本文详细介绍了如何进行Spring AOP的原生开发，从jar包和工程目录结构开始，逐步讲解了接口和实现类的定义，接着阐述了开发类的实现过程，并通过测试类验证了整个AOP功能的正确性，最终展示了操作结果。

jar包和工程目录
在这里插入图片描述

    <!--目标对象-->
<bean id="userService" class="com.baidu.oriAop.UserServiceImp"></bean>

    <!--增强-->
    <bean id="myMethodBeforeAdvice" class="com.baidu.oriAop.MyMethodBeforeAdvice"></bean>


    <!--将目标对象与增强进行结合-->
    <bean id="myRegexpMethodPointcutAdvisor"
          class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">

        <property name="advice" ref="myMethodBeforeAdvice"></property>
        <!--正则表达式-->
        <property name="patterns" value=".*add.*,.*del.*"></property>

  <!-- one- 原生开发代理对象-->

        <property name="interfaces" value="com.baidu.oriAop.UserServiceI"></property>

    </bean>-->



<!--two-通过bean名称自动创建代理-->
    <bean  class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">


    <property name="beanNames" value="*Service"></property>
        <property name="interceptorNames" value="myRegexpMethodPointcutAdvisor"></property>

    </bean>
</beans>

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
