工厂方法注入（静态和非静态）-优快云博客

本文介绍了Spring框架中两种工厂方法注入的实现方式：非静态和静态方法。通过具体示例展示了如何定义工厂类及配置XML来创建并配置Bean。

先看非静态的

先写一个简单工厂

package com.lbx.factory;

import com.lbx.model.Car;

/**
 * 这是非静态的工厂方法注入
 * @author Administrator
 *
 */
public class CarFactory {

	public Car createHongQiCar(){
		Car car = new Car();
		car.setName("红旗");
		car.setSpeed("200");
		return car;
	}
	
}

对应的bean.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

<bean id="carFactory" class="com.lbx.factory.CarFactory"></bean>
<bean id="car" factory-bean="carFactory" factory-method="createHongQiCar"></bean>

</beans>

再看静态的(无需依赖工厂的bean)

工厂类

package com.lbx.factory;

import com.lbx.model.Car;
/**
 * 这是静态的工厂方法注入
 * @author Administrator
 *
 */
public class CarFactory2 {

	public static Car createHongQiCar(){
		Car car = new Car();
		car.setName("红旗");
		car.setSpeed("200");
		return car;
	}
	
}

对应的bean2.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

<bean id="car" class="com.lbx.factory.CarFactory2" factory-method="createHongQiCar"></bean>

</beans>
