Spring_通过Bean的Factory配置Bean

package com.tanlei.bean.FactoryBean;

import org.springframework.beans.factory.FactoryBean;

public class CarFactoryBean  implements FactoryBean<Car>{

    private String brand;

    public void setBrand(String brand) {

        this.brand = brand;

    }

    //返回bean的对象

    @Override

    public Car getObject() throws Exception {

        // TODO Auto-generated method stub

        return new Car(brand,500000);

    }

    /**

     * 返回Bean的类型

     */

    @Override

    public Class<?> getObjectType() {

        // TODO Auto-generated method stub

        return Car.class;

    }

    @Override

    public boolean isSingleton() {

        // TODO Auto-generated method stub

        return true;

    }

}

//自定义的FactoryBean需要实现FactoryBean接口

<!--
通过FactoryBean来配置Bean的实例
class:指向FactoryBean的全类名
property:配置的是FactoryBean的属性,但实际返回的实例是FactoryBean的getObject()方法返回的实例
