代码：

1.配置文件

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"
    	xmlns:aop="http://www.springframework.org/schema/aop"
    	xmlns:tx="http://www.springframework.org/schema/tx"
    	xmlns:p="http://www.springframework.org/schema/p"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans 
    	http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
    	http://www.springframework.org/schema/tx 
    	http://www.springframework.org/schema/tx/spring-tx-2.0.xsd 
    	http://www.springframework.org/schema/aop 
    	http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">
    	
    	
    	<bean id="dataSource"
    		class="org.apache.commons.dbcp.BasicDataSource">
    		
    		<property name="driverClassName"
    			value="com.mysql.jdbc.Driver">
    		</property>
    		
    		<property name="url"
    			value="jdbc:mysql://localhost:3306/bookshop">
    		</property>
    		
    		<property name="username" value="root"></property>
    		
    		<property name="password" value="1234"></property>
    	</bean>
    	
    	
    	<bean id="sessionFactory"
    		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    		
    		<property name="dataSource">
    			<ref bean="dataSource" />
    		</property>
    		
    		<property name="hibernateProperties">
    			<props>
    			    
    				<prop key="hibernate.dialect">
    					org.hibernate.dialect.MySQLDialect
    				</prop>
    			</props>
    		</property>
    	</bean>
    	
    	
    	<bean id="userDAO" class="com.ssh2test1.dao.UserDAOImpl">	
    	  <property name="sessionFactory" ref="sessionFactory"/>
    	</bean>
    	
    	
    	<bean id="userBiz" class="com.ssh2test1.biz.UserBizImpl">
    	 <property name="userDAO" ref="userDAO" />
    	</bean>
    	
    </beans>

2.编写业务逻辑层

UserBiz.java

package com.ssh2test1.biz;
    
    import java.util.List;
    
    import com.ssh2test1.entity.Users;
    
    public interface UserBiz {
       public List login(Users condition);
    }

UserBizImpl.java

package com.ssh2test1.biz;
    
    import java.util.List;
    
    import com.ssh2test1.dao.UserDAO;
    import com.ssh2test1.entity.Users;
    
    public class UserBizImpl implements UserBiz {
    
    	//使用UserDAO接口声明对象，并添加set方法用于依赖注入
    	UserDAO userDAO;
    	
    	public void setUserDAO(UserDAO userDAO){
    		this.userDAO=userDAO;
    	}
    	public List login(Users condition) {
    		// TODO Auto-generated method stub
    		return userDAO.search(condition);
    	}
    
    }

3.编写数据访问层

UserDAO.java

package com.ssh2test1.dao;
    
    import java.util.List;
    
    import com.ssh2test1.entity.Users;
    
    public interface UserDAO {
      public List search(Users condition);
    }

UserDAOImpl.java

package com.ssh2test1.dao;
    
    import java.sql.SQLException;
    import java.util.List;
    
    import org.hibernate.Criteria;
    import org.hibernate.HibernateException;
    import org.hibernate.Session;
    import org.hibernate.criterion.Restrictions;
    import org.springframework.orm.hibernate3.HibernateCallback;
    import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
    
    import com.ssh2test1.entity.Users;
    
    public class UserDAOImpl extends HibernateDaoSupport implements UserDAO {
    	public List search(final Users condition) {
    		return super.getHibernateTemplate().executeFind(new HibernateCallback(){
    			public Object doInHibernate(Session session) throws HibernateException, SQLException {
    				// TODO 自动生成方法存根
    				Criteria c=session.createCriteria(Users.class);
    				if(condition!=null){
    					if(condition.getLoginName()!=null && !condition.getLoginName().equals("")){
    						c.add(Restrictions.eq("loginName", condition.getLoginName()));
    					}
    					if(condition.getLoginPwd()!=null && !condition.getLoginPwd().equals("")){
    						c.add(Restrictions.eq("loginPwd", condition.getLoginPwd()));
    					}
    				}
    				return c.list();
    			}
    		});		
    	}
    
    }

4.实体类及实体映射文件

Users.java

package com.ssh2test1.entity;
    
    import java.io.Serializable;
    
    public class Users implements Serializable {
    	private Integer id;
    	private String loginName;
    	private String loginPwd;
    	private String name;
    	private String address;
    	private String phone;
    	private String mail;
    	private Integer userRoleId;
    	private Integer userStateId;
    	public Users() {
    	}
    	public Users(String loginName, String loginPwd, String name,
    			String address, String phone, String mail, Integer userRoleId,
    			Integer userStateId) {
    		this.loginName = loginName;
    		this.loginPwd = loginPwd;
    		this.name = name;
    		this.address = address;
    		this.phone = phone;
    		this.mail = mail;
    		this.userRoleId = userRoleId;
    		this.userStateId = userStateId;
    	}
    	public Integer getId() {
    		return this.id;
    	}
    
    	public void setId(Integer id) {
    		this.id = id;
    	}
    
    	public String getLoginName() {
    		return this.loginName;
    	}
    
    	public void setLoginName(String loginName) {
    		this.loginName = loginName;
    	}
    
    	public String getLoginPwd() {
    		return this.loginPwd;
    	}
    
    	public void setLoginPwd(String loginPwd) {
    		this.loginPwd = loginPwd;
    	}
    
    	public String getName() {
    		return this.name;
    	}
    
    	public void setName(String name) {
    		this.name = name;
    	}
    
    	public String getAddress() {
    		return this.address;
    	}
    
    	public void setAddress(String address) {
    		this.address = address;
    	}
    
    	public String getPhone() {
    		return this.phone;
    	}
    
    	public void setPhone(String phone) {
    		this.phone = phone;
    	}
    
    	public String getMail() {
    		return this.mail;
    	}
    
    	public void setMail(String mail) {
    		this.mail = mail;
    	}
    
    	public Integer getUserRoleId() {
    		return this.userRoleId;
    	}
    
    	public void setUserRoleId(Integer userRoleId) {
    		this.userRoleId = userRoleId;
    	}
    
    	public Integer getUserStateId() {
    		return this.userStateId;
    	}
    
    	public void setUserStateId(Integer userStateId) {
    		this.userStateId = userStateId;
    	}
    }

Users.hbm.xml

<?xml version="1.0" encoding="utf-8"?>
    <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
    
    <hibernate-mapping>
        <class name="com.ssh2test1.entity.Users" table="users" catalog="bookshop">
            <id name="id" type="java.lang.Integer">
                <column name="Id" />
                <generator class="native"></generator>
            </id>
            <property name="loginName" type="java.lang.String">
                <column name="LoginName" length="50" />
            </property>
            <property name="loginPwd" type="java.lang.String">
                <column name="LoginPwd" length="16" />
            </property>
            <property name="name" type="java.lang.String">
                <column name="Name" length="16" />

            </property>
            <property name="phone" type="java.lang.String">
                <column name="Phone" length="16" />
            </property>
            <property name="mail" type="java.lang.String">
                <column name="Mail" length="16" />
            </property>
            <property name="userRoleId" type="java.lang.Integer">
                <column name="UserRoleId" />
            </property>
            <property name="userStateId" type="java.lang.Integer">
                <column name="UserStateId" />
            </property>
        </class>
    </hibernate-mapping>

5.测试类

TestSpringHibernate.java

package com.ssh2test1;
    
    import java.util.List;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    import com.ssh2test1.biz.UserBiz;
    import com.ssh2test1.entity.Users;
    
    public class TestSpringHibernate {
    	public static void main(String[] args) {
    		 //加载applicationContext.xml配置
    		ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
    		//获取配置中的实例
    		UserBiz userBiz =(UserBiz)context.getBean("userBiz");
    		Users conditon=new Users();
    		conditon.setLoginName("admin");
    		conditon.setLoginPwd("123456");
    		List list=userBiz.login(conditon);
    		if(list.size()>0){
    			System.out.println("登陆成功");
    		}
    		else{
    			System.out.println("登陆失败");
    		}		
    	}
    }
