SSH整合的程序

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.Transaction;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

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();

            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+"/";
%>

  <head>
    <base href="<%=basePath%>">

   <table border="1" bgcolor="palegreen">
 <tr>
 <td>id</td>
 <td>name</td>
