Spring学习笔记，AOP操作基于配置文件xml管理AspectJ

一、创建被增强类Book和增强类BookProxy

package com.Spring5.AOPxml;

public class Book {
    public void add(){
        System.out.println("add... ... ...");
    }
}

package com.Spring5.AOPxml;

public class BookProxy {
    public void before(){
        System.out.println("before... ... ...");
    }
}

二、在xml文件中创建这两个类的对象并配置切入点

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
                            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
    <bean name="book" class="com.Spring5.AOPxml.Book"></bean>
    <bean name="bookproxy" class="com.Spring5.AOPxml.BookProxy"></bean>
    <aop:config>
        <aop:pointcut id="p" expression="execution(* com.Spring5.AOPxml.Book.add())"/>
        <aop:aspect ref="bookproxy">
            <aop:before method="before" pointcut-ref="p"></aop:before>
        </aop:aspect>
    </aop:config>

</beans>

三、测试

创建测试类

package com.Spring5.TestSpring;

import com.Spring5.AOP.User;
import com.Spring5.AOPxml.Book;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestAOP {
    @Test
    public void testaop(){
        ApplicationContext context=new ClassPathXmlApplicationContext("bean1.xml");
        Book book=context.getBean("book",Book.class);
        book.add();
    }
}

运行结果
