对应的实现接口业务对象的代码如下：
　OrderDAOImpl.java
   package com.trx.db.dao;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.trx.db.entity.Order; //基于篇幅Order类省略掉了

public class OrderDAOImpl extends HibernateDaoSupport implements IOrderDAO{

   public void insertOrder(Order order) {

       this.getHibernateTemplate().save(order);

   }

}

ItemDAOImpl.java

package com.trx.db.dao;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.trx.db.entity.Item;//基于篇幅Item类省略掉了

public class ItemDAOImpl extends HibernateDaoSupport implements IItemDAO{

   public void insertItem(Item item) {

       this.getHibernateTemplate().save(item);

   }
