spring +hibernate练习

1.实体类用的是orcal数据库中的Users表的方向工程

2、IUserDao.java

package com.yh.dao;

import com.yh.entity.Users;

public interface IUserDao {
     public Users findUser(Users us);
}

3、UserDao.java

package com.yh.dao.impl;

import java.util.List;

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

import com.yh.dao.IUserDao;
import com.yh.entity.Users;

public class UserDao extends HibernateDaoSupport implements IUserDao {
    

    public Users findUser(Users us) {
        // TODO Auto-generated method stub
        Users user=null;
        HibernateTemplate ht=this.getHibernateTemplate();
        List<Users> list=ht.findByExample(us);
        if(list.size()==0){return null;}
        return list.get(0);
    }

}

4、IUserBiz.java

package com.yh.biz;

import com.yh.entity.Users;

public interface IUserBiz {
   public Users login(Users us);
}

5、UserBiz.java

package com.yh.biz.impl;

import com.yh.biz.IUserBiz;
import com.yh.dao.IUserDao;
import com.yh.entity.Users;

public class UserBiz implements IUserBiz {
    public IUserDao userDao;
    
    public IUserDao getUserDao() {
        return userDao;
    }

    public void setUserDao(IUserDao userDao) {
        this.userDao = userDao;
    }

    public Users login(Users us) {
        // TODO Auto-generated method stub
        return userDao.findUser(us);
    }

}

6、SSHTest.java

package com.yh.Test;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.yh.biz.IUserBiz;
import com.yh.entity.Users;


public class SSHTest {
    @Test
    public void login(){
        ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
        IUserBiz biz=(IUserBiz) ac.getBean("userBiz");
        Users us=new Users();
        us.setName("sa");
        us.setPassword("123");
        Users u=biz.login(us);
        
        if(u!=null){
            System.out.println("登录成功！");
        }else{
            System.out.println("登录失败！");
        }
    }
}

7、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">

<!-- Generated by MyEclipse Hibernate Tools.                   -->
<hibernate-configuration>

    <session-factory>
        <property name="dialect">
            org.hibernate.dialect.Oracle9Dialect
        </property>
        <property name="connection.url">
            jdbc:oracle:thin:@172.16.17.158:1521:orcl

        <property name="connection.password">tiger</property>
        <property name="connection.driver_class">

        </property>
        <property name="myeclipse.connection.profile">yh</property>
        <property name="show_sql">true</property>
        <property name="format_sql">true</property>
        <mapping resource="com/yh/entity/Users.hbm.xml" />

    </session-factory>

</hibernate-configuration>

8、applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation"
            value="classpath:hibernate.cfg.xml">
        </property>
    </bean>
    
    <bean id="userDao" class="com.yh.dao.impl.UserDao">
