSP页面展示等功能模块。通过此系统可以完成宠物信息的增删改查等操作。

util包配置

package com.util;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class DaoUtil {
public static final SessionFactory sf = new Configuration().configure().buildSessionFactory();
}

dao包方法

package com.dao;

import java.util.List;

import com.bawei.wang.bean.Dog;
import com.bawei.wang.bean.DogType;

public interface DogDao {
public void register(Dog dog);
public List<DogType> selectDogType();
public List<Dog> getDogList();
public void delete(Dog dog);
public Dog selectById(Dog dog);
public void update(Dog dog);
}

dao层实现类

package com.bawei.wang.dao;

import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.bawei.wang.bean.Dog;
import com.bawei.wang.bean.DogType;
import com.bawei.wang.util.DaoUtil;

public class DogDaoImpl extends HibernateDaoSupport implements DogDao{
   Session session = null;
   Transaction transaction = null;
   @SuppressWarnings("unchecked")
   @Override
   public List<Dog> getDogList() {
   List<Dog>   list=this.getHibernateTemplate().find("from Dog");
       return list;

   }
   /*@Override
   public List<Dog> getDogList() {
       Session session=DaoUtil.sf.openSession();
       Query query=session.createQuery("from Dog");
       List<Dog> list=query.list();
       return list;
   }*/
   @Override
   public void register(Dog dog) {
       try {
           session = DaoUtil.sf.openSession();
           transaction = session.beginTransaction();
           session.save(dog);
           transaction.commit();
       } catch (HibernateException e) {
           transaction.rollback();
           e.getStackTrace();
       } finally {
           session.close();
       }

   }
   @Override
   public List<DogType> selectDogType() {
       List<DogType> list = null;
       session = DaoUtil.sf.openSession();
       Query query = session.createQuery("from DogType");
       list = query.list();
       return list;
   }

   @Override
   public void delete(Dog dog) {
       Session session=DaoUtil.sf.openSession();
       try {

           transaction = session.beginTransaction();
           session.delete(dog);
           transaction.commit();
       } catch (Exception e) {
           e.printStackTrace();
       } finally {
           session.close();
       }
   }
   @Override
   public Dog selectById(Dog dog) {
       session = DaoUtil.sf.openSession();
       Dog d = null;
       try {
           d = (Dog) session.get(Dog.class, dog.getId());
       } catch (Exception e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       } finally {
           session.close();
       }
       return d;
   }

   @Override
   public void update(Dog dog) {
       session = DaoUtil.sf.openSession();
       try {
           transaction = session.beginTransaction();
           session.update(dog);
           transaction.commit();
       } catch (Exception e) {
           e.printStackTrace();
       } finally {
           session.close();
       }
   }

}

service层实现类

package com.service;

import java.util.List;

import com..bean.Dog;
import com..bean.DogType;
import com..dao.DogDao;

public class DogServiceImpl implements DogService{
private DogDao dao;

   @Override
   public List<Dog> getDogList() {
       // TODO Auto-generated method stub
       return dao.getDogList();
   }

   public DogDao getDao() {
       return dao;
   }

   public void setDao(DogDao dao) {
       this.dao = dao;
   }

   @Override
   public void register(Dog dog) {
       dao.register(dog);
   }

   @Override
   public List<DogType> selectDogType() {
       // TODO Auto-generated method stub
       return dao.selectDogType();
   }

   @Override
   public void delete(Dog dog) {
       dao.delete(dog);
   }

   @Override
   public Dog selectById(Dog dog) {
       // TODO Auto-generated method stub
       return dao.selectById(dog);
   }

   @Override
   public void update(Dog dog) {
       dao.update(dog);
   }





}

action类的方法

package com.bawei.wang.action;

import java.util.List;

import com.bean.Dog;
import com.service.DogService;

public class DogAction {
public DogService service;
public List list;
public Dog dog;

public String getDogList(){
   System.out.println("进入查询方法");
   list=service.getDogList();
return "listDog";
}
public String register() {
   System.out.println("进入添加方法");
   service.register(dog);
   return getDogList();
}
public String delete() {
   System.out.println("进入删除方法");
   service.delete(dog);
   return getDogList();
}
public String update() {
   System.out.println("进入修改方法");
   service.update(dog);
   dog.setName("");
   return getDogList();
}
public String selectById() {
   dog = service.selectById(dog);
   list = service.selectDogType();
   return "update";
}
public Dog getDog() {
   return dog;
}

public void setDog(Dog dog) {
   this.dog = dog;
}

public DogService getService() {
   return service;
}
public void setService(DogService service) {
   this.service = service;
}
public List getList() {
   return list;
}
public void setList(List list) {
   this.list = list;
}

}

查询界面JSP的显示

在展示界面的时候要有一个list集合查出来展示

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <base href="<%=basePath%>">
    <title>My JSP 'index.jsp' starting page</title>
<body>
   <table border="1" bgcolor="palegreen">
<tr>
<td>id</td>
<td>name</td>
<td>age</td>
<td>love</td>
<td>health</td>
<td>品种id</td>
<td>品种类型</td>
<td>操作</td>
</tr>
   <c:forEach items="${list }" var="dog">
   <tr>
   <td>${dog.id }</td>
   <td>${dog.name}</td>
   <td>${dog.age }</td>
   <td>${dog.love }</td>
   <td>${dog.health }</td>
   <td>${dog.dogType.tid }</td>
   <td>${dog.dogType.tname }</td>
   <td><a href="DogAction!delete.action?dog.id=${dog.id }">删除</a>
   <a href="insert.jsp">添加</a>
    </td>
   </tr>

   </c:forEach>

   </table>

<br>
</body>
</html>

添加界面的JSP

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <base href="<%=basePath%>">
    <title>这是添加界面</title>
</head>
<body>
    <form action="DogAction!register.action" method="post">
名字：<input type="text" id="name" name="dog.name" />
年龄：<input type="text" id="age" name="dog.age" >
