額，代碼竟然不顯示

我再貼一下public?class?FirstListener?implements?ServletRequestListener?{

//?Public?constructor?is?required?by?servlet?spec

public?FirstListener()?{

}

@Override

public?void?requestDestroyed(ServletRequestEvent?servletRequestEvent)?{

System.out.println("request?destroyed?initParam="?+?servletRequestEvent.getServletContext().getAttribute("initParam"));

}

@Override

public?void?requestInitialized(ServletRequestEvent?servletRequestEvent)?{

servletRequestEvent.getServletContext().setAttribute("intiParam","yang");

System.out.println("request?initialized");

}

}
