hibernate中的hibernate.cfg.xml

 1 <?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">
14         oracle.jdbc.driver.OracleDriver
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

1 public class UserDaoImpl extends HibernateDaoSupport implements UserDao{
2
3     @Override
4     public Employee findById(Serializable id) {
5         // TODO Auto-generated method stub
6         return this.getHibernateTemplate().get(Employee.class, id);
7     }
8
9 }

创建接口类

1 public interface ClaimVoucherDao {
2     public List<ClaimVoucher> find(int first,int pageSize);
3 }

回调机制

 1 /**
 2  * 报销单类
 3  * @author Administrator
 4  *
 5  */
 6 public class ClaimVoucherDaoImpl extends HibernateDaoSupport         　implements ClaimVoucherDao{
 7
 8     @SuppressWarnings("unchecked")
 9     @Override
10     public List<ClaimVoucher> find(final int first, final int pageSize) {
11
12
13         return    this.getHibernateTemplate().executeFind(new HibernateCallback() {
14
15             @Override
16             public Object doInHibernate(Session arg0)
17                     throws HibernateException, SQLException {
18                 // TODO Auto-generated method stub
19                 return arg0.createQuery(" from ClaimVoucher c")
20                         .setFirstResult(first)
21                         .setMaxResults(pageSize)
22                         .list();
23             }
24         });
25     }
26 }

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));
    }
}
