三种顾问，增强及Aspectj 的详解

 

///通知

 

此处的是实现类作为方法的增强

<!--1.目标对象--><!--2.要匹配的通知-->

    <bean id="beforeAdvice" class="cn.spring09aop01.MyBeforeAdvice"></bean>

<!--3经典 aop的 代理工厂bean-->

        <!--拦截的名称类型是字符串类型的 value=“beforeAdvice” 做怎么样的增强-->
        <property name="interceptorNames" value="beforeAdvice"></property>
    </bean>


</beans>

<!--02.增强：顾问正则匹配切入点-->
<bean id="beforeAdvisor" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
    <property name="advice" ref="beforeAdvice"></property>
    <property name="pattern" value=".*d.*"></property>

BeanName
<!--aop-->
    <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">

        <property name="beanNames" value="someservice"></property>
        <property name="interceptorNames" value="beforeAdvice"></property>

<!--02.增强：顾问正则匹配切入点-->

    <property name="advice" ref="beforeAdvice"></property>
    <property name="pattern" value=".*d.*"></property>
</bean>
在Xml中配置一个这个就是默认的自动代理自动代理生成器

<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"/>

 

 

@Test
public void ddaq() {
    //正则表达式匹配方法切入点
    ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext0.xml");
    ISomeService service = (ISomeService) ctx.getBean("proxyService");

    service.doSome();


}
这是我们昨天学习的，我也不知道怎么说。。。。
