@frankly123 然后想在哪里读就在哪里读

/**

*/
public class WrapperRequestFilter extends AbstractRequestLoggingFilter {


/**
* Concrete subclasses should implement this method to write a log message
* <i>before</i> the request is processed.
*
* @param request current HTTP request
* @param message the message to log
*/
@Override
protected void beforeRequest(HttpServletRequest request, String message) {
//do nothing
}

/**

@Override
