/* 需要在Spring配置文件中开启aop的自动代理 */

单元测试&运行结果

@Test
public void five() {
    //加载Spring配置文件
    ApplicationContext context = new ClassPathXmlApplicationContext("classpath:spring/spring-application.xml");
    //通过Spring上下文对象获取OneService对象实例
    OneService oneService = (OneService) context.getBean("oneService");
    //执行one()方法
    oneService.one();
}
