cglib第三方代理

Dec 29, 2016 // 大蚊子

不用接口，直接写类

//拦截对象

    public class UserDao {
        public void saveUser(){

System.out.println(“saveUser”);

        }

        public void updateUser(){

System.out.println(“updateUser”);

        }
    }

//后置增强

    public class AfterAdvice implements AfterReturningAdvice {

@Override

        public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable {

System.out.println(“日志保存”);

        }
    }

//测试类

    public class test {
        public static void main(String[] args) {
            ApplicationContext context=new ClassPathXmlApplicationContext("springAOP/springAopCglib/bean.xml");

UserDao userDao=context.getBean(“userProxy”,UserDao.class);

userDao.saveUser();

        }
    }

//增强（拦截所有的强求）
