spring之通过FactoryBean配置Bean

Car.java

package com.gong.spring.beans.factorybean;

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 + "]";
    }
    
}

Carfactorybean.java

import org.springframework.beans.factory.factorybean;

class Carfactorybean implements factorybean<Car> {
    
    //返回Bean的对象
    @Override
    public Car getobject() throws Exception {
         Todo Auto-generated method stub
        return new Car(name,200000);
    }
    返回bean的类型
public Class<?> getobjectType() {
        return Car.;
    }
    是否是单例
boolean isSingleton() {
        true;
    }

}

beans-factorybean.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    bean id="car" class="com.gong.spring.beans.factorybean.Carfactorybean">
        property name="name" value="baoma"></property>
    </bean>
beans>

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-factorybean.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：
