spring整合hibernate步骤如下：

1. 新建java项目
2. 导入jar包
3. 编写vo类

   @Entity
   @Table(name="t_user")
   public class User implements Serializable{
       @Id
       @GeneratedValue(strategy=GenerationType.AUTO)
       private int id;
       private String name;
       private int age;
       public int getId() {
           return id;
       }
       public void setId(int id) {
           this.id = id;
       }
       public String getName() {
           return name;
       }
       public void setName(String name) {
           this.name = name;
       }
       public int getAge() {
           return age;
       }
       public void setAge(int age) {
           this.age = age;
       }
   }

4. Hibernate映射文件

   <hibernate-mapping>
       <class name="cn.wh.vo.User" table="t_user">
           <id name="id">
               <generator class="native"></generator>
           </id>
           <property name="name"/>
           <property name="age"/>
       </class>
   </hibernate-mapping>

    

5. 编写hibernate的配置文件

   <hibernate-configuration>
   <session-factory>
       <property name="myeclipse.connection.profile">mysql</property>
       <property name="connection.url">
           jdbc:mysql://localhost:3306/hibernate4
       </property>
       <property name="connection.username">root</property>
       <property name="connection.password">1111</property>
       <property name="connection.driver_class">
           com.mysql.jdbc.Driver
       </property>
       <property name="hibernate.dialect">
           org.hibernate.dialect.MySQLDialect
       </property>
       <property name="hibernate.show_sql">true</property>
       <property name="hibernate.format_sql">true</property>
       <mapping resource="cn/sxt/vo/User.hbm.xml" />
   </session-factory>
   </hibernate-configuration>

6. 编写dao层

   public class UserDaoImpl implements UserDao{
       private SessionFactory sessionFactory;
       @Override
       public List<User> findAll() {
           return sessionFactory.openSession().createQuery("from User").list();
       }
       public void setSessionFactory(SessionFactory sessionFactory) {
           this.sessionFactory = sessionFactory;
       }
   }

    

7. 编写service

   public class UserServiceImpl implements UserService {
       private UserDao userDao;
       @Override
       public List<User> findAll() {
           return userDao.findAll();
       }
       public void setUserDao(UserDao userDao) {
           this.userDao = userDao;
       }
   }

    

8. 编写spring的配置文件

   <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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd 
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop.xsd">
       <!-- 整合hibernate第一种及配置方式 
       <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
           <property name="configLocation" value="classpath:hibernate.cfg.xml"/>
       </bean>
       -->
       <!-- 整合hibernate第二种方式 -->
       <!-- 配置数据源 -->
       <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
           <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
           <property name="url" value="jdbc:mysql://localhost:3306/hibernate4"/>
           <property name="username" value="root"/>
           <property name="password" value="1111"/>
       </bean>
       <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
           <property name="dataSource" ref="dataSource"/>
           <!-- 映射文件映射 
           <property name="mappingLocations">
               <list>
                   <value>classpath:cn/wh/vo/User.hbm.xml</value>
               </list>
           </property>
           -->
           <property name="annotatedClasses">
               <list>
                   <value>cn.wh.vo.User</value>
               </list>
           </property>
           <property name="hibernateProperties">
               <props>
                   <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                   <prop key="hibernate.show_sql">true</prop>
                   <prop key="hibernate.format_sql">true</prop>
               </props>
           </property>
       </bean>
       <bean id="userDao" class="cn.wh.dao.impl.UserDaoImpl">
           <property name="sessionFactory" ref="sessionFactory"></property>
       </bean> 
       <bean id="userService" class="cn.wh.service.impl.UserServiceImpl">
           <property name="userDao" ref="userDao"></property>
       </bean>
   </beans>

    

9. 测试：

   public class UserServiceTest {
       @Test
       public void testFindAll(){
           ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
           UserService userService = ac.getBean(UserService.class);
           List<User> list = userService.findAll();
           System.out.println(list.size());
       }
   }
