避免客户端代码直接引用目标Bean
在Spring的ApplicationContext中为了避免客户端代码直接引用目标Bean，可以将目标Bean定义成内部Bean,我在其中是这样配置的
<bean id="service"
??/> -->
??</property>
??<property name="interceptorNames">
???<list>
????<value>authorityInterceptor</value>
???</list>
??</property>
?</bean>
出现如下错误：
Exception in thread "main" org.springframework.aop.AopInvocationException: AOP configuration seems to be invalid: tried calling method [public abstract void org.spring.aop.target.TestService.view()] on target [org.spring.aop.advice.AuthorityInterceptor@1193779]; nested exception is java.lang.IllegalArgumentException: object is not an instance of declaring class
