自动创建了代理bean的作用就在于，简化代理bean的手动创建，免得代理bean在配置文件中堆积如山。
这里使用上一个例子的demo17、spring AOP通知——Pointcut、Advisor 创建代理bean的步骤如下：
第一步
修改bean配置文件
<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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <bean id="helloWorldService" class="com.main.AOP.autoCreateAdvice.HelloWorld"> <property name="name" value="jack"/> <property name="type" value="user"/> </bean> <!-- 环绕通知的bean --> <bean id="adviceAround" class="com.main.AOP.autoCreateAdvice.AdviceAroundService"></bean> <!-- 声明切入点和代理的关系的bean --> <bean id="helloWorldAdvisor" class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor"> <property name="mappedName" value="printName" /> <property name="advice" ref="adviceAround" /> </bean> <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> <property name="beanNames"> <list> <value>*Service</value> </list> </property> <property name="interceptorNames"> <list> <value>helloWorldAdvisor</value> </list> </property> </bean></beans>这时可以用helloWorldService的原始bean名来获取，就像这样：
HelloWorld helloworld = (HelloWorld)context.getBean("helloWorldService");自动创建Pointcut和Advisor
<bean id="helloWorldService" class="com.main.AOP.autoCreateAdvice.HelloWorld"> <property name="name" value="jack" /> <property name="type" value="user" /> </bean> <bean id="adviceAround" class="com.main.AOP.autoCreateAdvice.AdviceAroundService" /> <bean id="helloWorldAdvisor" class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor"> <property name="mappedName" value="printName" /> <property name="advice" ref="adviceAround" /> </bean> <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" />新闻热点
