使用Junit进行单元测试，首先引入Junit的jar，配置如下。
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:factory_bean.xml")
public class MainApp {
@Test
public void demon1() {
ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"factory_bean.xml"});
Person p1 = context.getBean("chinese",Person.class);
System.out.println(p1.sayHello("Marry"));
System.out.println(p1.sayGoodBye("Marry"));
Person p2 = context.getBean("chinese",Person.class);
System.out.println(p2 == p1);
System.out.println(context.getBean("&chinese"));
}
}
