接口和实现类

package com.baidu.oriAop;
    
    public interface UserServiceI {
        void add();
        void del();
        String findName();
    }

package com.baidu.oriAop;
    
    public class UserServiceImp implements UserServiceI {
    
        @Override
        public void add() {
            System.out.println("add---");
    
        }
    
        @Override
        public void del() {
            System.out.println("del---");
    
        }
    
        @Override
        public String findName() {
            System.out.println(" findName");
            return "Lisi";
        }
    }

开发类

package com.baidu.oriAop;
    
    import org.springframework.aop.MethodBeforeAdvice;
    import java.lang.reflect.Method;
    
    public class MyMethodBeforeAdvice implements MethodBeforeAdvice {
    
        @Override
        public void before(Method method, Object[] objects, Object o) throws Throwable {
            System.out.println("前置通知");
        }
    }

测试类

package com.baidu.oriAop;
    
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class TestOri {
    
        public static void main(String[] args) {
    
            ClassPathXmlApplicationContext applicationContext =
                    new ClassPathXmlApplicationContext("applicationContext.xml");
    
          /*  UserServiceI bean = (UserServiceI)applicationContext.getBean("proxy");  */
    
            UserServiceI bean = (UserServiceI)applicationContext.getBean("userService");
            bean.add();
            bean.del();
            bean.findName();
    
        }
    }

结果

//原生开发
          前置通知
    add---
    前置通知
    del---
     findName
    
    Process finished with exit code 0
