以下采用Spring配置方式
applicationContext.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" xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="makeBus" class="edu.hhxy.MakeBus" />
<bean id="makeJeep" class="edu.hhxy.MakeJeep" />
<bean id="makeKa" class="edu.hhxy.MakeKa" />
</beans>
采用junit进行测试（MakeCarClassTest）（通过接口接收getBean，接收的bean可以是接口的实现类，需要哪个实现类，就get哪个实现类，低耦合）
package edu.hhxy;import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;public class MakeCarClassTest {
@Test
public void getCar() {
ApplicationContext ctx = new ClassPathXmlApplicationContext(
"applicationContext.xml");
MakeCar makeCar = (MakeCar) ctx.getBean("makeBus");
System.out.println(makeCar);
}
}
