三种实例化bean的方式
知识点：
【
1.使用类构造器实例化
<bean id=“orderService" 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" factory-bean="personServiceFactory" factory-method="createOrder"/>
public class OrderFactory {
public OrderServiceBean createOrder(){
return new OrderServiceBean();
}
}
】
