Spring-AOP操作（基于XML配置文件）

Spring-AOP操作（基于XML配置文件）

1.创建两个类，增强类和被增强类，创建方法

package com.orzjiangxiaoyu.aop.test3;

/**
 * @author orz
 * @create 2020-08-17 21:31
 */
public class Book {
    public void buy()
    {
        System.out.println("buy....");
    }
}

package com.orzjiangxiaoyu.aop.test3;

/**
 * @author orz
 * @create 2020-08-17 21:32
 */
public class BookProxy {
    public void before()
    {
        System.out.println("before...");
    }
}

2.在spring配置文件中创建两个类对象

3.在spring配置文件中配置切入点

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                           http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/aop
                           http://www.springframework.org/schema/aop/spring-aop.xsd
                           http://www.springframework.org/schema/context
                           http://www.springframework.org/schema/context/spring-context.xsd">

<!--    创建两个对像-->
    <bean id="book" class="com.orzjiangxiaoyu.aop.test3.Book"></bean>

    <bean id="bookproxy" class="com.orzjiangxiaoyu.aop.test3.BookProxy"></bean>
<!--    配置aop增强-->
    <aop:config >
<!--        切入点-->
        <aop:pointcut id="p" expression="execution(* com.orzjiangxiaoyu.aop.test3.Book.buy(..))"/>
<!--        配置切面-->
        <aop:aspect ref="bookproxy">
<!--            增强作用在具体的方法上-->
            <aop:before method="before" pointcut-ref="p"></aop:before>
        </aop:aspect>
    </aop:config>
</beans>

4.测试

package com.orzjiangxiaoyu.aop.test3;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * @author orz
 * @create 2020-08-17 21:38
 */
public class Test1 {
    @Test
    public void test1()
    {
        ApplicationContext context=new ClassPathXmlApplicationContext("bean3.xml");
        Book book = context.getBean("book", Book.class);
        book.buy();
    }
}

5.结果

before...
buy....
