Spring BeanFactory和FactoryBean区别解析

测试类：

public class Test1 {
    ClassPathXmlApplicationContext xmlBeanFactory = null;
    @Before
    public void initXmlBeanFactory() {
      System.out.println("n========测试方法开始=======n");
      xmlBeanFactory = new ClassPathXmlApplicationContext("spring3.xml");
    }

    @After
    public void after() {
      System.out.println("n========测试方法结束=======n");
    }

    @Test
    public void test8() {
      System.out.println(xmlBeanFactory.getBean("colorFactoryBean"));
       System.out.println("===================");
      System.out.println(xmlBeanFactory.getBean("&colorFactoryBean"));
    
    }
}
