导入aop的maven依赖
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.6.12</version>
</dependency>
创建一个spring的XML文件编写aop配置
<?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:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
<!-- 装配切面类 -->
<bean id="mateDataServiceAspect" class="com.example.testproject.demo.aspect.MateDataServiceAspect"/>
<!--可以配置多个 aop:config 用于监听多个切面-->
<aop:config>
<aop:pointcut id="myExecution" expression="execution(* com.example.testproject.demo.controller.DemoController.test2(..))"/>
<aop:aspect ref="mateDataServiceAspect">
<aop:before method="before" pointcut-ref="myExecution"/>
<aop:after-returning method="afterReturning" pointcut-ref="myExecution" returning="methodResult"/>
</aop:aspect>
</aop:config>
</beans>
编写切面代码
public class MateDataServiceAspect {
public void before() {
System.out.println(">>>>>>>目录aop方法开始执行>>>>>>>>");
}
/**
* 方法执行完后调用
* @param joinPoint
* @param methodResult
*/
public void afterReturning(JoinPoint joinPoint, Object methodResult){
// 方法执行完返回的结果
System.out.println("监听方法的结果 " + methodResult);
// 获取方法的入参
Object[] args = joinPoint.getArgs();
List<Object> objects = Arrays.asList(args);
System.out.println("传入的参数:" + objects);
}
}
被监听的方法
调通接口测试
