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());
}
