原因：

ssh.xml的配置文件如下：

而定义ServiceDAO的实现类时，继承了HibernateDaoSupport，就必须使用 <property name="sessionFactory" ref="hsFactory"></property>
public class HibernateServiceDAO
extends HibernateDaoSupport implements ServiceDAO {....... }

但serviceDao组件只是引用了orderDao和itemDao，所以不需要继承HibernateDaoSupport

解决：

将public class HibernateServiceDAO
extends HibernateDaoSupport implements ServiceDAO {....... }

修改为：

public class HibernateServiceDAO implements ServiceDAO {....... }
