#### 使用XmlBeanFactory报了一个横线 ####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTAzMTYxODg_size_16_color_FFFFFF_t_70]

#### 方法1 组合的方式 ####

public static void main(String[] args) {
    		Resource resource = new ClassPathResource("bean.xml");
    		BeanFactory factory = new DefaultListableBeanFactory();
    		BeanDefinitionReader bdr = new XmlBeanDefinitionReader((BeanDefinitionRegistry) factory);
    		bdr.loadBeanDefinitions(resource);
    		Student student = factory.getBean("stu", Student.class);
    		System.out.printf("。。。。。。" + student);
    	}

### 方法2 ClassPathXmlApplicationContext ###

ApplicationContext sc = new ClassPathXmlApplicationContext("bean.xml");
    		Student student = sc.getBean("stu", Student.class);
    		System.out.printf("。。。。。。" + student);

### 方法3 FileSystemXmlApplicationContext ###

ApplicationContext factory=new FileSystemXmlApplicationContext("bean.xml");

#### 方法4 WebApplicationContextUtils获取（web项目使用） ####

ServletContext servletContext = request.getSession().getServletContext(); 
        ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext );
