首先配置xml

<bean id="sessionFactory"
  class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
     <property name="annotatedClasses">
       <list>
         <value>com.chpn.model.User</value>
       </list>
     </property>
     <property name="hibernateProperties">
      <props>
         <prop key="hibernate.dialect">
         org.hibernate.dialect.MySQLDialect
         </prop>
         <prop key="hibernate.show_sql">
         true
         </prop>
    </props>

</property>
</bean>

建立实体类，加上annotation

@Entity
public class User {
int id;
String name;

@Id
@GeneratedValue
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;
}

}

在UserDaoImpl.java中写有关hibernate逻辑

@Component("user")
public class UserDAOImpl implements UserDAO {

private SessionFactory sessionFactory;

public SessionFactory getSessionFactory() {
return sessionFactory;
}

@Resource
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}

@Override
public void save(User u) {
   Session s = sessionFactory.openSession();
   s.beginTransaction();
   s.save(u);
   s.getTransaction().commit();

// TODO Auto-generated catch block

System.out.println("user save");
}

}

引入hibernate相关jar包
