十三、AOP操作(AspectJ 配置文件)
作者:互联网
1. 创建两个类,增强类和被增强类,创建方法。
package com.demo.study_spring.aop.xml;
public class Book {
public void buy() {
System.out.println("buy ……");
}
}
package com.demo.study_spring.aop.xml;
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。
<?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: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/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">
<!--创建两个类的对象-->
<bean id="book" class="com.demo.study_spring.aop.xml.Book"></bean>
<bean id="bookProxy" class="com.demo.study_spring.aop.xml.BookProxy"></bean>
</beans>
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: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/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">
<!--创建两个类的对象-->
<bean id="book" class="com.demo.study_spring.aop.xml.Book"></bean>
<bean id="bookProxy" class="com.demo.study_spring.aop.xml.BookProxy"></bean>
<!--配置aop的增强-->
<aop:config>
<!--切入点-->
<aop:pointcut id="p" expression="execution(* com.demo.study_spring.aop.xml.Book.buy(..))"/>
<!--配置切面-->
<aop:aspect ref="bookProxy">
<!--配置增强作用在具体的方法上-->
<aop:before method="before" pointcut-ref="p" />
</aop:aspect>
</aop:config>
</beans>
