* spring代理嵌套方法调用不生效
*
* Spring AOP defaults to using standard JDK dynamic proxies for AOP
* proxies. This enables any interface (or set of interfaces) to be
* proxied.
*
* Spring AOP can also use CGLIB proxies. This is necessary to proxy
* classes rather than interfaces. CGLIB is used by default if a business
* object does not implement an interface. As it is good practice to
* program to interfaces rather than classes; business classes normally
* will implement one or more business interfaces. It is possible to force
* the use of CGLIB, in those (hopefully rare) cases where you need to
* advise a method that is not declared on an interface, or where you need
* to pass a proxied object to a method as a concrete type.
*
* It is important to grasp the fact that Spring AOP is proxy-based. See
* Section 11.6.1, “Understanding AOP proxies” for a thorough examination
* of exactly what this implementation detail actually means.
*
*
*
* 通过配置 <aop:aspectj-autoproxy proxy-target-class="true" />可以统一用CGLIB
* proxies。
