代理工厂生成器和顾问包装通知

1. 代理工厂生成器

顾问代理生成器，当我们声明好顾问后为目标对象生成代理对象。如果项目中存在多个代理对象的话，需要实例化许多的ProxyFactoryBean，我们可以使用顾 问 代理生成器来解决这个问题。  

  

        顾问代理生成器主要分两种

• 自动顾问代理生成器:DefaultAdvisorAutoProxyCreator
• 名称顾问代理生成器:BeanNameAutoProxyCreator

4.1 默认顾问代理生成器DefaultAdvisorAutoProxyCreater

4.1.1编写业务接口

public interface ISomeService {
    public void doSomething();

    public void say();
}

 

4.1.2编写业务接口实现类

public class ISomeServiceImpl implements ISomeService {
    @Override
    public void doSomething() {
        System.out.println("---------真实业务---------");
    }

    @Override
    public void say() {
        System.out.println("---------say方法---------");
    }
}

 

 

4.1.3编写切面了实现增强

public class MyAdvice implements MethodBeforeAdvice, AfterReturningAdvice {
    @Override
    public void before(Method method, Object[] objects, Object o) throws Throwable {
        System.out.println("===========前置增强===========");
    }

    @Override
    public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable {
        System.out.println("===========后置增强===========");
    }
}

 

 

4.1.4 编写applicationContext.xml文件

<!--将目标对象声明到Spring容器中-->
<bean id="doSomeService" class="cn.spring.advisortest.ISomeServiceImpl"></bean>

<bean id="beanTest" class="cn.spring.advisortest.BeanTest"></bean>
<!--将advice声明到容器中-->
<bean id="advice" class="cn.spring.advisortest.MyAdvice"></bean>

<!--配置顾问:包装通知-->
<bean id="advisor" class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor">
    <property name="advice" ref="advice"></property>
    <!--指定为say方法和doSomething方法实现增强-->
    <property name="mappedNames" value="doSomething,say"></property>
</bean>

<!--默认顾问自动代理生成器-->
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"></bean>

 

 

 

4.1.5 编写测试类

@org.junit.Test
public void test1() {
    ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
    ISomeService proxyfactory = (ISomeService) context.getBean("doSomeService");
    proxyfactory.doSomething();
    System.out.println();
    proxyfactory.say();
    System.out.println();
    BeanTest beanTest = (BeanTest) context.getBean("beanTest");
    beanTest.doSome();
}

 

4.2名称顾问代理生成器:BeanNameAutoProxyCreator

4.2.1编写业务接口

public interface ISomeService {
    public void doSomething();

    public void say();
}

 

4.2.2编写业务接口实现类

public class ISomeServiceImpl implements ISomeService {
    @Override
    public void doSomething() {
        System.out.println("---------真实业务---------");
    }

    @Override
    public void say() {
        System.out.println("---------say方法---------");
    }
}

 

 

4.2.3编写切面了实现增强

public class MyAdvice implements MethodBeforeAdvice, AfterReturningAdvice {
    @Override
    public void before(Method method, Object[] objects, Object o) throws Throwable {
        System.out.println("===========前置增强===========");
    }

    @Override
    public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable {
        System.out.println("===========后置增强===========");
    }
}

 

 

4.2.4 编写applicationContext.xml文件

<!--将目标对象声明到Spring容器中-->
<bean id="doSomeService" class="cn.spring.advisortest.ISomeServiceImpl"></bean>

<bean id="beanTest" class="cn.spring.advisortest.BeanTest"></bean>
<!--将advice声明到容器中-->
<bean id="advice" class="cn.spring.advisortest.MyAdvice"></bean>

<!--配置顾问:包装通知-->
<bean id="advisor" class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor">
    <property name="advice" ref="advice"></property>
    <!--指定为say方法和doSomething方法实现增强-->
    <property name="mappedNames" value="doSomething,say"></property>
</bean>

<!--BeanName自动代理生成器-->
<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
    <!--配置BeanName-->
    <property name="beanNames" value="doSomeService,beanTest"></property>
    <!--拦截顾问-->
    <property name="interceptorNames" value="advisor"></property>
</bean>

 

4.2.5编写测试类

@org.junit.Test
public void test1() {
    ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
    ISomeService proxyfactory = (ISomeService) context.getBean("doSomeService");
    proxyfactory.doSomething();
    System.out.println();
    proxyfactory.say();
    System.out.println();
    BeanTest beanTest = (BeanTest) context.getBean("beanTest");
    beanTest.doSome();
}

2. 顾问包装通知

通知(advice)是Spring中的一种比较简单的切面，只能将切面织入到目标类的所有方法中，而无法对指定方法进行增强

            顾问(advisor)是Spring提供的另外一种切面，可以织入到指定的方法中  接口 PointcutAdvisor

实现类:NameMatchMethodPointcutAdvisor(基于方法名称的增强顾问),RegexpMethodPointcutAdvice(基于正则表达式的增强顾问)

2.1  NameMatchMethodPointcutAdvisor

5.1.1编写业务接口

public interface ISomeService {
    public void doSomething();

    public void say();
}

    @Override
    public void doSomething() {
        System.out.println("---------真实业务---------");
    }

    @Override
    public void say() {
        System.out.println("---------say方法---------");
    }
}

 

 

5.1.3编写切面类实现增强

public class MyAdvice implements MethodBeforeAdvice, AfterReturningAdvice {
    @Override
    public void before(Method method, Object[] objects, Object o) throws Throwable {
        System.out.println("===========前置增强===========");
    }

    @Override
    public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable {
        System.out.println("===========后置增强===========");
    }
}

5.1.4编写applicationContext.xml文件

<bean id="doSomeService" class="cn.spring.advisortest.ISomeServiceImpl"></bean>

<bean id="beanTest" class="cn.spring.advisortest.BeanTest"></bean>
<!--将advice声明到容器中-->

    <property name="advice" ref="advice"></property>
    <!--指定为say方法和doSomething方法实现增强-->
    <property name="mappedNames" value="doSomething,say"></property>
</bean>

    System.out.println();
    proxyfactory.say();
    System.out.println();

    }

    @Override
    public void say() {
        System.out.println("---------say方法---------");
    }
}

 

 

5.2.3编写切面类实现增强
