spring之通过实例工厂方法配置Bean

Car.java

package com.gong.spring.beans.factory;

public class Car {
    private String name;
    private double price;
    public String getName() {
        return name;
    }
    void setName(String name) {
        this.name = getPrice() {
         price;
    }
    void setPrice( price) {
        this.price =public Car(String name,super();
         name;
         price;
    }
    @Override
     String toString() {
        return "Car [name=" + name + ",price=" + price + "]";
    }
    
}

InstanceFactory.java

import java.util.HashMap;
 java.util.Map;

//实例工厂方法，先要创建工厂方法本身，再调用工厂的实例方法返回Bean的实例
 InstanceFactory {
    private Map<String,Car> cars = null;
     InstanceFactory() {
        cars = new HashMap<String,Car>();
        cars.put("baoma",1)">new Car("baoma",200000));
        cars.put("benchi",1)">new Car("benchi",300000));
    }
     Car getCar(String name) {
         cars.get(name);
    }
}

beans-factory.xml

    <!-- 配置工厂的实例 -->
    bean id="carFactory" class="com.gong.spring.beans.factory.InstanceFactory"></bean>
     通过实例工厂方法配置Bean ="car" factory-bean factory-method="getCar">
        constructor-arg value="baoma"constructor-arg</>

Main.java

 org.springframework.context.support.ClasspathXmlApplicationContext;

 Main {
    static  main(String[] args) {
        1.创建spring的IOC容器对象
        ClasspathXmlApplicationContext ctx = new ClasspathXmlApplicationContext("beans-factory.xml");
        2.从容器中获取Bean实例
        Car car = (Car) ctx.getBean("car");
        System.out.println(car.toString());
        ctx.close();
    }
}

输出：
