Spring------关于代理

自动装配（基于顾问）

someService类

public class someService {
    public void  list(){
        System.out.println("list");
    }
    public  void add(){ System.out.println("add"); }
}

前置增强类

public class MyBeforeAdvice implements MethodBeforeAdvice {
    @Override
    public void before(Method method, Object[] args, Object target) throws Throwable {
        System.out.println("before=============");
    }
}

xml配置

<bean id="someService" class="cn.Day11.someService"></bean>
    <!--增强-->
<bean id="myBeforeAdvice" class="cn.Day11.MyBeforeAdvice"></bean>
    <!--顾问-->
    <bean id="myAdvisor" class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor">
        <property name="advice" ref="myBeforeAdvice"></property>
        <property name="mappedNames" value="*li*"></property>
    </bean>

<!--自动代理-->
    <bean id="proxyService" class="org.springframework.aop.framework.ProxyFactoryBean">
        <property name="target" ref="someService"></property>
        <property name="interceptorNames" value="myAdvisor"></property>
    </bean>

测试类

public class Test11 {
    @Test
    public void zyy(){
        ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContextDay11.xml");
        someService service=(someService)ctx.getBean("proxyService");
        service.list();
        service.add();
    }

测试结果

自动代理

 前两个类相同

xml文件（也可以用顾问）

<bean id="someService" class="cn.Day12.someService"></bean>
    <!--增强-->
<bean id="myBeforeAdvice" class="cn.Day12.MyBeforeAdvice"></bean>
    <!--顾问-->
    <bean id="myAdvisor" class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor">
        <property name="advice" ref="myBeforeAdvice"></property>
        <property name="mappedNames" value="*li*"></property>
    </bean>


    <bean id="proxyService" class="org.springframework.aop.framework.ProxyFactoryBean">
        <property name="target" ref="someService"></property>
        <property name="interceptorNames" value="myAdvisor"></property>
    </bean>

    <!--自动代理-->
    <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"></bean>

测试类

public class Test12 {
    @Test
    public void De(){
            ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContextDay12.xml");
            someService service=(someService)ctx.getBean("someService");
            service.list();
            service.add();

    }

}
