spring之通过静态工厂方法配置Bean

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 + "]";
    }
    
}

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

//静态工厂方法：直接调用一个类的静态工厂方法就可以返回Bean的实例
 StaticFactory {
    static Map<String,Car> cars = new HashMap<String,Car>();
    static {
        cars.put("baoma",1)">new Car("baoma",200000));
        cars.put("benchi",1)">new Car("benchi",300000));
    }
     Car getCar(String name) {
         cars.get(name);
    }
}

    <!-- 通过静态工厂方法来配置Bean，不是配置静态工厂方法实例，而是配置Bean实例 -->
     class:指向静态工厂方法的全类名
         factory-method：指向静态工厂方法的名字
         constructor-arg：如果静态工厂方法需要传入参数，使用这个来配置参数 bean id="car" class="com.gong.spring.beans.factory.StaticFactory" factory-method="getCar">
        constructor-arg value="baoma"></constructor-arg>
    </bean>

        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();
    }
