創(chuàng)建Bean時，class屬性必須指定，此時為靜態(tài)工廠類。 factory-method指定靜態(tài)工廠方法名。

接口：

1 2 3

public?interface?Being { ????public?void?testBeing(); }

Dog類

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

public?class?Dog?implements?Being{ ????? ????private?String msg; ????public?void?setMsg(String msg) { ????????this.msg = msg; ????} ????@Override ????public?void?testBeing() { ????????System.out.println(msg +?" 狗愛啃骨頭"); ????????? ????} }

?

Cat類

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

public?class?Cat?implements?Being{ ????private?String msg; ????public?void?setMsg(String msg) { ????????this.msg = msg; ????} ????@Override ????public?void?testBeing() { ????????System.out.println(msg +?" 貓愛吃老鼠!"); ????????? ????} }

　

Bean里配置

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

<?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-3.0.xsd"> ????<bean id="dog"?class="com.springtest2.factory.BeingFactory" ????????factory-method="getBeing"> ????????<constructor-arg value="dog"?/> ????????<property name="msg"?value="我是狗"?/> ????</bean> ????<bean id="cat"?class="com.springtest2.factory.BeingFactory" ????????factory-method="getBeing"> ????????<constructor-arg value="cat"?/> ????????<property name="msg"?value="我是貓"?/> ????</bean> </beans>

　調(diào)用測試

1 2 3 4 5 6 7 8

private?static?void?testFactory(){ ????ApplicationContext context =?new?ClassPathXmlApplicationContext(new?String[]{"beans_factory.xml"}); ????Being b1 = context.getBean("dog", Being.class); ????b1.testBeing(); ????? ????Being b2 = context.getBean("cat", Being.class); ????b2.testBeing(); }
