知识点：
【
1.使用类构造器实例化
<bean id=“orderService" class="cn.itcast.OrderServiceBean"/>
2.使用静态工厂方法实例化
<bean id="personService" class="cn.itcast.service.OrderFactory" factory-method="createOrder"/>
public class OrderFactory {
public static OrderServiceBean createOrder(){
return new OrderServiceBean();
}
}
3.使用实例工厂方法实例化:
<bean id="personServiceFactory" class="cn.itcast.service.OrderFactory"/>
<bean id="personService" factory-bean="personServiceFactory" factory-method="createOrder"/>
public class OrderFactory {
public OrderServiceBean createOrder(){
return new OrderServiceBean();
}
}
