HttpServletRequest在方面方面自动进行a布线，因为这会将您的方面与只能在执行中调用的类一起运行

private String getRemoteAddress() { RequestAttributes attribs = RequestContextHolder.getRequestAttributes(); if (attribs instanceof NativeWebRequest) { HttpServletRequest request = (HttpServletRequest) ((NativeWebRequest) attribs).getNativeRequest(); return request.getRemoteAddr(); } return null;}
