AOP實現請求攔截

攔截controller層以s_開頭所有方法的，參考博文

@Before("execution(* com.top.sstore.controller.*.s_*(..))")  2     public void log(JoinPoint joinPoint){  3         //獲取RequestAttributes
        RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();  5         HttpSession session = (HttpSession) requestAttributes.resolveReference(RequestAttributes.REFERENCE_SESSION);  6         boolean b = userService.checkUserId((Integer) session.getAttribute(staticValues.getSessionUserId()));  7         if (b)  8             return;  9         throw new RuntimeException("未登錄");   //未登錄，拋異常
    }
