下文笔者着重讲述AOP不起作用的相关说明,如下所示:
定义Aspect
package com.java265.aop; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Pointcut; import org.springframework.stereotype.Component; @Aspect @Component public class FunctionMonitor { @Pointcut("execution(public * com.java265.controller.*.*(..))") private void pointCutMethod() { } //声明环绕通知 @Around("pointCutMethod()") public Object doAround(ProceedingJoinPoint pt) throws Throwable { long begin = System.nanoTime(); Object o = pt.proceed(); long end = System.nanoTime(); String s = pt.getTarget().getClass()+"."+pt.getSignature().getName()+"----"+(end-begin)/1000000; System.out.println(s); System.out.println("aop---end"); return o; } }
配置xml--springmvc.xml
<?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" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd "> <!--设置包扫描器--> <context:component-scan base-package="com.java265.controller"> </context:component-scan> <!--设置注解驱动--> <mvc:annotation-driven /> <aop:aspectj-autoproxy proxy-target-class="true" /> <bean class="com.java265.aop.FunctionMonitor"/> <!--设置视图解析器--> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/admin/"></property> <property name="suffix" value=".jsp"></property> </bean> <!--设置文件上传核心组件--> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> </bean> </beans>
当AOP不起作用时,请着重注意以下几个地方,如:
<!--设置包扫描器--> <context:component-scan base-package="com.java265.controller"> </context:component-scan> <!--设置注解驱动--> <mvc:annotation-driven /> <aop:aspectj-autoproxy proxy-target-class="true" /> <bean class="com.java265.aop.FunctionMonitor"/>
