Spring提供的资源访问和加载类Resource

1、Spring提供的资源访问和加载类Resource

 
2、applicationContext.xml中的配置信息

 

3、测试代码

@Test
public void testResource() {
	// 1.通过ClassPathResource加载配置文件
	Resource resource = new ClassPathResource("applicationContext.xml");
	XmlBeanFactory xmlBeanFactory = new XmlBeanFactory(resource);
	UserBean userBean = (UserBean) xmlBeanFactory.getBean("userBean");
	// 输出：keke
	System.out.println(userBean.getUsername());
	// 2.通过FileSystemResource加载配置文件
	Resource resource2 = new FileSystemResource(
			"D:/code/02-tanzhouedu/tz_springmvc/src/applicationContext.xml");
	XmlBeanFactory xmlBeanFactory2 = new XmlBeanFactory(resource2);
	UserBean userBean2 = (UserBean) xmlBeanFactory.getBean("userBean");
	// 输出：keke
	System.out.println(userBean2.getUsername());
}
