Car.java
package com.gong.spring.beans.factorybean; public class Car { private String name; private double price; public String getName() { return name; } public void setName(String name) { this.name = name; } public double getPrice() { return price; } public void setPrice(double price) { this.price = price; } public Car(String name, double price) { super(); this.name = name; this.price = price; } @Override public String toString() { return "Car [name=" + name + ", price=" + price + "]"; } }
Carfactorybean.java
package com.gong.spring.beans.factorybean; import org.springframework.beans.factory.factorybean; public class Carfactorybean implements factorybean { private String name; public void setName(String name) { this.name = name; } //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 @Override public Class> getobjectType() { // Todo Auto-generated method stub return Car.class; } //是否是单例 @Override public boolean isSingleton() { // Todo Auto-generated method stub return true; } }
beans-factorybean.xml
Main.java
package com.gong.spring.beans.factorybean; import org.springframework.context.support.ClasspathXmlApplicationContext; public class Main { public static void 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：
