在Maven下用XML配置AOP步骤
1.导入jar包： <dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.9</version>
</dependency>
2.编写切面类： //切面类：功能的关注点
public class UsefulAspect {
public void sayHello(JoinPoint jp) {
System.out.println("hello");
}
public void sayBye() {
System.out.println("bye");
}
}
3.在XML中进行配置：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:aop="http://www.springframework.org/schema/aop" 5 xsi:schemaLocation="http://www.springframework.org/schema/beans 6 http://www.springframework.org/schema/beans/spring-beans.xsd 7 http://www.springframework.org/schema/context 8 http://www.springframework.org/schema/context/spring-context.xsd 9 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> 10 11 <context:component-scan base-package="com.yc" /> 12 <!-- 启用aspectJ的注解支持 --> 13 <context:annotation-config /> 14 15 <bean id="usefulAspect" class="com.yc.aspect.UsefulAspect"></bean> 16 17 <aop:config> 18 <aop:aspect id="myAspect" ref="usefulAspect"> 19 <aop:pointcut id="a" expression="execution(* com.yc.biz.impl.*.add*(..))"/> 20 <aop:before pointcut-ref="a" method="sayHello"/> 21 <aop:after pointcut-ref="a" method="sayBye"/> 22 </aop:aspect> 23 </aop:config> 24 </beans>
