My Tip 12: Wrong pointcut leads bean autowire exception

Advice的pointcut表达式如下：

1
@Around(value="execution(* com.fortinet.fortisales..*.logic..*.*Service*.*(..))")

导致了Spring装配bean错误：

我最后想到该问题的思路为：首先在“给property设定值的地方”设定断点，目的是查看运行时，究竟给它设了什么对象导致异常；结果发现给定的对象是一个Dynamic proxy实例，很奇怪，因为这个地方不需要设什么代理，为什么会生成一个动态代理对象呢？结果忽然想到是不是因为该类正好符合Advice的pointcut表达式，所以被代理了，检查之后发现果然如此！至此问题排除。

不过还有一个疑问：Advice会给每个“符合pointcut表达式的类”都产生动态代理吗？那会不会导致我遇到的这个问题呢？是的（2007-5-11）

另外想求证一下，如果advice设在interface的方法上，当实现该interface的该方法运行时，是否可以正常拦截。可以！！！！（2007-5-11）
