使用spring集成hibernate

hibernate中的hibernate.cfg.xml

<?xml version='1.0' encoding='UTF-8'?>
 2 <!DOCTYPE hibernate-configuration PUBLIC
 3           "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 4           "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
 5 <hibernate-configuration>
 6 
 7 <session-factory>
 8     <property name="connection.url">
 9         jdbc:oracle:thin:@localhost:1521:jbit
10     </property>
11     <property name="connection.username">rong</property>
12     <property name="connection.password">rong</property>
13     <property name="connection.driver_class">

15     </property>
16     <property name="dialect">
17         org.hibernate.dialect.OracleDialect
18     </property>
19     <property name="show_sql">true</property>
20     <property name="format_sql">true</property>
21     <mapping resource="cn/bdqn/jboa/entity/CheckResult.hbm.xml" />
22     <mapping resource="cn/bdqn/jboa/entity/ClaimVoucher.hbm.xml" />
23     <mapping resource="cn/bdqn/jboa/entity/ClaimVoucherDetail.hbm.xml" />
24     <mapping resource="cn/bdqn/jboa/entity/Department.hbm.xml" />
25     <mapping resource="cn/bdqn/jboa/entity/Dictionary.hbm.xml" />
26     <mapping resource="cn/bdqn/jboa/entity/Employee.hbm.xml" />
27     <mapping resource="cn/bdqn/jboa/entity/Position.hbm.xml" />
28 </session-factory>
29 
30 </hibernate-configuration>

更改后，调用事务就变得很简单了

public class UserDaoImpl extends HibernateDaoSupport implements UserDao{

    @Override
    public Employee findById(Serializable id) {
        // TODO Auto-generated method stub
        return this.getHibernateTemplate().get(Employee.class, id);
    }

}

创建接口类

public interface ClaimVoucherDao {
    public List<ClaimVoucher> find(int first,int pageSize);
}

回调机制

/**
 * 报销单类
 * @author Administrator
 *
 */
public class ClaimVoucherDaoImpl extends HibernateDaoSupport 
        　implements ClaimVoucherDao{

    @SuppressWarnings("unchecked")
    @Override
    public List<ClaimVoucher> find(final int first, final int pageSize) {
    

        return    this.getHibernateTemplate().executeFind(new HibernateCallback() {

            @Override
            public Object doInHibernate(Session arg0)
                    throws HibernateException, SQLException {
                // TODO Auto-generated method stub
                return arg0.createQuery(" from ClaimVoucher c")
                        .setFirstResult(first)
                        .setMaxResults(pageSize)
                        .list();
            }
        });
    }
}

在xml中添加dao的实例

1 <!-- dao -->
2     <bean id="userDao" class="cn.bdqn.jboa.dao.UserDaoImpl">
3         <property name="sessionFactory" ref="sessionFactory"></property>
4     </bean>
5     <bean id="claimVoucherDao" class="cn.bdqn.jboa.dao.ClaimVoucherDaoImpl">
6         <property name="sessionFactory" ref="sessionFactory"></property>
7     </bean>

测试类

public class testClaim {
    @Test
    public void test() {
        ApplicationContext ctx = new ClassPathXmlApplicationContext(
                "applicationContext.xml");
       ClaimVoucherDao claimVoucherDao = (ClaimVoucherDao) ctx.getBean("claimVoucherDao");
        System.out.println(claimVoucherDao.find(0, 3));
        System.out.println(claimVoucherDao.find(4, 3));
    }
}
