ApplicationContext context;

public OneInterfaceImplTest() {

context = new ClassPathXmlApplicationContext("spring-ioc.xml");

}

@Test

public void test() {

OneInterface oneInterface1 = (OneInterface) context.getBean("oneInterface");

System.out.println(oneInterface1.hello2("123"));

// ApplicationContext context1 = new ClassPathXmlApplicationContext("spring-ioc2.xml");

OneInterface oneInterface2 = (OneInterface) context.getBean("oneInterface");

System.out.println(oneInterface2.hello2("123"));

}

配置项：<bean class="daoImpl.InjectionDAOImpl" id="InjectionDAO" scope="prototype"></bean>
