通过工厂方式配置bean

src\dayday\CarFactoryBean.java

package dayday;

import org.springframework.beans.factory.FactoryBean;

/**
 * Created by I am master on 2016/11/30.

//自定义的FactoryBean需要实现FactoryBean接口
public class CarFactoryBean implements FactoryBean<Car>{
    private String brand;
    public void setBrand(String brand){
        this.brand=brand;
    }
    @Override
    public Car getObject() throws Exception {
        return new Car(brand,"50w");
    }

    @Override
    public Class<?> getObjectType() {
        return Car.class;
    }

    @Override
    public boolean isSingleton() {
        return true;
    }
}

       <!--
         通过FactoryBean来配置Bean的实例
         class指向FactoryBean的全类名
         property:配置FactoryBean的属性，但实际返回的实例是FactoryBean的getObject()方法返回的实例
       -->
       <bean id="car" class="dayday.CarFactoryBean">
           <property name="brand" value="BMW"></property>
       </bean>
</beans>

运行结果
Car[carname=BMWcarValue=50w]
