@Override
public ServletRegistration getServletRegistration( String s )
{
  return proxy.getServletRegistration( s );
}

代码示例来源：origin: Atmosphere/atmosphere

try {

    ServletRegistration s = config.getServletContext().getServletRegistration(config.getServletConfig().getServletName());
      s = config.getServletContext().getServletRegistration(VoidServletConfig.ATMOSPHERE_SERVLET);
