使用AspectJ的Spring MVC

Your around advice does not return the result of pjp.proceed(). That is the
return value of the advised method and must be returned by the advice!
Otherwise you are turning the advised method into a void as well.

public **Object** log(final ProceedingJoinPoint pjp) {...    try {        **return** pjp.proceed(); <<< !    } catch (Throwable e) {        e.printStackTrace();    }    }
